Welcome, friends, to the DIY car repair website. When driving on our roads, the car’s suspension experiences enormous loads and the front springs are no exception, and they will be discussed today.
Replacing the front suspension springs of a VAZ 2107
Irregularities on the road and careless driving inevitably affect the condition of this element. But the importance of springs is difficult to overestimate - in combination with other suspension elements they provide comfort and smoothness.
In the event of a malfunction of this unit, replacement of the front springs of the VAZ 2107 is mandatory. But how to diagnose a breakdown? Is it possible to do the work yourself?
Removing and installing the VAZ 2107 front suspension spring
Place the car on a lift or inspection ditch;
holding the end of the rod by the flats with a wrench A.57070, disconnect the upper end of the shock absorber and remove the front wheels. Having straightened the locking plates, unscrew the bolts securing the caliper to the bracket. Move the caliper to the side and secure it so that it does not hang on the hoses. Remove the shock absorbers with brackets.
Disconnect the ends of the anti-roll bar from the lower control arms.
Using puller 67.7801.9513, press the pins out of the holes in the levers and move the steering rods to the side.
↑ Spring compression with device 67.7828.9504
1 — suspension spring; 2 — screw of the device; 3 - support plate.
- Insert screw 2 of tool 67.7828.9504 into the hole in the upper support of the suspension spring.
- Then place the support plate 3 on the spring coil 1 and on the screw 2 from below and secure it to the spring with a clamp.
- Screw the nut onto the screw from below so that the nut retainer fits into the socket of plate 3.
- By turning screw 2 with a wrench, compress the suspension spring until the suspension arms are completely unloaded.
- Take out the axis of the upper arm and disconnect it from the body.
- Disconnect the lower control arm axle from the cross member and remove the suspension assembly from the vehicle.
- Remove the spring, smoothly unloading it, remove the device and repeat the operations for the other suspension unit.
- Remove the engine splash guard and stabilizer bar.
NOTE! When removing suspension components, it is necessary to note the number and location of the adjusting washers between the axis of the lower arm and the cross member, as well as the adjusting plates between the cross member and the body side members, so that when installing the units, put these washers and plates in their original place.
↑ Installation of cross member A.70526 to support the engine when removing the front suspension cross member.
Supporting the engine with a cross member A.70526 or a hoist, remove the cross member.
Install suspension components and parts in the reverse order of removal.
Install springs on the front and rear suspensions of the same group (group A is marked with yellow paint, and springs of group B are marked with green). In exceptional cases, it is allowed to install group A springs on the front suspension, and group B springs on the rear suspension.
The front suspension should only have springs with yellow markings on the outer surface of the coils.
↑ Sequence of tightening nuts and axles in rubber-metal joints
To prevent improper distribution of forces in rubber-metal joints, tightening the nuts and lever axles must be done in the following order:
- Place the car on a level surface and place the wheels parallel to the axis of the car;
- load the car with a load of 3136 N (320 kgf);
- under these conditions, use a torque wrench to tighten the nuts securing the axles of the upper and then the lower arms and the nuts securing the axle of the lower arm to the cross member.
Check and adjust the front wheel alignment angles.
Conditions for replacement, tool
You can change the rear springs yourself even in the absence of an inspection hole (only a jack is sufficient). You can find out the dimensions of the socket heads and spanners required to unscrew the upper or lower shock absorber mountings in the repair and operating manual for your car model. In some cases, having two jacks will make the process much easier.
Replacing rear suspension springs will be much easier if you use special ties. For example, on a VAZ 2101, 2102, 2106, 2107, you can remove the old spring and install a new one using conventional installation, but the design of the rear suspension of many other cars will not allow such a trick. We will show you how to change rear springs without zip ties, but we recommend using this method only if absolutely necessary. The price of screeds is not so high as to sacrifice your own safety.
How to replace rear springs on a VAZ 2107
Replacement of rear springs on cars of classic models, such as the VAZ 2107, is carried out in two cases: if one of them significantly subsides or in case of mechanical damage. You should definitely remember that both need to be changed at the same time, otherwise the car will lose stability on the road due to tilting to one side. Unlike the front ones, replacing the rear springs does not require special tools and can be done in 1-2 hours without much labor. In particular, to replace the front springs you need a set of special pullers.
Rear springs for the VAZ 2107 are available in two sizes:
- Type A – length exceeds 273 centimeters – red color;
- Type B – length less than or equal to 273 cm – green color.
To work you need to stock up on tools:
- Two keys for 19;
- Two keys for 10.
In addition, you need to purchase two springs and two spare sets of rubber stands. If it is necessary to change the springs, then the stands may be suitable for further use. However, it is better to change them too while the car is disassembled, so that you do not have to do the same work again later.
To remove the springs on a VAZ 2107, you need to unscrew all the parts that interfere with the free movement of the bridge in the vertical plane. First, using 10mm wrenches, you need to unscrew the brake fluid pressure regulator rod.
After this, in order to avoid damage to the brake pipes, you need to unscrew the bolt securing the brake pipe tee using a 10mm wrench.
Next, use two 19mm wrenches to unscrew the lower shock absorber mount on the side where replacement is planned.
After this, we jack up the rear of the car on the side where you planned to work, the bridge lowers and the part is released. We take out the part to be replaced along with the upper and lower rubber pads, and install a new one in its place.
You should pay attention to the presence of protrusions on the linings on both sides. On one side the end of the coil rests on the protrusion, on the other we rest:
- into the protrusion on the car body for the upper lining;
- into the protrusion on the bridge platform for the lower lining.
After installing the part in its normal place, remove the car from the jack and screw on the shock absorber. The replacement of one element is completed, you can move to the other side. Having replaced both springs, we assemble the brake system parts in the reverse order. At this point, the work of replacing the rear springs can be considered completed. For VAZ 2107 vehicles with a long service life, before unscrewing the nuts, it is recommended to treat them with a special penetrating lubricant such as WD-40 to make work easier.
When to change springs
Two main signs that the VAZ 2107 springs need to be replaced::
- Damage appeared on the springs. This can be determined by visual inspection.
- The springs sagged a lot. This is noticeable in the reduction in ground clearance of the “Seven”, especially under load, and in the frequent breakdowns of the suspension when driving on a bad road.
In both cases it is necessary to make a replacement. Sometimes VAZ owners try to restore the stiffness of sagging springs using spacers. This decision is not entirely correct. The dynamic properties of a working spring and a spring with a spacer are different, which is why the suspension does not work quite correctly. In addition, cracks may soon appear on the reinforced sagging spring.
Replacing the front suspension spring of a VAZ 2107
Today we will talk about replacing the front suspension spring of a VAZ 2107 with your own hands. The article will be accompanied by photographs and a detailed description of all actions.
According to the length under the normalized load, the front suspension springs of the VAZ 2107 are divided into two groups: A - “long”
and
B - “short”
. The front suspension springs of group A are marked with yellow paint, the front suspension springs of group B are marked with green paint.
The vehicle must have springs of the same group installed. The front suspension springs on a VAZ 2107 should be replaced in pairs if at least one of the springs shrinks, deforms or cracks.
To do the work of replacing the front suspension spring on a VAZ 2107 with your own hands, you will need ties to compress the springs.
Warning:
Use only reliable factory-made ties to compress the spring and strictly follow the instructions for their use. The suspension spring has great strength. The spring breaking off the ties can cause serious injury.
How to remove the front suspension springs of a VAZ 2107
1. First of all, you need to prepare the car for repair.
2. Remove the front wheel from the car.
3. Remove the shock absorber from the VAZ 2107.
4. Loosen the two nuts securing the lower front suspension arm to the axle.
5. Disconnect the stabilizer cushion clip and remove the cushion.
6. Press the lower ball joint pin out of the steering knuckle.
7. Install the jack under the lower arm without loading the front suspension of the VAZ 2107, and unscrew the nut securing the pin.
8. Carefully unload the suspension (by lowering the jack) and at the same time, using a mounting blade, move the stabilizer through the upper stud securing its bracket.
9. Remove the jack.
10. Using a mounting blade, pry the spring from below and remove it from the lower arm support cup.
11. Remove the spring and the insulating rubber gasket from the upper support cup.
Installing a front suspension spring on a VAZ 2107
1. Before installing the spring on the VAZ 2107, attach the upper rubber gasket to the spring with insulating tape, ensuring that the end of the screw surface of the gasket coincides with the end of the spring coil. We install two ties on the spring, without catching them on the last turns, and tighten the spring to a height of no more than 280 mm.
2. Install the front suspension spring on the lower arm support cup and orient the spring so that the end of the spring coincides with the screw surface of the lever support cup.
3. Place the jack under the lower arm and lift it, making sure that the rubber gasket is installed on the upper support cup.
4. Raise the lever with a jack and guide the pin of the lower ball joint into the hole in the steering knuckle.
5. Tighten the self-locking pin fastening nut 4-5 turns. We loosen the ties and remove them through the technological hole in the lower arm.
6. Raising the lever, press in the pin of the lower ball joint and tighten the self-locking nut.
7. Install the remaining parts in the reverse order of their removal.
8. Having installed the car on the wheels, we finally tighten the nuts securing the lower suspension arm to its axle and securing the stabilizer pad holder.
9. Similarly, we replace the second spring of the front suspension on the VAZ 2107 with our own hands.
Let us remind you that the previous article was about adjusting the front wheel bearing of a VAZ 2107 with your own hands.
Which springs to choose for the “seven”
When choosing new springs (they are always replaced in pairs), it is important to comply with the markings and car model. Thus, springs marked 2101 (for rear-wheel drive sedans) and 2107 are considered standard equipment for the VAZ 2107.
The "Seven" lends itself well to tuning, so you can install springs from all VAZ models on it - from the "kopek" to the "Niva". However, you need to understand that “related” spare parts seriously modify the original properties of the car - they will increase ground clearance or load capacity, so you need to carefully think about the feasibility of such an installation.
Springs from foreign cars are also suitable for the VAZ 2107 - the easiest way, without additional modifications, is to install springs from Fiat and Nissan on the “seven”, since structurally these brands became the “progenitors” of domestic models, and therefore are as close as possible to them in design.
Imported springs have a longer service life, so they are preferable for thrifty VAZ 2107 owners
Spring manufacturers
Not wanting to experiment with the suspension, most VAZ 2107 owners simply buy standard springs - the ones that were already on the car. This is the best option, since in this case the performance of the car will definitely not deteriorate. Usually these are Lada-Image products.
Depending on the year of manufacture, as well as the preferences of the former owner of the car, a variety of springs can be installed on the “seven”. In addition, different manufacturers sometimes offer good equipment options for the VAZ 2107 at a reasonable price.
Sirius
The advantage of this manufacturer is that it works on all types of domestic cars, so you can find Sirius springs in any auto store or car market. The quality of the products is quite acceptable, but do not forget to change the springs every 30 thousand kilometers.
Also, upon request of the car owner, a pair of springs can be manufactured according to individual drawings, which allows the suspension to be equipped taking into account all the driver’s wishes.
The company produces a wide range of automotive products
Phobos
Phobos springs are cheap and of low quality. Car owners complain that the car begins to sag after two years of using such springs.
Depending on the driver’s preferences, you can buy Phobos products of both the standard type for the VAZ 2107, and with reinforcement or lowering to give new properties to the car. The manufacturer also offers play springs to increase ground clearance.
Phobos is famous for its affordable, but not the most reliable springs for cars
Technospring
Buying springs for a VAZ 2107 means spending money on optimal product quality. Today this manufacturer offers durable springs at a reasonable price. The degree of rigidity is lost during driving, but the car does not sag. “Technoressor” can be called one of the most budget-friendly options for equipping the VAZ 2107.
provides car owners with high-quality and inexpensive products
Koni
The manufacturer Koni makes springs that can be adjusted to suit your individual riding style directly on the car. The spring has a special device for adjustment, so such products are very much appreciated by tuning enthusiasts.
Koni springs are considered to be the most reliable and durable, even with constant driving on uneven roads. As the springs wear out, the body does not begin to sag, so they can be used even after they are worn out.
The springs have a shape atypical for domestic cars, and therefore their installation requires some modification of the chassis
Eibach
One of the most expensive and high-quality springs for the “seven” is Eibach. They are practically eternal and do not require replacement every 3 years. The manufacturer’s special technologies made it possible to eliminate the problem of loss of rigidity and sagging of the car. Even if the spring is heavily worn, the car will not sway while driving, and the driver will not feel a roll when cornering. However, the cost of such springs is very high - among all manufacturers they are the most expensive products.
High-quality products from the German manufacturer are famous throughout the world
SS20
This is the only manufacturer that selects a pair of each spring only after bench testing. Therefore, the quality of SS20 has become the main criterion for the brand.
For the VAZ 2107, you can choose a variety of types of springs, since the manufacturer produces all types of suspension equipment for most car models. Today SS20 is sold in 3 versions: hot wound, cold wound and with different compression ratios (depending on road conditions).
The purchase of these springs guarantees 100% identical performance characteristics of each spring in a pair
Kilen
The foreign manufacturer combines reasonable prices and suitable quality in its products. It is believed that the service life of Kilen springs is twice as long as the service life of standard Lada-Image springs, while the cost of the products is not much higher.
Kilen springs are an analogue of domestic products, equipped with maximum quality and service life

How to replace rear springs on a VAZ-2107
Over time, the elasticity of the metal decreases, the car sags, and in potholes the wheels begin to reach the wheel arch liners. It's time to replace the rear springs . The procedure is not complicated and a driver with minimal plumbing experience will be able to fix the problem on his own. This article is suitable for owners of all “classic” VAZs from 2101 to 2107 . Sometimes replacing the spring spacers with thicker ones helps. They are available in three versions with different thicknesses. If the springs haven’t burst, then the Zhiguli car is still ok with inflated spacers.
What to do?
If you find that the springs on the seven are broken, do not delay repairs. If you do not do it on time, then the destruction of other suspension components will begin along the chain, which will only make repairs more expensive. It is recommended to do all work in pairs - if on the front axle one spring is out of order, and the second is more or less “alive,” both need to be changed. Only in this case will you achieve maximum suspension efficiency.
If there is no damage to the springs, but there is subsidence, spacers can be installed. But it is not recommended to get carried away with such modifications, as the car’s characteristics deteriorate. The likelihood of skidding increases, and the braking distance also becomes longer. As for comfort, it also suffers. And in domestic cars like the VAZ-2107, the conditions are already Spartan. And if the mitigation of impacts on the body suffers, then the driver and passengers will lose all their teeth.
Replacing suspension springs on a VAZ-2107
We carefully inspect the suspension springs. Sagging springs, as well as those with cracks and severe corrosion, are replaced.
Check the technical condition of the insulating gaskets and replace them if they are damaged.
Replacing front suspension springs
To remove the front springs, we use a special device consisting of two grips installed between the coils of the spring and a screw tie.
Install the device into the spring and remove it.
Press the lower ball joint out of the steering knuckle (see Replacing ball joints).
We move the hub on the upper ball joint to the side. Use a 22mm wrench to loosen the nuts on the lower arm axle. (See Replacing the rubber-to-metal joints of the lower control arms on a vehicle.)
After making sure that the coils of the spring are tightened securely, push the lower suspension arm down and remove the spring along with the device from the lower arm.
A rubber insulating gasket is installed on the top of the spring
Having compressed the spring three times until the coils touch, check its elastic characteristics at the control points.
Replace the damaged gasket with a new one. The length of a working spring in a free state should be equal to 360 mm. It is allowed to install identical springs on the front suspension only with yellow markings on the outer surface of the coils (group A).
Installation of springs is carried out in the reverse order of removal.
We install the car on the wheels, and then tighten the nuts of the lower control arm axles.
Replacing rear suspension springs
We disconnect the shock absorber from the rear axle beam bracket and...
We compress the spring with two special ties.
Instead of zip ties, you can use two or three strong staples, which are inserted from two opposite sides into a spring compressed by the weight of the car.
When hanging the wheel, they will not allow the spring to fully decompress.
A compressed spring is dangerous, so in addition to ties or staples, you can tie its coils with steel wire.
Using your hands, move the rear axle beam down and remove the spring.
A plastic gasket is placed under the lower part of the spring, and a rubber vibration-isolating gasket is installed on top.
We check the condition of the rubber gaskets and, if necessary, replace them with new ones.
Install the spring in the reverse order of removal.
We replace the second spring in the same way.
We install both springs of the same group (with markings on the outer surface of the coils with paint of the same color).
Class “A” springs (yellow) are installed on VAZ-2107 cars.
It is allowed to install springs of class “B” (green color).
In case of damage (cracks, peeling), replace the compression stroke buffer by moistening it with a soap solution before installation
Logbook VAZ 21074 (2006)
Do-it-yourself: Front suspension: 5. Replacement of VAZ-2107 springs
So, we continue to rebuild the suspension. Today we’ll look at how to change the front springs, since the factory ones have already reached 220 thousand and are pretty tired, although the ground clearance is normal. To do this, I purchased similar springs from VAZ JSC with new spacers and a front spring remover.
Before replacing, to compare the effect, we will measure the distance from the floor to the wheel arch of the front wings before and after replacement with new springs, silent blocks and shock absorbers.
As we can see, the car has a skew of 1 cm on the right side, which is not critical.
Out of curiosity, let's measure the thickness of the new spring rod - if you subtract the painting, it is approximately 13 mm.
And the free length is 37.2 cm.
For work we will need:
- Keys and heads for 13, 22
- Central spring puller and ball joint remover (preferably)
- Crowbar or large screwdriver, hammer, wire brush
- WD-shka or other “liquid key”
We hang the car, remove the wheel, remove the shock absorber, loosen the nuts of the silent blocks of the levers, remove the stabilizer bracket and cushion - we will also replace it with a new one.
Now loosen the nut securing the lower ball joint pin to the steering knuckle and tear off the pin. We have already discussed how to do this earlier.
We place the puller plates under the maximum lower and upper coil of the spring and tighten until the lower end moves away from the cup and the tension between the levers is relieved.
It is worth keeping in mind that the puller is weak, the bearing under the lower plate fell apart when replacing the second spring, although it works well without it if you lubricate the washers. Production, it seems, is Kostroma.
Now we fix the upper lever with the hub assembly, remove the ball joint pin from the steering knuckle and lower the lever down, carefully remove the spring with the spacer.
Inspect the spring for damage. As we can see, there are traces of corrosion and interturn wear.
Let's measure the remaining length in the free state - compared to the new spring, there has been a shrinkage of about 1 cm.
Now, using a puller, we tighten the new spring, placing the cups approximately under the second turn from above and below.
We put a new rubber spacer on the spring and fix it with tape or tape so that the end of the rod rests against the recess on the spacer. We carefully place the spring between the levers, orient the lower end of the rod so that it rests against the recess on the metal cup of the lever.
Using a jack, insert the ball joint pin into the steering knuckle and tighten it.
Now we remove the puller and install the new shock absorber back.
Also, we put on a new stabilizer pad and fix it.
We tighten the silent blocks under load and put on the wheel.
Now let's re-measure the distance from the floor to the wing.
As we can see, the front suspension has risen by 3.5 cm, which shows us how much the old springs were already weakened - taking into account the length in the unloaded state, they lost about 2.5 cm in elasticity. Yes, and visually the lower arm has slightly changed its angle.
It remains to check the wheel alignment, since the angles of the levers have changed.
How to replace rear springs on a VAZ 2101 - 2107
- 183 6 175k
- 76 1 90k
A sure sign of the need to replace the rear springs on a VAZ Classic (2107, 2106, 2105, 2104, 2101) is sagging of the rear part of the body. Moreover, ground clearance is significantly reduced even at minimal loads.
Let us visually analyze the entire process of installing standard springs with medium spacers. You can also experiment a little and install springs with high spacers, but this is allowed if you install simple springs from 2101, their article number 21010-2912712-01, and not reinforced springs from 2102, article number 2102-2912712. What are the best springs to install on VAZ cars is described here.
Springs from 2102 are much higher than standard ones; if they are used in combination with high or medium spacers, they will most likely lift the car very much. Consequently, the travel of standard VAZ shock absorbers is not enough, which means you will also have to change the shock absorbers to longer ones, for example Moskvich ones. Part number: 402-2915006-A. Additionally, it will be necessary to carry out welding work to weld additional rings onto the shock absorber itself. But replacing conventional springs with cargo springs is necessary in cases where you load your Zhiguli every day.
The tools we need to carry out the work:
- two jacks, for example, “trapezoid” and “frog”;
- large screwdriver;
- two keys for 19;
- balloon wrench.
When it's time to replace
There are several signs by which you can determine that it is time to replace the springs. These signs are:
- Detection of damage and defects in the product design. This malfunction can be determined by visual inspection, but first you need to put the VAZ 2107 car on an overpass.
- Their significant subsidence. If the vehicle's ground clearance decreases significantly, this indicates sagging of the devices in question. Springs quickly sag in such cases when the car is used to transport heavy loads every day. Also, those cars that are used as taxis also require frequent replacement of the devices in question.
If you find a problem with the springs on a VAZ 2107, then you should replace them without delay. This will extend the life of other suspension elements and save money. It is recommended to replace devices in pairs, since replacing only one element will cause the body to skew, which will negatively affect driving. In some cases, spacers help when the springs have sagged but are not deformed. Experts believe that you should not get carried away with spacers, since the physical properties of a car with spacers are many times worse. As a result of such modifications, the suspension does not function correctly, which affects many factors: from control to comfort. Therefore, if necessary, it is better to replace the springs, both rear and front. We will learn how this is done on a VAZ 2107 from this material.
Replacing the front springs of a VAZ 2107
Replacing the front suspension elements on the “seven” is carried out according to the following scheme:
- First, you need to install the car on an inspection hole or overpass, and then begin to remove the wheels, having first jacked them up.
- The front shock absorber needs to be removed.
- The nuts that secure the lower arm to the axle are loosened.
- Using a second jack, you need to place it under this lever, thus adding the suspension load. This is done to make it easier to disconnect the stabilizer.
- At this moment, you can use special spring ties (if available) to secure the springs in a compressed state. This will make further removal actions much easier.
The front springs of the VAZ 2107 need to be changed in pairs, just like the rear ones.
Changing the rear springs on a VAZ 2107
Replacing the rear springs of a VAZ 2107 is carried out according to the following principle:
- Install the jack and remove the wheel.
- The pressure regulator rod in the brake system is unscrewed.
- The rear pipe tee bracket is unscrewed.
- The shock absorber fastener at the bottom is unscrewed.
- Jack up the car and thereby release the shock absorber and spring fasteners.
- Now you can remove the spring, which also has a rubber spacer. If the spacers are deformed, they should be replaced.
- Replace the removed springs with new ones, installing all the removed parts in the reverse order of removal. When installing products, it is important to purchase special ties, as shown in the photo below.
Replacing the rear springs is much easier and faster, so it will take half a day to replace all four products.
What springs to install
It remains to figure out the question of what springs to put on the VAZ 2107? Instead of standard products, you can install reinforced devices. The replacement principle is similar, but the result will be significant. The suspension with reinforced devices will become stiffer, but it is important to know that at the same time you will need to install new shock absorbers (more powerful).
Many car owners are wondering what springs are best to install on a VAZ 2107? The best option for a rear-wheel drive sedan is products marked 2101. They are quickly and easily installed in standard places and do not require modifications. When choosing products, you need to pay attention to their manufacturer. There are many manufacturers, both domestic and imported, but it is important to pay attention to the cost. When choosing, pay attention to the stiffness class of the springs, the number of turns and their thickness. There are two types of hardness:
- Type A, whose length exceeds 273 cm. They are red in color and are the toughest.
- Type B. Their length is up to 273 cm and their color is green. Such products have reduced rigidity.
In conclusion, it should be noted that the higher quality the product, the longer it will last. Therefore, when choosing, it is important to analyze for what purpose you need a car: to transport cargo or simply carry passengers.
