How to determine when it's time to change?

Under the influence of temperature and aggressive substances contained in the oil, the elastic cuffs become rigid. Rotating shafts gradually wear out rubber or silicone. As a result, the connection loses its tightness. This manifests itself in the form of oil leaks. If there is severe wear after parking, you can find oil drops under the car in the area of ​​the gearbox.

If the input shaft seal is damaged, lubricant leaks onto the clutch disc. As a result, the oil begins to burn, as evidenced by a characteristic odor. In this case, the clutch may slip under heavy load.

Important! Seal wear is also indicated by a drop in oil level. In this case, the parts must be replaced with new ones.

Advice on how to remove drives without dismantling the Niva front gearbox

  • To dismantle the drives, it is necessary to unscrew the fastenings of the gearbox (in this case, some kind of stop is placed under it).
  • Then the steering knuckles are released. To do this, simply unscrew the shock absorber mount from the lower arm and the lower ball joint.
  • To relieve the load, jack up the lower suspension arm.
  • Unscrew the hub nut and remove the centering ring. The nut is too tight, so we use a wrench extension (for example, a metal pipe).
  • We move the steering knuckle to the side. The drive can then move freely.
  • To ensure free movement of the drive during removal, the gearbox must be moved back slightly.
  • We remove the drive, being careful not to damage the anthers. If the boot is torn, it must be replaced.
  • The procedure for removing the right and left CV joint drives is similar.
  • Replacing the secondary shaft oil seal

    To work, you will need a standard set of wrenches, a hammer, a mandrel and a screwdriver. The materials you will need are sealant and kerosene for washing spare parts.

    Replacing the secondary shaft oil seal of the Niva Chevrolet gearbox requires preliminary dismantling of the oil seal. After this you need to do the following:

    • Remove the centering ring seal.
    • Unscrew the nut holding the shank flange.
    • Remove the centering ring.
    • Pull out the lock washer.
    • Remove the flange.
      Using a screwdriver, remove the oil seal from the mounting hole.

      Apply a thin layer of sealant to the outer surface of the body of the new part.

      Using a mandrel, press the part into the gearbox cover.

      After this, all that remains is to check the oil level and install the flush valve in place.

      To replace the input shaft seal of the Niva Chevrolet gearbox, it is necessary to dismantle the gearbox. After this, all that remains is to wipe its body with a rag and get to work. To replace a worn part, you must:

      Using a 13mm wrench, unscrew the nuts and remove the clutch housing cover.

  • Pry off the housing with a screwdriver and remove the part.
  • Clean and rinse the seat with kerosene.
  • Press in a new part.
  • Install the clutch housing cover and tighten the nuts.
  • When the replacement is complete, you need to put the box back in place.

    Preparation and disassembly

    To independently remove a leaking rear axle oil seal on a Niva Chevrolet, you will need the following tools:

    • standard set of wrenches;
    • slotted screwdriver and wheel wrench;
    • jack;
    • hammer;
    • wooden stand;
    • cloth gloves.

    Never neglect gloves when repairing a car: they will protect your hands from damage due to accidental impacts. The height of the wooden stand should be enough to support the rear axle with the wheel removed and the shock absorber unscrewed, otherwise oil will leak from it.

    Before removing the old seal, you will have to disassemble the rear hub assembly and remove the axle shaft. Disassembly is carried out in the following sequence:

    1. Place the car on a level surface and secure it with wheel chocks. Make sure the handbrake is turned off.
    2. Loosen the wheel nuts, jack up the car and remove the wheel.
    3. Clean the rear axle flange that protrudes beyond the brake drum from rust. Additionally, you can treat this area with WD-40 lubricant.
    4. Unscrew the 2 bolts securing the drum with a 12 mm wrench, then gently tap with a hammer to move it out of place.
    5. The drum is removed in 2 ways: by squeezing it out with the same bolts, screwed into other holes, or by knocking it with a hammer through a piece of wood. The methods can be combined, just be careful not to damage the edge of the drum with the blows.
    6. After dismantling, clean the seat on the axle shaft again to make the drum easier to remove.

    The next step is unscrewing and removing the axle shaft. In the VAZ 2131 Niva Chevrolet, 4 bolts securing it are held on the other side by a bracket holding the shock absorber.

    Transfer case device

    The Chevrolet Niva transfer case redistributes engine torque between the drive axles and, if necessary, changes the gear ratio and locks the center differential. The parts of this assembly require significant force. Therefore, RK gears and bearings operate in an oil environment.

    To prevent oil leakage from the transfer case, oil seals are installed at the joints of the housing and rotating drive shafts. They consist of two parts: a metal body and a rubber cuff, tightened by a spring. The latter ensures sealing of the connection due to the tight fit of the rubber to the shaft.

    Installing a New Seal

    After removing the axle shaft, the metal shield where the brake pads are attached will remain hanging on the copper pipe with the fluid, so it should be fixed by inserting the 2 upper bolts back into the holes. Then follow the instructions:

    1. Remove the thick rubber gasket from the rear axle flange.
    2. Pull out the old oil seal by prying it with a screwdriver or pliers. Clean the seat and wipe with a rag.
    3. Lightly lubricate the new seal with transmission oil and insert it into the socket of the Niva rear axle as evenly as possible.
    4. Using a round pipe adapter, press the oil seal into the socket with light blows of a hammer. You can use an old seal as an additional attachment.

    At the end of the procedure, you must thoroughly wipe all parts free of oil - the brake cylinder, pads, drum and metal shield. Before reassembling, it would be a good idea to check the axle bearing for wear and grease. Wear is indicated by difficulty turning, binding, or slight noise. If you discover a malfunction, take the axle shaft to the nearest car service center; you will not be able to replace the bearing without special equipment.

    To check the grease inside the bearing, you need to pry the plastic covering the rollers with an awl and remove it. Then add thick Litol-type lubricant inside and put the plastic in place, and then begin assembly.

    At the end, it is important to check the oil level in the rear axle gearbox of the Chevrolet Niva. The test is carried out on a fully assembled car, standing on a level area. The filler plug is unscrewed from the gearbox housing, after which the oil level is determined visually or using a thin wooden stick. If there is a shortage, you need to insert a hose of a suitable diameter into the filler neck with a watering can at the end, where the lubricant is poured. It is more convenient to top up with an assistant: you control the level, and the assistant gradually adds oil.

    Most Chevrolet Niva owners, due to the simplicity of the design, can independently repair their car. This is especially true for a large number of consumables, including those in the chassis of the car. One of the parts that requires periodic replacement is the Chevrolet Niva front axle oil seal. The need for repairs arises when an oil leak occurs from the axle housing and a knocking noise occurs. The main cause of grease leakage is due to a clogged breather.

    It is necessary to monitor at what stage the oil leak occurs. If, after intensive movement, while the gearbox is still hot, and after it cools down, it stops, then it is necessary to clean the breather. It may be clogged with dirt, which prevents the heated air from escaping outside. Therefore, it is possible to squeeze out fluid from the gearbox, even if the gaskets are in good condition.

    If the breather is working properly, but oil still comes out, then most likely you will need to replace the cover gaskets and o-rings. Typically, the design of the front axle provides for the presence of three rings: an oil seal located on the axis of the drive gear, axle bearings and oil seals for the right and left drive - the axle shaft hinge.

    Article, size and manufacturers of reinforced cuffs

    Initially, oil seals with an outer diameter of 68 and an inner diameter of 35.8 mm were installed in the transfer case. two types:

    • 2121-2302052 — one oil seal. A similar part is installed on the drive gear of the front axle;
    • 2101-2402052-01 — two oil seals in the Republic of Kazakhstan. The same part is located on the drive gear side of the rear axle.

    The installation of different seals is explained by the different directions of rotation of the drive shafts.

    Useful! Nowadays oil seals with article number 2123-1802120-12 are installed in the RC and axles of the Niva Chevrolet. They are designed for shaft rotation both clockwise and counterclockwise.

    Spare parts from the Balakovo plant (Rosteco) are popular. According to reviews from Chevrolet Niva owners, they are characterized by high wear resistance at an affordable price.

    How to turn on the transfer case on a Niva Chevrolet

    The transfer case is controlled using a lever. Features of the device allow you to turn on lowering and locking at the same time. To select a lower gear, you need to pull the lever up. To add a lock you need to pull it to the far left position. To make it easier to navigate, there are special symbols on the handle:

    How to use the lowering device correctly. Let's say a car is moving along a dirt road in second or third gear. If you come across a large puddle on the way, it is best to stop and engage a lower gear.

    The downshift is only activated when the vehicle comes to a complete stop. This is a feature of the Chevrolet Niva differential. At the same time, it is not necessary to completely stop the car to activate the lock. At the same time, having the lock turned on is not a prerequisite for off-road movement. Usually it is used only if there is a risk of the car hanging diagonally.

    But is it possible to turn on the lock not only in diagonal mode? Of course yes. But at the same time, the owner of a Chevrolet Niva may have some problems. Very often the lock jams and it remains on. At the same time, driving like this is not very useful for the car, especially at high speed. There are several basic ways to turn off the lock. To do this, you need to put the car in reverse, accelerate the car a little and try to dislodge the lock. This procedure needs to be done only at speed; this method helps quite often. To check whether the lock is enabled, you need to look at the dashboard, there will be a corresponding icon there.

    It is best to move in a lower gear slowly, tightly, to feel the rotation of the wheels. In this case, it is important not to press the gas pedal so that the wheels do not spin, otherwise the car will begin to dig into the mud.

    When and how do you need to change the seals of the VAZ 2123 transfer case?

    Reference! Parts must be replaced if transmission oil leaks occur at the interface between the drive shafts and the transmission housing.

    If this is not done, the transmission will leak. Without lubrication, transfer case parts will quickly fail.

    Step-by-step instructions for replacing the oil seal of the Niva Chevrolet

    To work, you need to have free access to the bottom of the car. Therefore, replacement of the oil seals will be carried out on an inspection ditch, overpass or lift.

    You will need the following tool:

    • hexagon 12;
    • open-end or socket wrench 24;
    • waste container;
    • flat screwdriver;
    • hammer;
    • mandrel;
    • syringe for filling transmission oil;
    • new self-locking nuts for fastening the flanges.

    The algorithm for replacing the Niva Chevrolet transfer case oil seal is as follows:

    • drain the oil from the transfer case into the prepared container;
    • unscrew the bolts securing the cardan, the drive shaft oil seal of which is to be replaced;
    • engage the gear, lock the differential and put the car on the handbrake;
    • Unscrew the nut securing the propeller shaft drive flange.
    • remove the washer;
    • pull the flange off the shaft;
    • use a screwdriver to remove the old oil seal;
    • clean the seat and apply sealant;
    • lubricate the rubber seal of the new oil seal with oil;
    • using a mandrel and a hammer, press the part into place;
    • install the flange and washer, tighten them with a self-locking nut;
    • secure the cardan.

    Important! The self-locking design does not allow for reuse of parts. Therefore, the flange nuts must be replaced with new ones.

    After completing the work, it is necessary to fill the transfer case with fresh transmission oil.

    Front axle structure.

    To replace the oil seal, it is not necessary to dismantle the front axle. When replacing oil seals yourself, it is not recommended to use a lift; it is better to carry out the work on an inspection pit or overpass. The rear wheels must be secured with supports. The gearbox and transfer case levers must be adjusted to the neutral position. When using a jack, it is better to hang the front part on special supports.

    First, the replacement area is cleaned of drips and traces of technical fluids. After this, the crankcase plug is unscrewed and the oil in the gearbox is drained into a special container. After this, the plug is installed in place.

    To carry out the replacement, you need to stock up on the following set of tools:

    • set of socket wrenches and hexagons
    • hammer and pry bar
    • Screwdriver Set
    • puller with two or three legs
    • pipe sections equal to the diameter of the seals
    • Liquid for removing oil residues, such as kerosene
    • metal mesh
    • rags

    When to change the seal

    Replacing the axle seal is not tied to a specific mileage, but is done in connection with the following defects:

    1. Transmission oil leakage from the rear axle of a Chevrolet Niva. It is characterized by the appearance of oil stains on the brake casing and the “stocking” on the side where the axle shaft seal has lost its seal.
    2. In case of accidental damage to the seal when replacing the axle bearing. Happens when a part is pulled out of its socket.

    A distinction should be made between transmission oil leakage from the axle seal on either side of the rear beam and from the gearbox shank where the driveshaft is secured. In the second case, greasy stains and dirt cover the rear axle gear housing, located in the middle.

    If for various reasons you need to replace the axle bearing, then you should also change the oil seal at the same time. This will save you from having to disassemble the unit again due to leakage of the old part. The part costs mere pennies, its catalog number for the Chevrolet Niva is 2110-2301034 (right) and 2110-2301035 (left), and the overall dimensions are as follows:

    • outer diameter - 57 mm;
    • width - 9 mm;
    • The diameter of the hole along the protruding rubber (or silicone) edge is 35 mm.

    The catalog number and dimensions of the O-ring of the Niva VAZ 21214 axle shaft are identical. In addition to the oil seal itself, transmission oil will be needed to replenish the lost amount in the gearbox. TAD17I brand oil is considered “native” for all types of VAZ gearboxes.

    When and how do you need to change the seals of the VAZ 2123 transfer case?

    Reference! Parts must be replaced if transmission oil leaks occur at the interface between the drive shafts and the transmission housing.

    If this is not done, the transmission will leak. Without lubrication, transfer case parts will quickly fail.

    Transfer case oil seal Niva Chevrolet dimensions

    Tools:

    Parts and consumables:

    Note:

    We carry out the work on an inspection ditch or overpass.

    1. We replace the shaft seals of the front and rear axle drives by disconnecting the cardan shaft flanges from the shaft flanges, as described here. We change the transfer case drive shaft oil seal only after removing the intermediate shaft, as described here. The operations for replacing all three oil seals are the same - we will show them using the example of a rear axle drive shaft oil seal.

    2. Drain the transfer case oil as described here.

    3. We insert two bolts into the holes in the flange and screw the nuts onto them.

    4. Using a 24mm socket, unscrew the flange mounting nut, holding it from turning with a screwdriver or a mounting spatula inserted between the bolts.

    Warning:

    Self-locking nuts must not be reused; replace them with new ones!

    5. We remove the washer.

    6. Remove the flange.

    7. We pry off the oil seal with a screwdriver.

    8. We remove it from the transfer case cover socket.

    9. Apply sealant to the seating surface of the housing in the crankcase under the oil seal. Apply Litol-24 lubricant to the working surface of the new oil seal.

    10. We press in the oil seal with a piece of pipe or a tool head of a suitable size.

    Helpful advice:

    You can use an old oil seal as a mandrel.

    Warning:

    The transfer case shaft seals have the same mounting dimensions, but have oppositely directed oil drainage notches. When installing, follow the direction of shaft rotation indicated on the oil seal.

    11. We install the dismantled parts in the reverse order. Apply sealant (threaded) to the threads of the flange nut and tighten the nut with the prescribed torque H*m(kgf*m)96–117.6 (9.8–12.0), using a torque wrench.

    We check the oil level in the box as described here and, if necessary, top up.

    When replacing, the oil seal must be placed on sealant. I've written about this many times, try searching for ABRO.

    Before you shoot anything, find out what the sound is and where it comes from. I doubt it's a bearing. Maybe some shield is resonating, maybe it’s touching something.

    Thank you. Today I installed oil seal 2121-2302052 on the rear axle flange. I hope this is true? Otherwise, the first time I put 2101-2402052 there from the classics and it drained my oil in a terrible way. By the way, is it really possible to change the oil seals in the front and rear axles on a lift without a torque wrench? One service center told me that the shank nuts are tightened very cleverly. And what if they are not tightened correctly, then you can safely change the gearboxes

    We remove the axle shaft, select tools, consumables and accessories

    First of all, you should pay attention that when replacing a bearing, you need to install not only it, but also new axle shaft seals and new retaining rings. For cars with and without ABS, the locking rings are different - on cars without an anti-lock braking system, the axle locking ring has a smooth surface, and on cars with ABS, the locking ring is splined. It is impossible to confuse them. We assemble tools and accessories :

    1. Bulgarian.
    2. Standard set of tools and screwdrivers.
    3. Inertia axle puller.

    Inertia axle puller.

    New set - oil seal, retaining ring and bearing.

    The tool has been selected and the axle shaft can now be removed. This is done in the following sequence :

    1. We place the car on a flat surface and install wheel chocks under the front wheels.
    2. We tear off the wheel mount, jack up the car, and install a stand under the rear axle.
    3. Remove the wheel and unscrew the brake drum mounting screws.

    We unscrew the bolts securing the brake drum to the axle shaft.

    We knock down the brake drum using a wooden block.

    We unscrew the four nuts of the axle bearing mounting plate bolts.

    We remove the axle shaft using an inertial puller.

    When removing the axle shaft, you need to try not to damage the oil seal if there is no desire or need to change it. After this, the entire brake mechanism is suspended from the spring using a wire.
