A so-called triaxial joint is mounted on the drive shaft on the gearbox side «tripod», which can move on the internal wedge-new slots. The outer CV joint of the clutch is rigid, not displaced and depends on the type of engine. Nut of fastening of a power shaft (hubs) tightened with a certain moment, and then turned 60°. After tightening the nut, it is fixed with a slotted lock washer and cotter pin. Due to the significant tightening torque, special care must be taken when loosening the hub nut. If the car is installed on the goats.
Removing
Due to the fact that the oil seals that seal the holes into which the drive shaft shanks are inserted will need to be replaced with new ones before installing the shafts, an appropriate mandrel will be required to press the oil seals. When installing the shaft shank into the stuffing box, you should use the protective guides, which are sometimes included in the scope of delivery of the stuffing boxes.
When dismantling the drive shaft, other parts will also be disconnected. Therefore, it is necessary to prepare in advance a new hub nut, a new nut of the ball joint pin of the tie rod end, with which the rod is connected to the transverse arm, as well as a new nut for the coupling bolt of the suspension strut to the steering knuckle.
1. Apply the parking brake and engage first gear.
2. Loosen the wheel nuts without lifting the vehicle.
3. Loosen the hub nut using an appropriate socket, after removing the slotted lock washer and cotter pin from the hub nut. The hub nut can still be unscrewed (see illustration).
7.3 Loosen the hub nut
1- Nut
2-Splint
3- Slotted lock washer
4- Stop
4. Raise the vehicle and jack it up. The wheel can not be removed from the hub. If the hub nut is unscrewed on a car already mounted on the gantry, then the hub must be restrained from turning with an appropriate stop (see illustration 7.3). The stop handle must be on the floor.
5. Remove the drain plug on the transmission and drain approximately one liter of transmission oil into a suitable, clean container. The gearbox oil can be completely drained. Subsequently, oil will not flow out through the holes where the drive shaft shanks are inserted.
If the car is equipped with ABS, then disconnect the ABS sensor mounted on the steering knuckle so as not to damage it during the removal of the shafts.
6. Turn away nuts of coupling bolts by which an amortization rack is fixed on a rotary fist and pull out bolts. To do this, press the steering knuckle down to release the rack (see illustration). Before removing the bolts, mark which side the bolts are inserted from. Before loosening the tie bolt nuts and detaching the strut, make sure the vehicle is firmly on the trestle.
7.6 Fastening the suspension strut to the steering knuckle
1 - nuts of coupling bolts of fastening of an amortization rack to a rotary fist
2 - suspension strut
Attention! When disconnecting the shock absorber from the steering knuckle, do not damage the protective corrugated cover of the CV joint. It is recommended to wrap the CV joint covers with thick rags.
7. Give a rotary fist in the outer side, and a power shaft - in internal and thus take a shank of a power shaft from a nave. It is possible that the fit of the shaft shank in the hub will be tight enough and a hammer will be needed (plastic or metal), as well as a punch or soft metal roller to knock off the shank.
After removing the shaft from the hub, secure it with wire to the body so that it does not sag and under its own weight does not damage the hole in the gearbox.

8. Remove the inner CV joint shank from the transmission, keeping the drive shaft centered.
Drive shaft with thrust bearing
9. Loosen the nuts of the support bearing bolts and turn the bolt heads a quarter of a turn. This releases the outer ring of the support bearing (see illustration).
7.9 Remove the nuts 1 of the bolts securing the drive shaft support bearing. Turn the bolts a quarter of a turn past the heads on the bottom of the bearing housing
10. Hold the outer end of the drive shaft and pull it up until the inner end is out of the mounting block. After releasing the drive shaft, remove the dust ring from the inner end of the shaft.
11. Remove the oil seal from the hole on the gearbox into which the shank of the inner CV joint is inserted. The oil seal can be removed, with care, using a screwdriver. The oil seal must be replaced with a new one even if its condition is quite good.
