The front wheel drive system is one of the most loaded components in the car design. Skoda Octavia Tour. It is through this transmission that the torque from the transmission is transmitted to the wheels, ensuring the movement of the machine. With intensive operation, especially in conditions of Russian roads with pits and poor surface, rubber protection elements begin to collapse.
Breakthrough duster This is not just a cosmetic defect, but a signal of a serious breakdown. The dust protects the hinge from abrasive dust, dirt and moisture. If the integrity of the rubber is broken, the lubricant is washed or dried, and small particles enter the inside, which act as an abrasive, quickly destroying the inner surfaces of the mechanism.
Owners Octavia Tour Often faced with the fact that the replacement of the entire node in the collection is unreasonably expensive. However, with minimal skills and tools, you can only replace them. rubber cover And lubrication, saving a lot of money. The main thing is to understand how to properly remove the drive without damaging other elements of the suspension, and choose high-quality components.
Malfunction diagnosis and characteristic symptoms
Identifying the problem early is fairly easy if you are attentive to changes in the vehicleโs behavior. The first and most reliable sign is the presence of lubrication traces on the inside of the front wheel or on the suspension elements next to the drive. Often when leaving the garage on a clean asphalt, you can notice black divorces left by the flowing thick lubrication.
If you notice the stains, you need to immediately check the condition. anther. Visual inspection is not always easy due to dirt and dirt, so it is best to lift the car on a lift or viewing pit. Hands feel the rubber cover along the entire length, paying attention to cracks, tears and traces of clamps that may have weakened. Skoda Octavia Tour It has fairly accessible access to this node, which simplifies the task.
In the later stages of wear, when the lubricant is already completely washed out, a characteristic knock or crunch appears. It usually occurs when a sharp start from a place, especially if the car is loaded. Sometimes the sound can be confused with a faulty hub bearing, but the difference is that the crunching of the SRUS varies depending on the steering wheel and the load on the drive. If you hear foreign sounds, do not delay repairs.
Required tools and supplies
For a quality replacement of the anther, you will need a set of tools that most motorists who are engaged in self-repair have. You will need: cap keys and heads (usually on 13, 17, 18, 30 and 32), a collar, a rattle, a hammer, a mount and screwdrivers. It is also crucial to have a stop ring removable or a flat screwdriver of the right size to dismantle the stopper.
The key is to choose the right spending. Do not try to save on lubrication, as it depends on the service life of the node. Use a specialized one. lubricant for CV joints based on molybdenum disulfide or graphite. Conventional lithium oil or graphite lubricant is not suitable for the high loads and temperatures characteristic of the inner hinge.
You will also need a new stain. For Octavia Tour The best fit original components or quality analogues from proven brands. Pay attention to the equipment: in the set are often new clamps (steel or plastic). Cheap clamps may not provide tightness, which will lead to repeated failure.

- โ Installation and hammer for dismantling the drive
- โ Special lubricant for shruss (about 150-200 grams)
- โ New anther and clamping kit
- โ Brake cleaner and rags to remove old dirt
Donโt forget to prepare a container for draining old oil from the gearbox, as when removing the drive, some of the oil will inevitably leak out. This is especially true for manual transmission models where oil levels can drop critically.
- Mechanical (MQ200)
- Automatic (Aisin)
- Robot (DSG)
Step-by-step algorithm for dismantling the drive
The process begins with lifting the car. Install Skoda Octavia Tour on a flat surface, tighten the hand brake and place recoil stops under the rear wheels. Remove the wheel from the side where the replacement is planned. Donโt forget to loosen the hub mount bolts even before the machine is lifted to avoid scrolling the wheel.
Next, you need to dismantle the steering tip or unscrew the ball joint nut to free the hub. Most often, it is enough to unscrew the nut securing the ball joint to the steering knuckle and knock out the pin. The hub should move freely from the drive. If the drive does not give in, use a special puller, but you can carefully pry it off with a pry bar, being careful not to damage the CV joint teeth.
After releasing the hub, the drive must be pulled out of the gearbox. This is the most crucial moment. The inner CV joint is held in place by a retaining ring inside the differential. With a sharp jerk or careful knocking out through the wooden spacer, it is necessary to release the assembly. Attention: Be prepared for oil to leak out of the box, so place a container in advance.
โ ๏ธ Attention: When removing the drive from the gearbox, be careful not to damage the gearbox seal. If the oil seal shows signs of wear, it is better to replace it immediately to avoid subsequent oil leaks.
Once the drive is removed, it can be placed on a workbench or clean floor. If you do not plan to change the CV joint itself, but only the boot, make sure that the inside of the unit has no obvious play or damage. Wash the housing to remove old grease and dirt before starting work.
โ๏ธ Dismantling of drive
Replacing the boot and lubricating the unit
Now let's move on to the replacement process itself. If the drive is removed, you need to remove the old boot. To do this, simply cut off the old clamps and pull the rubber off the CV joint housing. If the boot is stuck, use a knife, but be extremely careful not to damage the metal of the hinge housing. After removal, the rubber must be thoroughly cleaned of old grease with a solvent.
The next step is to disassemble the inner CV joint to change the lubricant. You need to knock the shaft out of the joint housing. This is usually done through a wooden spacer to avoid damaging the teeth. After removing the shaft, inspect the inner race and balls. If they have wear, scuffing or pitting (metal chipping), then replacing the boot does not make sense - the entire assembly requires replacement.
If the joint is in good condition, thoroughly clean all parts of old grease. Apply a new one lubricant inside the body and onto the balls. Do not skimp on lubricant, but do not overdo it, so that excess does not create excess pressure. Place the new boot on the shaft, first placing a new clamp on it from the inside.
It is important to tighten the boot correctly. It should fit snugly around the CV joint body without twisting or forming folds. After this, install a new clamp from the outside. To tighten, use special pliers or, as a last resort, a screwdriver and a hammer, but do it carefully so as not to tear the rubber.

- โ Inspect internal components for wear
- โ Fill the housing with new grease and put on the boot.
- โ Secure the boot with new clamps
Why canโt you use a regular lubricant?
Conventional lubricant cannot withstand the extreme temperatures and loads inherent in a CV joint. It quickly washes out or burns out, leading to rapid wear of the hinge and destruction of the boot.
Installing the drive back into the car
Reinstalling the drive requires care and strength. Insert the inner CV joint shaft into the gearbox until it clicks. This click means that the retaining ring has entered the differential groove and is locked. Check the secure fit by trying to pull the drive towards you. If it dangles, it means it hasn't gone all the way.
Then insert the inner end of the drive into the hub. Place the hub onto the shaft splines, making sure they line up completely. Secure the hub with the nut, but do not tighten it completely. Now you need to screw on the ball joint or steering end, depending on the design of your suspension Octavia Tour.
After assembling the suspension, you can lower the car to the ground. Only when the wheel is on the ground and the load on the suspension has been restored can the hub nut be finally tightened. The tightening torque must comply with the manufacturer's recommendations, usually about 200-250 Nm. Don't forget to install a new nut cap.
| Parameter | Meaning | Note |
|---|---|---|
| Hub nut tightening torque | 200-250 Nยทm | Only after lowering the car |
| Wheel bolt tightening torque | 120 Nm | Crisscross |
| Ball joint tightening torque | 30 Nยทm + 90ยฐ | Depends on year of manufacture |
| Transmission oil level | According to the control hole | Check after replacement |
If you spilled oil during dismantling, be sure to add it to the required level. This is critical to the longevity of the transmission. Use only oil recommended by the manufacturer that meets the viscosity grade and specification.
Correctly tightening the hub nut only after lowering the vehicle to the ground is the key to ensuring that the hub bearing is not overtightened or undertightened.
Checking the quality of work performed
After all work is completed, a test drive should be carried out. First, drive at low speed and listen for any extraneous noise. Then try to accelerate sharply from a stop and check if there is a knocking noise when turning the steering wheel. If everything is in order, you can accelerate to normal speed.
Please note that there is no vibration during acceleration. If vibration persists, the drive may have been installed incorrectly or the wheel may be out of balance. Also check if oil is leaking from the gearbox where the oil seal is installed. If there is a leak, the seal must be replaced.
During the first few days of use, carefully inspect the new boot. Make sure it does not fly out of place or twist. If you notice the slightest signs of fastening instability, it is better to immediately recheck the tightness of the clamps to avoid repeated repairs.
โ ๏ธ Attention: If after replacing the boot there is a knocking noise when starting from a stop, you may not have fully inserted the drive into the differential or damaged the retaining ring during installation.
Regularly checking the condition of the boots should be part of your maintenance schedule. This is a simple procedure that can save you thousands of dollars in replacement of the entire drive assembly. Don't ignore even small cracks in the rubber.
How often do you need to check the CV joint boots on the Skoda Octavia Tour?
It is recommended to check the condition of the anthers at each scheduled maintenance, as well as when any extraneous sounds appear in the suspension. In bad road conditions, it is better to check every 10,000 km.
Is it possible to drive with a torn boot?
You can drive, but it is highly undesirable. Even a small hole will quickly allow dirt and water to enter, which will reduce the life of the CV joint from several years to several hundred kilometers. The sooner you replace the boot, the cheaper the repair will be.
Do I need to change both drives when replacing one boot?
No, it is not necessary to change both drives. It is enough to replace only the one with a damaged boot. However, if the car has a high mileage, it is worth inspecting the second drive for wear, since they operate under the same conditions.
What to do if you canโt remove the drive from the box?
Do not use excessive force to avoid damaging the seal or differential. Try using a puller or carefully pry it off with a pry bar. Sometimes heating the seal with a hairdryer or WD-40 helps. If this does not work, it is better to contact specialists.
Replacing the inner CV joint boot with Skoda Octavia Tour This is a task that you can easily complete on your own. The main thing is to follow the sequence of operations, use high-quality materials and take your time. Regular car care will extend its life and ensure safety on the roads.
โ ๏ธ Attention: Never reuse old clamps when replacing the boot, as they are already deformed and will not provide a proper seal.
