Replacement of lubricant in hinges

1. To remove a half shaft with two hinges.
2. After designation of provision of a half shaft of rather internal part of the hinge and a metal cover of rather external part of the hinge to take the hinge from the protection cover and to disconnect it from a half shaft.
3. To clear the hinge and to check degree of wear of balls and guides. To put lubricant in the hinge (see rice. Driving hinge): in space(s) of 10-15 g and in space (V) of 65-70 g in case of the two-layer protection cover and about 85 g – in case of the three-layer protection cover.
4. To install the hinge on a half shaft and to fix the protection cover. In case of need it is necessary to put on the new protection cover, paying attention to that lubricant did not get in it.
5. To establish a metal casing according to earlier executed designations and to provide its tightness in hinges.
6. To establish a half shaft.

Consolidation of hinges

In case of a lubricant performance on the surface of the hinge from under a metal casing it is necessary to arrive as follows.

1. To remove a half shaft together with two hinges, previously having designated its situation concerning elements to which it was connected.
2. To take the hinge from a metal casing and to disconnect it from a half shaft.
3. After careful cleaning of a surface of the hinge and a metal casing to apply on A surfaces (see rice. A surface for putting the pressurizing paste) the pressurizing paste.


To apply exclusively not hardening pastes and to apply them so that it was possible to tighten bolts evenly.

4. To connect the hinge to a half shaft and to install the protection cover.


The driveshaft of the car is connected to a secondary shaft of the transmission the elastic hinge. The flange on secondary to a shaft of the transmission is a component of this hinge.

Removal and installation of the elastic hinge

1. Extraction of the elastic hinge demands blocking of bolts with heads like Torx.
2. Before installation of the elastic hinge it is necessary to check whether bolts with heads like Torx the moment of 80 Nanometers are tightened.


If these bolts are turned, it is necessary to cover their carving with Loctite 270 glue.

3. To apply lubricant on the washers located on both parties of a flange so that not to allow them to be turned in the course of tightening new (at each installation of the hinge) nuts by the moment of 75 Nanometers.
4. To check a condition of rubber dampers In the elastic hinge (see rice. Elastic hinge).
5. If rubber dampers are erose or have cracks, then it is necessary to replace the driveshaft together with the hinge. It is impossible to replace only the hinge as the hinge and a shaft are balanced together.


Small cracks on the forward surface of the hinge do not mean obligation of its replacement yet.

Other information concerning a technical characteristic, adjustment and repair of the driveshaft and the back bridge is provided in section 7.
