Design and purpose of the hub on the Lada Grant. Tips from experts on replacing bearings

A wheel bearing malfunction is a common failure during the operation of a technical device. The reason for premature wear is poor-quality road surface and aggressive driving style.

Front wheel bearing

Replacing a wheel bearing is done independently, without special equipment, experience, or skills. Subject to the availability of spare parts, the replacement process will take no more than an hour, without the cost of car service.

Where are the front and rear hubs on the Lada Grant? Description, purpose

The front hub joint is located on the front left (right) side of the axle shaft. The rear hinge is located in the rear left (right) suspension block.

The main purpose of the bearing is to firmly hold the hub and ensure wheel rotation. Structurally, the front (rear) hub consists of:

• outer and inner metal frame;
• a separator in which metal balls and rollers are located;
• insulating rings;
• special filler - graphite-based lubricant.

Standard Features and Dimensions

Bearing parts for fastening wheels are made in different sizes. We are talking about the diameter of the hub. The dimensional characteristics of the spare part will always depend on the make of the car and the size of the rims. Manufacturers adhere to the rule: the cylinder of a metal product must always match the size of the car wheel. A special system, DLA, is responsible for determining these parameters. The fact is that large wheels on hubs of small diameter will dangle. Sometimes, for large-diameter wheels that a standard hub does not fit, an additional adapter ring is installed.

Resource for replacing hub mechanism elements

The average service life of wheel joints is 80 – 85 thousand km. The indicator is average, as it depends on the following factors:

• quality of workmanship of the part;
• frequency of operation of the technical device;
• driving style;
• quality of road surface;
• aggressive environment;
• high operating temperatures;
• compliance with technical inspection intervals.

Signs that a hub needs to be replaced

• the appearance of uncharacteristic noise during wheel rotation;
• wheel runout in the steering column;
• vibrations at different speeds. Sometimes there is vibration at a certain speed;
• metallic grinding noise as the wheel rotates;
• front wheel hub play.

Diagnostics of the hub mechanism

1. We place the car on a level platform, squeeze the parking brake if we are checking the front row. For the rear, we install wheel chocks.
2. Let's jack up the front (rear) part.
3. We turn the car wheel and carry out troubleshooting.
4. We shake the wheel up and down with our hands. In good condition there should be no play. Otherwise, we dismantle and replace worn elements.

What are the causes of the malfunction?

Below are two common reasons why a rear wheel bearing may fail.

1. The element loses its tightness. The product body contains a certain amount of lubricant, which reduces the friction of mutually contacting parts. The lubricant is retained by means of plastic housings with rubber seals present. These materials tend to degrade over time, causing loss of lubricant.
2. Large output due to the impressive mileage of the Lada Grant. In any case, even the most highly durable product in a car becomes unusable over time. Each detail has its own resource. For a bearing, this figure is at around 60 thousand km. Sometimes this chassis component shows signs of malfunction much earlier. This occurs during operating modes that involve driving over potholes and other off-road conditions.

Preparatory stage before replacing the hub mechanism

Required materials and tools:

• hydraulic (mechanical) jack;
• wooden stand;
• wheel wrench;
• screwdriver with a flat, cross-shaped bit;
• hammer;
• knob, nozzles;
• spanners;
• stationary vice;
• chisel;
• two-jaw and cup pullers. The exact dimensions of the pullers are indicated in the operating instructions;
• forceps;
• metal brush;
• lubricant type “CV joint - 4”;
• rags;
• caliper for measuring diameter;
• new wheel bearings;
• additional lighting provided that the work is carried out in the dark.

Is it worth buying the original?

Parameters and technical characteristics of the Lada Granta. Lada Granta VAZ 219010. Lada Granta model 219010

It is often advised to buy original bearings. An original is a part selected by a car manufacturer for sale on markets. These are the parts that are delivered to conveyors. When buying an original bearing, you will be absolutely sure that it will suit you. But there are several questions that need to be addressed here.

The original or a fake?

The original bearings are all the same and if you examine it carefully you will find the engraving. It is located on the edge of the upper or lower part. It should contain several information:

• manufacturer (logo);
• Country of Origin;
• designation digital or alphanumeric details, sizes;
• Additional information is possible;
• The kit must include a hub nut (usually disposable), there may be pins or bolts, seals.

1. SKF brand
2. Full bearing designation
3. Manufacturer country
4. Production date code
5. Deviation of the average outer diameter ∆Dm and the position of the maximum eccentricity of the outer ring
6. Deviation of the average bore diameter ∆dm and the position of the maximum eccentricity of the inner ring
7. Marking of thrust end, stamping
8. Serial number (for bearing sets only)
9. "V" marking (matched bearing sets only)

If the country of origin is not indicated, it is not an original, but a fake.

Is it worth paying extra for the original?

As a rule, you will find completely similar bearings from different companies on the market.

So is it worth paying more for the original if other companies produce the same parts? If you decide to pay attention to any company, then choose well-known, popular manufacturers that supply parts to conveyors. Some people prefer Japanese companies, others prefer European products, for example, they trust only German quality

Our rating of the best manufacturers will help you determine which wheel bearing company is better and who to give preference to. Even if these companies offer products made in China, they will be high-quality products that meet all the requirements. Pay attention not to the country of origin, but rather to the supplier’s brand.

Replacing the rear wheel hub of a Lada Granta

1. We place the car within the perimeter of the repair area and secure the front row of wheels with wheel chocks.
2. Using a wheel wrench, we tear off the mounting nuts, jack up the car, and remove the wheel.

1. We unscrew the screws securing the brake drum to the structure.

1. Remove the hub cap and remove the axle shaft from the splines.

1. We fix the structure in a stationary vice. Gently tap the outer edge with a chisel.

1. If necessary, use WD-40 liquid to remove deposits and rust.

1. We dismantle the hinge and use a vice, although some craftsmen use special pullers. In general, whatever is more convenient for you.
2. Using a metal mandrel, we knock out the inner ring.

1. To finally press out the hinge, use a hammer and chisel and gently tap along the outer perimeter of the frame.

Structure

The part has a fairly simple structure. Essential elements:

• outer rim (used for screwing in bolts);
• internal part (for bearings);
• holes with slots (for CV joint);
• protective caps;
• sensor (it is sometimes included in the design).

CV joints are constant velocity joints; their main task is to transmit torque.

Hubs for different purposes have different technical characteristics. Hubs for passenger cars have the form of a hollow, lightweight cylinder, while for “heavyweights” the diameter of the part is larger.

Replacing the rear wheel bearing of a Lada Granta with your own hands

Note to the driver!!! Before starting installation work, clean the surface from debris and dirt. Apply a thin layer of oil and be sure to lubricate the outer race of the hinge.

1. We install the new hinge and lightly press it into the cavity.
2. Evenly tighten the hinge until it touches the outer edge.
3. We fix the retaining ring and install the hub in its original place.

Installation in a regular place. Assembly of the structure

1. Apply a thin layer of graphite grease, put the assembly on the shaft, and secure it with a nut.

1. We complete the tightening with a torque wrench (tightening torque 30 Nm).
2. Use a chisel to counter the nut and put on the cap.

This completes the disassembly, assembly, and replacement of the rear wheel bearing.

Note to the driver!!! The Lada Granta Sport modification has a rear hub with a pre-installed ABS sensor.

It often happens that during the process of dismantling the hub mechanism, a bolt or pin breaks. The reasons for this are different, ranging from the old age of the metal to manufacturing defects.

So, how to remove a broken bolt. We carry out the work in several stages:

• mark the center of the stud;
• drill with a drill to 2.5, after 5.5, 9.5 mm;
• scroll with a bolt with a diameter of 9.5 - 10.0 mm;
• remove remaining metal and shavings.

What are the signs of a bearing failure?

Incorrect operation of the component we are considering is characterized by the presence of certain symptoms.

Next, let's look at the most common signs.

1. Manifestation of vibration on a moving Lada Granta car. This factor can be felt both from the steering wheel and spread around the perimeter of the entire body. This circumstance indicates an urgent need to diagnose the bearing, followed by replacement of the faulty unit.
2. A specific “howl” or hum, accompanied by crunching sounds while the Lada Granta is moving. These types of symptoms may indicate the presence of mechanical damage or dangerous partial failure of the bearing.

How to choose and buy quality parts

Service center specialists strongly recommend purchasing consumables and components exclusively from specialized stores, representative offices, and official dealers.

To a lesser extent, you need to use the services of unverified suppliers who sell spare parts at an unusually low cost.

When purchasing, check the catalog numbers with the actual data specified in the operating instructions for the technical device. If such a brochure is not available, consult a specialist.

Summarize

Now we can safely state that the replacement process is complete. As it turned out, the work did not cause any difficulties, but it did require stocking up on some special tools. Buy bearings for LADA Granta cars that are of only high quality and from trusted manufacturers in order to have confidence in your safety on the road.

Conclusion

Provided that the equipment is used moderately on uneven road surfaces, the average service life of CV joints is 85,000 km.

The better the quality of the road surface, the longer the hubs take care of. Original components will only increase the service life of the car. However, not all owners adhere to the recommendations of specialists and systematically save on consumables.

Choosing a new bearing for Lada Granta (VAZ 2190)

To do this, you need to know the original number of the Lada Granta bearing (VAZ 2190). The manufacturer AvtoVAZ indicates No. 21080-3104020. You can use GOST number 256706 AKE12. These two numbers are acceptable when selecting a part.

I also recommend using analogues:

— Russian manufacturer SPZ No. 2108-3104020;

— made in Russia VBF No. 2108-3104020;

— FAG German supplier No. 54512A;

- Swedish analogue of SKF VKBA1307.

Be sure to check the dimensions when purchasing. They should be like this:

— internal diameter – 30mm; — outer diameter — 60mm; - width - 37mm.

And of course, the part itself must be free of dents and rotate freely. Once you have purchased the bearing, you can begin replacing it.
