Replacing gearbox seals on a Lada Priora
Replacing gearbox seals on a Lada Priora is a rather complex process that must be carried out strictly according to all points in our manual. You can make the replacement yourself; we recommend doing it in a well-lit garage.
To replace the seals of the internal constant velocity joints (CV joints), drain the oil from the gearbox.
Replacing gearbox seals on a Lada Priora with your own hands.
1. Disconnect the front wheel drives from the transmission.
Warning.
Do not disconnect both drives at the same time, as in this case the axle gears in the differential may move and it will be impossible to install the drives without disassembling the transmission. If it is necessary to disconnect both drives, after disconnecting one of them, insert the process plug or the old inner joint housing in its place. After this, disconnect the second drive.
2. Using a screwdriver, remove the inner hinge oil seal from the box housing.
3. Press the new oil seal using a suitable mandrel until it stops with the working edge inside the box.
Note.
The oil drainage grooves on the seals of the right and left internal joints are directed in different directions.
For identification, arrows and part numbers are marked on the seals: on the right seal a (part number 2110–2301034–01) the arrow is directed counterclockwise, on the left seal b (part number 2110–2301035–01) – clockwise. The arrows show the direction of rotation of the wheels when the car moves forward.
4. Install all removed parts and assemblies in the reverse order of removal.
The reason for oily clutch discs may be a leak in the gearbox input shaft oil seal or the crankshaft rear oil seal.
Engine oil and transmission oil have different smells. Therefore, having a certain skill, you can determine by smell which of the oil seals is defective: the input shaft oil seal or the rear crankshaft oil seal.
Recommendation.
There is another way to determine the type of oil. Drop the oil into a thin layer of water poured into the vessel. The transmission oil will spread over the entire surface of the water in the form of a rainbow film, and the motor oil will remain in the form of a drop, similar to a lentil grain.
To replace the input shaft oil seal, you must remove the gearbox from the vehicle.
You will need: the same tools as for replacing the clutch release bearing, as well as a “10” wrench and a screwdriver.
1. Remove the clutch release bearing.
2. Remove the three bolts securing the guide bushing. Remove the guide sleeve.
3. Using a thin wire hook or a screwdriver, remove the oil seal. Press in the new oil seal using a suitable mandrel. The working edge of the oil seal must be directed inside the gearbox.
4. Install the removed parts in the reverse order of removal.
The gear shift rod oil seal can be replaced directly on the Lada Priora.
You will need: a 10mm wrench, a thin chisel, a hammer, and a mandrel for pressing the oil seal.
1. Remove the dirt boot from the joint and slide it over the shift rod.
2. Remove the bolt securing the hinge to the gear shift rod.
3. Then disconnect the gear selector rod along with the hinge from the rod.
Notes
. The bolt securing the hinge to the rod differs in length and color from similar bolts used in the gearbox to secure the forks and gear shift lever. This bolt is cadmium-plated (gold-colored), the rest of the bolts are phosphated (dark-colored). Do not replace this bolt with others.
Replace a bolt with a damaged taper shank or thread.
The bolt is fixed with special glue TB-1324. Before screwing in the bolt, clean it of old glue, degrease the threaded part and apply new glue. If special adhesive is not available, use a commercially available anaerobic thread locker.
4. Remove the dirt cover.
Notes
. Replace the torn or cracked dirt cover.
5. With the chisel resting on the collar of the rod seal race, use gentle hammer blows to press the race out of the gearbox housing.
6. Then remove it from the rod and seal assembly.
7. Using a suitable mandrel (you can use the socket from the tool kit), press out.
8. Now remove the oil seal from the race.
9. Press the new oil seal into the race until it stops with the working edge inside the gearbox.
10. Lubricate the working edge of the oil seal with transmission oil and, using light hammer blows, press the race along with the oil seal into the gearbox housing until it stops.
11. Install all removed parts and assemblies in the reverse order of removal.
Replacement of gearbox seals on Lada Priora has been successfully completed. Let us remind you that the previous article was about replacing the radiator of the cooling system on a Lada Priora with your own hands.

Replacing the gearbox seal on a VAZ-2110: when does it need to be replaced?
An oil leak from a VAZ-2110 car is a serious cause for concern. It is especially dangerous when oil begins to leak from the gearbox. As a rule, this problem is associated with wear of the rocker seal. If this problem is discovered, repair work must be carried out immediately.
Two ways to replace the gearbox seal on a VAZ-2110
It is easier to change the oil seal with the gearbox removed.
Replacing an element that has become unusable can be done in two ways.
- The first of them is very labor-intensive , since it will be necessary to remove the gearbox. But replacing the oil seal will be much easier.
- The second method seems less time-consuming and labor-intensive , but in practice it is very difficult to carry out this procedure. Only experienced motorists who have repeatedly had to repair their cars can replace the oil seal directly on the car without removing the gearbox.
Troubleshooting
Experienced car owners know the visual reasons why they can determine the failure of the rocker seal. Naturally, for such reasons it is impossible to accurately determine the cause of the leak, but this gives a signal to carry out diagnostics, in which the cause of the oil leak can be accurately identified.
The most important sign is oil stains under the car, especially in the gearbox area.
An oily rubber boot indicates a malfunction of the rocker seal.
But these spots do not always indicate oil seal failure. It happens that this is due to the oil filter, which sometimes does not tighten properly. In any case, the driver is obliged to monitor for any oil leaks in the checkpoint area . To do this, you need to monitor the oil level. This is the only way to save the box from damage, which will certainly happen if it operates with a minimum amount of oil.
Another way that indicates the oil seal is worn out is a characteristic crunch that is heard when changing gears . But only an experienced VAZ-2110 owner can diagnose this crunch. In any case, if you hear unusual sounds when shifting into gear, it is better to diagnose the gearbox.
Set of tools required for replacement
A minimum set of tools for replacing the oil seal without removing the gearbox.
In order for the replacement of a part to take place without problems, you need to prepare the place and the necessary set of tools in advance. You will need:
- A set of keys and sockets, and for 13 you need two keys and there must be a key for 10. There must also be a socket head for 22.
- A chisel or screwdriver will be needed to knock out the oil seal.
- The hammer is small so you can get under it.
- Silicone sealant.
- Awl and hook.
Additional accessories
A regular self-tapping screw will allow you to do without a special puller.
For those who decide to replace the gearbox seal without removing it from the car, you will need additional equipment:
- Several long screws.
- A piece of pipe for pressing in a new oil seal.
It should be noted that the replacement process without removing the gearbox is much more complicated. In addition, there is a possibility of damaging the part being replaced during pressing.
What parts to choose for replacement
It is better to immediately change the boot along with the oil seal.
Before you begin repair work, you need to purchase the necessary parts for replacement.
As for the oil seal, Balakovo products are very popular. You need an oil seal with article number 2110–1701043 and 21100-1701043-00 .
Manufacturers offer two options for oil seals - simple and reinforced.
In addition, it is recommended to immediately purchase a cardan boot, as there is a high probability that it is also worn out. Even if this is not the case, it may break during the repair process. Therefore, it is better to spend a small amount on anther than to bother with disassembly again.
Recently, reinforced oil seals have appeared on sale, which are called that way. If you believe the assurances of sellers, their service life is significantly higher than that of standard products.
Process in detail (algorithm)
It is recommended to carry out replacement work in a pit. In this case, you must take care of safety. The car must be secured using a handbrake and wheel chocks, which must be installed on both sides of the rear wheels.
Having prepared a workplace and a set of tools, you can begin to work. To replace the gearbox seal, you need to do the following:
- Most often, the VAZ-2110 wing is closed with a rubber boot.
If this part is covered in oil, this immediately indicates that the oil seal is really worn out. The boot needs to be bent. To do this, you just need to pull it by the wide part. Oil leaking from under the “glass” - the rocker seal definitely needs to be changed. - After this procedure, you will be able to see the cardan.
- Now it needs to be disconnected.
Otherwise, you will not be able to access the cuff. The cardan is disconnected from the lever and the rod using a 13 key. Before loosening the clamp, you need to put a mark so that you do not have to adjust the rocker later. - The nut must be completely unscrewed . This will loosen the connection between the driveshaft and the lever. First, the lever is removed.
- Now you need to disconnect the cardan from the rocker. To do this, you need to switch to first or third gear. After disconnecting, the part is removed.
- Now the boot is removed.
- Only after these procedures will access to the oil seal itself be opened. The part will be in the recess. It is from there that it needs to be extracted.
The oil seal is located deep in the bushing.
- It is very difficult to remove the rocker seal without special tools, so you will have to use various hooks. Alternatively, you can simply screw a self-tapping screw into the old oil seal, using it like a corkscrew.
We screw the self-tapping screw into the oil seal.
We take out the oil seal using pliers.
- After the old part is removed, you need to prepare a seat for replacement. It is cleaned of dirt and rust.
Only after this you need to press the new part into the rod. This procedure is quite complicated, since there should be no distortions. Many drivers use various homemade devices when pressing. When working, it is very important not to damage the new part, otherwise everything will have to be redone.
After the spare part is in its place, assembly is carried out in strictly the reverse order.
Conclusions (video)
If you are not confident in your abilities, you can watch a video that shows the entire replacement process in detail. Self-repair will guarantee that everything will be done efficiently, since the owner of the VAZ-2110 will control the process.

Pulley, or damper, generator drive, its purpose
The multi-belt drive of the generator and other additional units, when installed on the Priora, in addition to transmitting torque from the crankshaft, performs another important job. To understand its meaning, it is worth making a short digression into the ECM.
The principle of operation of an engine with an “injector”
Cars equipped with an ECM are radically different from conventional carburetor cars. The fact is that the ECU (Electronic Control Unit) is responsible for all the actions of the ignition and fuel supply systems. It is he who gives the signals for the formation of a spark in the cylinder chambers. And it sends signals for fuel injection by opening the fuel rail injectors. The question naturally arises, how does the computer know that it is time to issue commands to turn on the necessary nodes?
The crankshaft sensor informs him of this. It is worth considering this process in more detail. This sensor operates on the long and well-known Hall effect. That is, the signal is interrupted when a special technological clearance on the disc being read coincides with the sensor. On “injection” cars, this signal coincides with TDC (Top Dead Center) of the compression stroke of the first cylinder. So, you need to know that on Russian cars it is the pulley that does the work of the information disk.
Features of the pulley (damper)
The generator drive of the Priora, like other domestic cars, is called a damper. This is a Disk with streams, along the edge of which there is a series of teeth. In one place two teeth are missing. This is the desired position of the crankshaft, and it is from this that the computer starts counting. So, from the moment this opening enters the sensor’s coverage area, the Priora ECU sends signals to open the injectors and generate a spark in the cylinders, according to the usual scheme.
The engine operates according to tables stored in the ECU memory. From this it should be clear that the pulley not only powers the generator, but also gives the command to start the engine!

Repair and restoration work
Regardless of the repair, adjustment or replacement of the link, the need to disassemble this unit does not disappear.
The parsing process includes the following procedure:
- First, you need to remove the casing from the gearshift lever, or, more precisely, from its handle.
- The front of the car needs to be raised with a jack or placed on a pit.
- Unscrew the mounting bolts that hold the front console, and then remove it.
- Now you need to unscrew the six bolts that hold the rocker and also remove it.
- When dismantling, you should be extremely careful, paying attention to the condition of each part and element, so that if their condition is unsatisfactory, replace it with a working analogue.
- To gain direct access to the cardan shaft, oil seal and support, you need to bend the boot.
Now let's get back to the repair itself. In fact, depending on the condition of the components and the unit itself, several recommendations can be made:
- It is practically impossible to do without a special repair kit for repairing the backstage, fortunately it is inexpensive.
- If the bushing is deformed during the repair work, it will have to be replaced with a new one.
- If the driveshaft is loose (which needs to be verified), then the matter will not be limited to just one repair kit, since you will have to dismantle and install a new rocker.
- The hole in the lever axis must be examined in detail, checking for wear.
- The rocker pad is one of the common reasons leading to random gear shifting and the appearance of extraneous noise and vibration. Replacing it is quite simple, so even a beginner can cope with this task.
Changing the oil seal
Many owners of a VAZ 2110 can often observe a situation where, after a long period of parking the car, traces of oil are found underneath it (on the ground). The problem has two causes: wear or damage to the oil filter, or wear to the oil seal.
Interestingly, when replacing the oil seal with a new one, owners will have the opportunity to completely replace the driveshaft, boot or cushion. Very comfortably.
However, before starting repairs, you need to objectively determine the cause of the oil leak. To do this, you need to carefully inspect the oil seal and filter for damage or wear. Once you are finally convinced that the oil seal is faulty, you should begin preparation and direct repair work.
If the filter is fully operational and not damaged, then in this case, you should put the car in a pit or find another way that will make it possible to get to the bottom.
It would be wise to watch videos dedicated to this type of repair, as well as view other useful materials, including information about repairing the VAZ 2110 backstage.
After that, you can get down to the most important thing:
- The boot should be studied in detail and inspected. If oil leaks from the gearbox, then traces of it will certainly remain on the surface of the boot.
- To get to the cardan, you will have to bend the boot. Afterwards, disconnect it, thereby gaining access to the cuff.
- Dismantling the cardan should begin by disconnecting the lever, and only then freeing it from the rocker.
- Let's move on to the oil seal.
- Before removing the cuff, you need to prepare the hook and awl in advance, since it can only be removed thanks to them.
- To install a new oil seal, craftsmen often resort to using a standard plastic bottle cap. This is quite convenient in practice.
- After successful installation, we assemble in the reverse order.
