I turn off the Front Axle. I get: FAST, RESPONSIVE, QUIET and ECONOMICAL Niva!

The Chevrolet Niva all-terrain vehicle is structurally designed in such a way that all-wheel drive is always involved when driving. This is felt well if you find yourself in an impassable area, such as mud, swamp or snow. In such a situation, all four wheels of the car will be involved. But often, for motorists, the purpose of all-wheel drive and its operation become irrelevant, especially if the driver drives on city roads without difficult paths.

All-wheel drive will create inconvenient situations: excessive fuel consumption, unnecessary wear and tear on the main spare parts of the car, and sometimes when two axles are operating, a roar on the road may be felt. Therefore, a reasonable solution in this situation would be to temporarily disable the front axle on the Niva. This is not difficult to do if you have some knowledge on this topic.

All-wheel drive features

Chevy Niva is an all-wheel drive SUV, which is intended for use primarily off-road. Off-road driving involves the use of the front axle. More precisely, the front and rear axles are constantly in operation, only the synchronization of their operation is controlled by the transfer case. If you turn off one bridge, fuel consumption will decrease. But if the Chevrolet Niva is driven on a road surface with a dry and hard surface, then is there no need to use front-wheel drive?

In addition, the use of the front axle entails an increase in fuel consumption of 2.5 liters per 100 km. Therefore, it is not recommended to use front-wheel drive unless necessary. If you disable the front axle on a Chevrolet Niva, you should avoid road surfaces or off-road areas where there is mud, snow or ice. If you plan to travel to such surfaces, then the bridge should be included in the work in advance.

Thus, the owner of a Niva Chevrolet SUV should know how to disable the front axle and when should it be done? But first, let’s look at what the drive disconnect mechanism on the Chevy Niva SUV is.

Reviews and observations

Based on the experience of owners of the Lada 4x4 SUV, a number of advantages can be identified after disabling the front axle:

Fuel consumption can be reduced by 3 liters per 100 km. Savings in each case are individual and in some cases may be insignificant;
Dynamics improves. The car accelerates better on dry asphalt;
The maximum speed increases slightly;
Less vibration, howling and hum while the car is moving.

Rear-wheel drive on the VAZ 2121 has a number of disadvantages:

Significant reduction in cross-country ability;
Significant deterioration in controllability. With the front axle disabled, it is very difficult to drive on a slippery road; this is facilitated by the short wheelbase of the SUV. On the VAZ 2131 the situation is a little better;
The service life of parts is reduced. There is no safety margin for rear-wheel drive in the Niva's transmission;
In winter, the oil freezes in a disconnected bridge, so sometimes it is very difficult to start moving after a long stay.

Why buy an all-wheel drive Niva and then disable the front axle? No need to drive an SUV outside the city? Saving on gasoline? It is worth considering whether it will be possible to reduce vehicle maintenance costs when, soon after one of the bridges is disconnected, it will be necessary to carry out premature repairs.

What do you think? Are there situations when it is advisable to disable the front or rear axle? Maybe it would be better to modify the Niva to improve its off-road characteristics? For example, install a self-locking differential or mud tires?

About transfer levers

Remember, once and for all, in a stock Niva they do not disconnect or connect the front axle of the car. The front lever is needed to lock the center differential, which creates a rigid connection between the two axles, and the rear lever is needed to engage a lower range of gears. The Niva's drive remains permanently full in any case. This is what this car is famous for.

What does it mean that the front axle is untied in the field?

Car owners do not always know how to disable the front axle on a Niva, since not everyone likes the all-wheel drive of this car. As practice shows, many people want to make certain modifications to the car’s chassis and make the bridge switchable.

In this regard, Niva owners can be advised to use specially designed couplings that are capable of disabling the front axle. Moreover, this modification will save up to 2 liters. fuel, since the load on the power part of the machine is significantly reduced, and the friction in the bridge gearbox is also reduced.

There is an opinion among experts that unloading the front axle can lead to a significant increase in the load and friction force of the rear axle. However, disconnecting the front axle can lead to deterioration in vehicle controllability, especially in winter when driving on ice. It is not recommended to overload the vehicle by driving off-road with only one axle engaged.

Varieties

There are several types of these elements:

Equipped with coaxial drive shafts. This type is used on many SUVs. It gained such popularity due to the use of a single main gear for both axles.
With a misaligned driven shaft. There is no intermediate shaft here. The advantages of this system are high efficiency and noiselessness. Also, this box has a low curb weight.
With drive axle drive blocking. It is also installed on the Chevrolet Niva. Here it is possible to use all the torque without slipping the wheels, which is very important when driving off-road. The front axle engages only on difficult sections of the road. On asphalt surfaces, the SUV has a single-wheel drive (only the rear axle works). This allows you to reduce fuel consumption and, if necessary, increase cross-country ability (when the drive “closes”). There is also an interaxle forced locking.

Bridge disconnect mechanism

Engineers specifically developed a block for this purpose that removes torque from the front drive driveshaft, thereby disabling the front axle. This unit is not installed at the factory, but if desired, you can install it yourself. This device is controlled from the cabin, thanks to levers that control the transfer case. Most drivers disable it by removing the front driveshaft, and some even remove the rear driveshaft, thereby making the Niva front-wheel drive. This method is of course not prohibited, but it can lead to failure of such elements as:

Transfer case supports
Output shaft bearing
Cardan

Therefore, it is best if you install a special block, thanks to which disconnecting and disconnecting the axles will be problem-free and thereby eliminate the occurrence of negative consequences by completely removing the front or rear cardan. This block is a clutch that connects the front cardan and gearbox in the transfer case and is controlled by levers located next to the gearbox.

Bridge disconnect block

The block is designed to divert torque from the front cardan drive shaft, which actually entails physical disconnection of the front axle. Such a block was specially developed by Tolyatti engineers. The Niva Chevrolet car is not equipped with such a unit from the factory, so if desired, you can install it yourself. The block is a structure that is shown in the photo below.

The device is controlled directly from the interior of the SUV, using the transfer case control lever.

Disabling the front drive without this device is only possible by removing the front driveshaft, which is what most Shnivovodov actually do. Some craftsmen resort to removing the rear driveshaft, resulting in a front-wheel drive car. Of course, operating a Chevrolet Niva SUV without one of the cardans is not prohibited, but this will negatively affect some elements of the car. In particular, the transfer case supports, output shaft bearings, and also the cardan itself are damaged. In addition, if all-wheel drive is required, without a cardan, it will not be possible to use this function. Therefore, if you decide to disconnect the bridge, then you should do this using a device such as a disconnect unit.

As you can see, this block is a coupling that connects the front cardan in the transfer case with the gearbox. The shutdown unit is controlled from inside the Chevrolet Niva car using a lever located near the gearbox.

If you decide to install such a unit on your car, you should initially purchase it. The bridge disconnect unit is installed in the following order:

The 5 nuts of the axle drive housing cover are unscrewed.
The cover is dismantled together with the coupling and shaft.
The bridge block is installed in place of the cover that was dismantled.
Before installation, you may encounter the problem of the coupling falling out. To install the coupling in place, it is necessary to turn it with the groove towards the flange.
The transfer case is being installed in its place.
Check the transmission oil. If the level drops, it should be topped up.

The price for such a unit is about 6-7 thousand rubles, but its presence will always allow the driver to feel much more confident when driving off-road and save on fuel.

Disabling front drive

There are two levers inside the car under the dashboard:

the first is designed to change gears while driving;
the second serves to control the transfer case of the car.

Instructions for carrying out work

Many people believe that the second lever allows you to disable the front axle, but in reality this is not the case. The Chevrolet Niva SUV comes from the factory with all-wheel drive on all four wheels. The lever located under the dashboard is responsible for controlling the differential in the transfer case.

When the locking lever is moved towards the driver (towards you), it is locked. When you switch the lever back, the differential will be put into operation.

When the differential lock is on, the front and rear driveshafts rotate with equal torque. If the lock is turned off, they will rotate with different torques. To be able to disable the drive in order to save on fuel, it is necessary to install a shutdown unit and lock the differential.

Block location

When the axle disconnect unit is installed, in order to prevent the front axle from working, you need to move the transfer case lever to the required position. It is allowed to turn the front axle on and off not only at idle, but also while the vehicle is moving. A very important feature is that turning on takes no more than 2 seconds, as well as turning on the speed.

The shutdown block is a useful mechanism, the effect of which has been experienced by many Shnivovody. The only disadvantage of such a product is its cost, but in literally six months it will pay for itself by saving on gasoline.

Based on the information presented, it should be noted that the only obstacle to solving the problem is finances, so many Shnivovody (if the Chevrolet Niva is not used in off-road conditions) simply remove the cardan.

Based on reviews from Shnivovodov who operate an SUV without a cardan, it should be noted that the violations in the vehicle system are minor, but they exist! Therefore, such actions are taken at your own discretion. To summarize, it should be noted that the front axle disconnect unit is not only useful, but also a necessary device.

We help with all our wheels

How to enable all-wheel drive on a Chevrolet Niva? You can block the center differential of the Chevy Niva both when the car is stationary and while driving.

This is done with the clutch pedal depressed using the transfer case control lever, which is located behind the large gear selector. When the lever is in the neutral position, you need to pull it towards the driver. If you then press in the opposite direction, a lower gear will be engaged with a center differential lock and a gear ratio of 2.1. If you pull it towards you, a lower gear is activated (gear ratio 1.2).

When the lever is in this position, the corresponding yellow pictogram lights up on the dashboard. If you cannot follow these instructions, try repeating the procedure while driving the vehicle.

The correct sequence for engaging the rollover lock is given in the owner's manual for that vehicle. It states that such blocking must be carried out in advance, while the car is moving along a section of the road with a hard surface. The action must be performed when changing the steering wheel position. To prevent breakdowns and damage to differential parts, blocking is prohibited during slipping or when the wheels (wheels) are sliding. The mode is switched using the same lever.

Disabling the front axle by removing the cardan

One of the cheapest and easiest ways is to simply remove the front driveshaft. Niva becomes rear-wheel drive. Removing the cardan will take no more than 10 minutes, but this method has its own drawback - it is inconvenient, because to do such work you need to crawl under the car, and carrying the cardan with you when you suddenly need the front axle is not a very good idea. However, if the front axle is not needed in summer, then this method has a place to be.

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:

Transfer lever all the way forward - front axle disabled
Transfer lever in middle position - four-wheel drive, locking engaged
The transfer case lever is all the way back - four-wheel drive, the lock is off.

On the Chevrolet Niva the scheme is similar:

Lever all the way to the left - four-wheel drive, without locking
In the middle - four-wheel drive with locking
All the way to the right - front axle disabled

Excerpt from the instructions:

General rules for revision:

1. The untethered bridge must be fastened at three or four points that do not have a rigid connection with the engine. 2. The front axle beam and anti-roll bar are used as supports. 3. When determining the new position of the RPM, it is important to prevent horizontal displacement of the axes of the propeller shaft and axle shafts. The bridge can be uncoupled using a gearbox suspension kit from Chevrolet NIVA.

Therefore, most car owners prefer steel brackets made independently or in the factory. For cars taking part in off-road competitions, a version of the RPM steel body has been developed. This gearbox is structurally equipped with lugs for independent suspension. There are also additional subframes for extreme conditions of use of the NIVA. When installing the latter, the question: “how to untie the front axle” does not arise, since the gearbox is mounted in the subframe.

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.

What is the difference between Chevrolet Nivas of different modifications?

The Niva is produced on the territory of the Russian Federation by specialists from the GM-AvtoVAZ company . The first concept, number 2123, was first demonstrated in 1998. The model was considered a successor to the VAZ-2121.

Restyling affected only the body . Spaciousness and modernity are its main advantages. The manufacturer's tasks included:

providing complete comfort for the driver and passengers;
increase in wheelbase.

Due to the 1998 crisis, car assembly was done manually . After purchasing the plant, General Motors in 2002 created a new look. The Niva was produced with a radiator, a golden cross and received a new name - Chevrolet Niva.

The SUV was produced in 2 main trim levels:

L: electric windows, heated exterior mirrors (since 2004)
GLS: faux leather interior, 16-inch alloy wheels, audio equipment, isothermal tinted windows, fog lights, heated front seats.

The car was equipped with a 4-cylinder engine with a volume of 1.7 liters . A fuel injection system is provided. The maximum torque corresponds to 128 Nm. Since November 2006, the automaker has released the first Chevrolet Niva FAM-1 in one configuration: GLX.

Differences between the new product and its predecessor:

Opel Z18XE 1.8 liter engine;
5-speed manual transmission Aisin AG5 from Suzuki Grand Vitara;
transfer case located in the same block with the gearbox.

The car was produced with 2 airbags, an ABS system from Bosch, a 10-inch brake booster, and Turkish CV joints. The model has been discontinued since 2008.

As a result of tuning, engineers were able to create a new look for Chevrolet ˗ Trophy . The model is maximally adapted for off-road use. Its differences from the basic configuration:

breathers are located under the hood;
drive axles are equipped with self-locking differentials with high friction;
a mechanism that allows you to secure an electric winch.

In 2009, the design studio Stile Bertone specialized in car restyling . The new product went into production in 5 trim levels: L, LC, LE, GL, GLC. General characteristics:

central locking;
signaling;
steering column height adjustment;
German hydraulic booster;
audio training;
cabin filter.

Since 2015, the automaker has expanded its equipment line by developing the LE+ version . It is based on GLC. The new product was equipped with air conditioning, a full safety package, optimally sized tires from Continental Cross Contact, rear bumper protection, and unpainted moldings. The common features of models produced since October 12, 2015 include the installation of modernized engines taking into account the Euro-5 standard.

The 2022 model, taking into account the configuration, received new options and improvements:

elimination of poor sound insulation for GLC;
driver airbag;
the Era-Glonass system to automatically call emergency services for LE, GLC;
The LC, LE, GLC modifications feature deep tinting of the glass in the rear doors and tailgate.

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.

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.

Sequence of work

We purchase (make) a tying kit. When making it yourself, we drill holes in the pan in accordance with the diameter of the studs .
We securely install the car on supports, preferably above the inspection hole.
Drain the oil from the gearbox.
We dismantle the CV joint drives, having first freed the steering knuckles of the wheels.
Disconnect the front driveshaft from the flange.
We remove the axle gearbox from under the car.
On a flat working surface, separate the bottom tray and side covers of the RPM.
On top of the CV joint drive covers, using elongated studs, we fasten the earring brackets. It is possible to replace the installation sequence of covers and brackets, depending on the kit you choose.
Instead of a standard pan, we attach a reinforced one, with installed clamps for attaching the anti-roll bar to the beam. In addition to the factory gasket, we use sealant. The pallet will experience additional loads, so the tightness needs to be improved.
We hang the RPM with the rear mount on the stabilizer beam. We center the axis of the propeller shaft and the axis of its flange in the gearbox.
On the bridge beam we mark the fastening lugs for the brackets for the front suspension of the gearbox housing.
We weld the eyes to the bridge beam and perform anti-corrosion treatment.
We fix the earrings in the eyes using polyurethane or rubber silent blocks.
We check the vertical alignment of the propeller shaft and CV joint drives.
We attach the axle shafts and driveshaft, and secure the steering knuckles of the wheels.
Fill the gearbox with oil according to the operating instructions.
Without starting the engine or removing the car from its supports, check the free rotation of the wheels and front driveshaft .
We make a test drive, after which we re-inspect the car in the inspection pit.

The front axle decoupling is complete, your SUV has become much more comfortable on the highway and more reliable off-road.

Kit options

On sale you can find several different options for ready-made kits for decoupling the VAZ 2121 front axle gearbox. Let's look at some of them.

Ready-made kit kit ZSTehnology OPM-1 for untying the Niva RPM, which includes a steel front gearbox housing cover and brackets connected through silent blocks and welded to the front beam. The retail price of this complex is 3100 rubles. Among the disadvantages: you will have to buy additional clips and stabilizer bushings.

A more durable and complete ZSTehnology OPM-2 Ultra-PRO kit. Unlike the previous one, the package includes all the necessary parts and can be used on all modifications of the Niva. The price in stores is 4,000 rubles.

The kit for independent mounting of the VAZ 2121-2131 front axle gearbox from SONDA is a similar set of brackets and a steel plate for additional protection. The cost of such a set is 4100 rubles.

There are companies that are engaged in the modification of Niva cars; they can custom make a decoupling kit with better quality parts, which will increase the reliability of the unit. Some owners of domestic SUVs prefer to make homemade parts for decoupling the front axle.

What is the purpose of blocking?

This mechanism contains shafts and gears. The differential is intended to distribute torque from the engine to the wheels. In Niva, the main driving wheels are the rear ones. With the help of a differential, the wheels can spin at different speeds , for example, when cornering. In this case, one wheel travels a small radius, and the other – a large one. If there were no differential, the wheels would begin to slip, which would cause increased tire wear.

Lever location

When driving on a straight road, the thrust from the engine is distributed evenly between the wheels. If one wheel starts to slip, for example on ice, then the differential transfers more force from the engine to it. This mechanism is mainly installed on the drive axle. Niva has it at:

Rear and front axles.
Self-locking differential (front axle)
Rear axle differential
Between the axles (central). Located between the gearbox and axles.
Center differential

Modified versions

The Niva's standard transmission, for all its advantages, often causes uncomfortable noise in the cabin. This is generally related to the design, but using engineering developments, you can modernize it and make the car much quieter.

This approach has already been applied in VAZ-21213 cars; as a result, even at a speed of 100 km/h you don’t feel any unpleasant noise, you can talk calmly and hear your interlocutor without effort. For these purposes, a number of modernization methods have been used: from unloading the floor near the transfer case and manual transmission mounts, reducing the load on shaft bearings to smoothing out peak torques under conditions of increasing loads on the transmission.

The noise in the modernized Niva transmission is comparable to that of a Zhiguli. It becomes more comfortable to be in the car when driving off-road. Upgrade costs are negligible; modification requires only the master's understanding of the design itself and a little time.

Enabling the differential lock

On the Chevrolet Niva it is possible to turn on all three differentials at the same time . Thanks to this, the vehicle’s cross-country ability increases several times when driving off-road.

Forced locking means that the drive wheels are combined with each other, as a result of which they can rotate at the same speed. Thanks to the blocking, the traction force of the engine will be used to the maximum and transmitted to the wheels.

As already mentioned, the differential assembly consists of shafts and gears. With their help, the traction force is automatically distributed between the drive wheels. The differential is locked using a blocker (clutch) . In this case, when the driver turns on the forced locking, the wheels “become” connected to each other. This helps ensure that they rotate evenly.

Differential assembly

If the center lock is forcibly engaged, then the front and rear axles are also rigidly connected at once, which guarantees an even distribution of traction to all four wheels. Thus, the vehicle’s cross-country ability will be increased several times , which makes the Chevrolet Niva a real SUV.

Applying a lock

Not all cars are equipped with blockers, and therefore they will be vulnerable off-road. In this regard, Chevrolet is a unique car that can move with either one or all-wheel drive , which allows it to feel confident even on mountain roads.

To engage the differential lock, pull the lever all the way to the left.

Forced blocking should be enabled in the following cases:

When overcoming difficult sections of the route. In this case, the blocking should be turned on in advance, even before leaving for such an area.
On steep climbs or slopes when wheel slip is possible.
When driving on sand.
When driving on snow or ice.

Disable blocking

When the Niva moves on a regular road with a smooth surface, it will not need to lock all wheels. They will adhere normally to the surface and not slip, since the traction force from the engine will be distributed evenly over them. For this reason, when the car is moving on a good road where the wheels will not slip, the use of a differential will not be required .

Types of hubs in a car and their operating principle

There are two types of hubs:

manual (classic version),
auto,

The latter, in turn, is divided into three types, depending on the type of drive (electric, vacuum or pneumatic, hydraulic or mechanical).

Manual

The first - the manual clutch - is turned on and off by turning the handle to the desired position; the handle is located on the device itself, attached to the wheel. Hence the minus: for this action the driver has to leave the car. There are also advantages that outweigh the main disadvantage - manual hubs are more reliable and last much longer.

For example, for the Patriot they create a manual hub AVM (one of the most popular, the country of manufacture is Brazil), the American manual WARN is in second place in popularity, and the Ukrainian AmisA is in third place (a new technology has been introduced).

Auto

The second type of hubs is automatic and is included in the package of the SUV. After activating the hub, the rotation of the CV joints is blocked, the supply of torque to the shaft is stopped, and the clutch is completely removed from the clutch.

They turn on themselves when 4WD is activated, you just need to move off. To turn it off, you need to stop the car, turn off the four-wheel drive, and drive in reverse. In reverse, if before this the car was moving forward, if, on the contrary, it was moving backward, you need to drive straight (in order for the wheel and axle shaft to disengage, you will have to drive a couple of meters in the opposite direction).

This type of hub is easy to use (you don’t need to leave the car to disconnect the clutch), but unfortunately, the clutch is less reliable, fails in some cases (you have to connect it manually) and with it the chassis still wears out faster (than when operating a car with manual hub).

Automatic shutdown is made possible thanks to the drive: electric, vacuum or hydraulic.

How to choose the right hub for your car

Each type of hub has its own advantages and disadvantages. You need to choose a clutch for your SUV based on the characteristics of its operation: how often do you drive it, how often does the gravel road change to an asphalt one, how much time do you spend off-road.

If you don’t need to turn off the drive often (you’ve gone off-road and won’t be returning to city roads soon), choose a manual hub. If you often change driving conditions (for example, you live outside the city, but go to a metropolis to work) or drive more often on an asphalt road, the right choice is automatic.

: Do HUBS affect fuel consumption?

Automation repair costs the same as completely replacing the hub with a new one. To give the client the opportunity to save money, the service station offers a choice - to replace a faulty automatic one with a manual one. Sometimes this proposal actually turns out to be advisable. But even the installation of automation pays off quite quickly (due to increased productivity and reduced fuel and repair costs).

Choose hubs from manufacturers that are recognized as the best in their field (Brazilian, American, Japanese, Ukrainian).

Choose hubs according to their technical characteristics so that they fit your SUV perfectly: by the diameter of the holes, mounting bolts and length.

All-wheel drive, switchable all-wheel drive, hub advantages

Unlike models with plug-in 4WD, all-wheel drive SUVs, when returning from off-road to the highway, turn off the torque, but without a hub, the components and assemblies of the front axle continue to rotate due to the movement of the front wheels. As a result, speed is lost, parts of the entire chassis wear out, and fuel consumption increases. Perhaps this is partly why SUVs with plug-in drive are much cheaper (all-wheel drive, although they run on the asphalt with 4WD turned on, do not wear out so quickly).

When to downshift?

How to use the transfer case on a Chevrolet Niva, why and when to turn on low and lock? This seems like a trivial but serious question. It's simple. Just imagine, you are driving along a country road in fourth gear - the road is wonderful, but then a deep puddle appears in front of you, where, naturally, the road surface is soft and the car will sink. To do this, you need to stop and engage a lower gear. You are not mistaken, but you really need to stop.

The whole reason is that there is a center differential that simply will not allow you to switch from high to low and back. Why do you need a downshift at all?

Just imagine - you need to drive along a soft or heavily polluted section of the road. For example, you are driving in second gear and begin to feel that the car is heavy and something is slowing it down, you switch to first, but it is still hard for it, that’s what a lower gear is for.

The first downshift is like half the first upshift, that is, if you shift to the second downshift, you get the first upshift.

As a rule, low gear is designed for off-road use.

. When the low gear is on, you need to drive and it is advisable not to accelerate sharply, because at this moment the wheels receive a large load and can make a fatal hole that will not allow you to move further.

In this case, the car allows you to feel the movement of the wheels and if they start to dig in, you will immediately understand it by the chaotic movement. In this case, if you notice in time that the car is starting to slip, you can do something to avoid an ambush, for example, change the trajectory.

It is worth paying attention to the fact that if you are driving through deep puddles or sticky mud, then in no case should you sharply switch to the second lower gear, since the car may simply “choke” when the torque increases, which means it will become difficult for it and it will simply stall at the most inopportune moment.
