The manufacturer did not install a 4x4 transfer case with a switchable front axle on the Niva for a number of reasons, for example, to evenly distribute the load along the axles. But many SUV owners do not share this decision and try to make their car single-wheel drive. Do you know what uncoupling the front or rear axle of a VAZ 2121 does?
Installation of a disconnecting device
Disabling the front axle in the field does not cause any particular difficulties. A car enthusiast can produce it himself. The main thing is the sequence and accuracy of the actions: • You must first purchase the element to disable it.
- The floor covering is raised. The lever covers are carefully removed. The sensor terminal is disconnected. The lever switches to the “back” position. The transfer case is cleaned of dirt. The plug is unscrewed and the oil is drained. The front driveshaft is disconnected from the transfer case. The transfer case is dismantled. The nuts that secure the cover to the crankcase are unscrewed. The cover is removed and the coupling and shaft are dismantled. A new gasket is installed. The disconnecting element is installed in the vacant space.
• Assembly is carried out in reverse order.
You can watch the video at the bottom of the page for more details.
After completing the process, experts recommend checking the oil level in the transmission.
Using the front axle disconnect mechanism, the driver is able to switch operating modes of the car from the passenger compartment in a couple of seconds. You don't have to stop to perform the manipulation. Switching occurs even at high speed. This is quite convenient because, depending on the current situation, the car owner assesses the risks and quickly makes the right decision.
Recommendations
Experts recommend using the shift mechanism only when driving on asphalt roads, where the use of all-wheel drive is not necessary. You need to connect it when driving over rough terrain or in difficult weather conditions. Otherwise, the Niva runs the risk of getting into an accident or simply getting stuck in the mud.
Conclusion Nowadays, many foreign SUVs are equipped with a switching device at the factory. This is becoming a widespread phenomenon not only in Russia, but also far beyond its borders.
Installation of a special block
It is installed as follows:
- The axle drive housing has a cover; unscrew it with five nuts
- Remove the shaft and coupling
- We install the bridge block in place of the removed cover.
- Installing the transfer case in place
- If necessary, add transmission oil
The cost of this mechanism is around seven thousand rubles, but by installing it you will feel more confident when driving off-road, and at the same time save on gasoline when the need for all-wheel drive is not needed.
How to disable the front axle on a field: 1 comment
Yes, this was invented to squeeze out money. I drove 3 Nivas in 40 years and saw who removed the front driveshaft in order to disconnect the axle. A year later, I changed the rear one.
The Niva car became the first Soviet SUV to use an all-wheel drive transmission. A characteristic feature of the car is the center differential locking mechanism. There is an opinion among motorists that this mechanism serves to connect the front axle. However, the front-wheel drive Niva is always connected. You can figure out what drive the Niva has after studying the design of this unit.
Device for disabling the front axle on Niva
A more interesting way is to install a special mechanism that will allow you to untie the front gearbox from the transfer case using a lever from the passenger compartment. And there are such devices for both the regular Niva and the Chevrolet Niva.
The price of such a device: 6500 rubles.
It is installed instead of the standard transfer case cover and divides the gear into 3 components. A special mechanism connecting the gears allows you to: disable the front axle, turn on the lock, turn on the front axle. Control is carried out from the standard transfer case lever, and accordingly, one more position appears on it:
How to use the front axle disconnect? Everything is very simple. For a regular Niva:
On the Chevrolet Niva the scheme is similar:

Niva drive device
The chassis of the car is made on the principle of permanent all-wheel drive - torque from the power unit is transmitted to all 4 wheels. This scheme improves the performance of the car when driving in off-road conditions, while simultaneously reducing the load on transmission parts.
The Chevrolet Niva drive consists of the following components:
- Gearbox.
- Transfer case.
- A pair of drive and cardan shafts.
- Front and rear axle gearboxes.
The transfer case is designed to distribute torque between the drive axles of the vehicle. The car is equipped with a two-speed transfer case, which provides:
- stable running of the machine when driving at low speed and at high engine speeds;
- power distribution between drive axles, depending on road grip.
The differential is one of the most important elements of the transmission. Its main purpose is to distribute traction force, and, if necessary, ensure rotation of two consumers at different angular speeds. The Chevrolet Niva drive transmission has three differentials:
- One for each axle (inter-wheel) - they allow the wheels of the same axle to rotate at different speeds.
- The third (interaxle action) - transmits power from the power unit to both axles of the vehicle. It also allows the shafts to operate at different angular speeds, depending on operating conditions, which significantly improves controllability.
A pair of cardan shafts (CV joint or cross design) provide connection between the transfer case and the drive axle gearboxes. Both car shafts have the same design - they are interchangeable.
The front and rear axles transmit force from the transfer case to the drive wheels through external and internal angular velocity joints.
The principle of operation of all-wheel drive on a Chevrolet Niva
In normal mode, the Chevrolet Niva operates in high gear with the differential unlocked. Torque is transmitted from the power unit, through the gearbox and intermediate shaft, to a two-stage transfer case gearbox. A center differential is installed in the transfer case housing. It links the front and rear axles, allowing them to rotate at different speeds, depending on road conditions and direction of travel.
How does all-wheel drive work on a Niva with a locked differential?
When all-wheel drive is engaged, both cardan shafts are secured with a locking clutch. This promotes uniform transmission of traction force to both axles of the vehicle. Due to this, the vehicle's cross-country ability increases, but controllability deteriorates.
Advice: It is not recommended to use the lock mode on roads with good grip, as this will lead to accelerated tire wear, increased load on transmission parts and components, and will also increase fuel consumption.
All-wheel drive features
Chevy Niva is, as mentioned above, an SUV, which, unlike a regular car, has permanent all-wheel drive and its ground clearance is higher than that of a regular car, this is done so that it can be used without problems where there is off-road. While driving, the front and rear axles of this car are constantly running, and they are controlled by the transfer case. To reduce gasoline consumption, one of the bridges is turned off; when turning off, you should avoid surfaces where there is snow, ice or dirt. Let's look at what mechanism can be used to shut down.

How to enable all-wheel drive on a Chevrolet Niva? There is an option to block the center differential of the Chevy Niva both when the car is stationary and when it is not moving.
This is done with the clutch pedal depressed using the transfer case control lever, which is located behind the huge gear selector. When the lever is in the neutral position, you need to pull it towards the driver. If you later press in the opposite direction, a lower gear will engage with the center differential locked at a ratio other than 3.5.1. If you pull towards yourself, a lower gear is put into effect (gear ratio 1.5).

Changing from a lower gear to a higher gear while the car is moving is undesirable, although it is allowed in extreme cases.
It is not recommended to keep the center differential of the wheels in locked mode at all times, especially when driving on asphalt roads, as this will not only lead to increased fuel consumption by the vehicle and poor handling, but also to the breakdown of expensive transmission components.

how to turn on all-wheel drive in a Chevrolet
Since the Chevrolet Niva is a priori vehicle in all-wheel drive systems, then switching to all-wheel drive means activating the locking of the center (but not the cross-wheel) differential of the transmission. If the front axle is disabled in the Chevrolet box, all-wheel drive operates as normal. To do this, you need to use all the wheels of the Chevy Niva if one of them, say, hangs on a lever above the pit.
