CV joints are protected from moisture and dust by covers (anthers), which need to be checked regularly. Damaged or cracked boots should be replaced immediately, because moisture and dust will destroy the CV joint.
Attention! It is not allowed to move the car after removing the drive shaft. This can cause damage to the hub bearing due to lack of axial load. If it is necessary to move the car, instead of the drive shaft, you can install the shank of the outer CV joint in the hub and fix it with an M14 or M16 bolt with a tightening torque of 115 or 190 Nm.
Withdrawal
Attention! The procedure for removing and installing the drive shaft is shown using the example of the front axle shaft.
1. Loosen the bolt securing the drive shaft shank to the hub (see illustration 6.0).
Attention! When unscrewing the hub bolt, the car must be on wheels.
2. Mark with paint the position of the front wheel on the hub, the drive shaft of which will be dismantled. This will allow the assembly to set the balanced wheel in its original position.
3. Loosen the wheel bolts.
4. Jack up the front of the car, install it on the jack stands and, having unscrewed the fastening bolts, remove the wheel.
5. Completely unscrew a bolt of fastening of a power shaft in a nave.
6. Unscrew the bolts that secure the inner CV joint 1 to the gearbox (see arrows in illustration).
6.6. Unscrew the bolts that secure the inner CV joint 1 to the gearbox (see arrows)
7. Release the ABS sensor wire from the holder, unscrew the mounting bolt and disconnect the ABS sensor from the steering knuckle
8. Disconnect both top levers from a rotary fist, having unscrewed a coupling bolt.
9. Move the steering knuckle to the side, remove the shank of the outer CV joint from the hub and remove the drive shaft.
Installation
10. Fix a power shaft on a transmission and in a nave.
11. Tighten bolts of fastening of a power shaft to a transmission, acting in a cross order. Bolt tightening torques:
- bolts M8 - 40 Nm;
- bolts M10 - 70 Nm.
12. Retract the drive shaft shank into the hub by screwing in and tightening the new hub bolt. The final tightening of the hub bolt is carried out after the vehicle is mounted on the wheels.
13. Establish both top levers on a rotary fist, having pressed fingers of their spherical support into the corresponding openings, and tighten a coupling bolt.
14. Reinstall the ABS sensor on the steering knuckle, and fix its wire in the holder on the caliper.
15. Lower the car on wheels and tighten a bolt of fastening of a shank of a power shaft in a nave. Have an assistant depress the brake pedal and hold it in that position. Tighten the M14 bolt to 115 Nm. If the drive shaft is fastened in the hub with an M16 bolt, then it is tightened at this stage with a force of 190 Nm. Then tighten the bolt with a wrench by 180°.
16. Establish a forward wheel on a nave so that the labels put before removal coincided. Lubricate the wheel seat on the hub with a thin coat of bearing grease before installing the wheel. Do not grease wheel bolts. Replace rusted wheel bolts with new ones and screw them in.
17. Tighten the wheel bolts in a cross pattern to 120 Nm.
Attention! If a bulkhead of the CV joint was carried out, then during assembly, grease is filled into the CV joint and into its case.
