Front axle
Front Axle Differential Assembly Installation Details
1 - Lid; 2 - Mounting brackets; 3 - Assembly of the differential with the driven gear of the main transmission
Checking the value of the resistance of tapered bearings to rotation
Checking the clearance of the main gear engagement gears
1. Drain the oil from the axle housing (see Section Checking and adjusting the level/replacing oil in bridge assemblies).
2. Unscrew and remove the cover (1).
3. Remove both drive shaft assemblies with hinge housings (see Section Removal and installation front axle drive shafts).
4. Pre-marked (complete with adjusting washers and outer races), remove the mounting brackets (2).
5. Using a special device (460 589 05 31 00) unclamp the gearbox housing and remove the differential assembly with the driven gear of the main transmission (3) from it.
6. Thoroughly wipe the removed components, defective
7. Installation is carried out in reverse order.
Note: Do not use any sealants when installing the cover (1). Do not forget to check the values of the bearing resistance to rotation and the play in the engagement of the main gear gears (see illustrations above). Also evaluate the characteristics of the contact patches (see Section Checking the correct engagement of the main transmission gears). Make sure that the crankcase drain plug is tightened to the required torque.
Rear axle
Rear Axle Differential Assembly Installation Details
1 - Lid; 2 - Mounting brackets; 3 - Assembly of the differential with the driven gear of the main transmission; 4 - Adjusting rings; 5 - Outer races; 6 - Sealing gasket
The procedure is similar to that described above for the front axle differential, with an adjustment for the design of the latter (order of extraction of semi-axles).
