Drive axle shafts
Replacing the grease in the joints
1. Remove the half shaft with two joints.
2. After marking the position of the axle shaft relative to the inner part of the joint and the metal cover relative to the outer part of the joint, remove the joint from the protective casing and disconnect it from the axle shaft.
3. Clean the joint and check the degree of wear of the balls and guides. Put grease inside the joint (see Fig. Drive joint): in space (A) 10-15 g and in space (B) 65-70 g in the case of a two-layer protective casing and about 85 g in the case of a three-layer protective casing.
4. Install the joint on the axle shaft and secure the protective cover. If necessary, put on a new protective cover, paying attention to the fact that no grease gets inside it.
5. Install the metal casing in accordance with the previously made markings and ensure its tightness in the hinges.
6. Install the axle shaft.
Sealing of hinges
If grease appears on the surface of the hinge from under the metal casing, proceed as follows.
1. Remove the axle shaft together with the two joints, having first marked its position relative to the elements to which it was connected.
2. Remove the joint from the metal housing and disconnect it from the axle shaft.
3. After thoroughly cleaning the surface of the hinge and the metal casing, apply sealing paste to surfaces A (see Fig. Surface for applying sealing paste).
Caution! Use only non-hardening pastes and apply them in such a way that the bolts can be tightened evenly.
4. Connect the joint to the axle shaft and install the protective cover.
Cardan shaft
The cardan shaft of the car is connected to the secondary shaft of the gearbox by an elastic hinge. The flange on the secondary shaft of the gearbox is an integral part of this hinge.
Removal and installation the elastic joint
1. Removing the flexible joint requires locking Torx head bolts.
2. Before installing the flexible joint, check that the Torx head bolts are tightened to 80 Nm.
Caution: If these bolts turn, coat the threads with Loctite 270.
3. Apply grease to the washers located on both sides of the flange so as to prevent them from turning during the tightening of new nuts (at each installation of the joint) to a torque of 75 Nm.
4. Check the condition of the rubber dampers in the elastic joint (see Fig. Elastic joint).
5. If the rubber dampers are chipped or cracked, the driveshaft and joint should be replaced. The joint alone cannot be replaced, as the joint and shaft are balanced together.
Attention! Small cracks on the front surface of the hinge do not necessarily mean that it needs to be replaced.
