Front axle
The design of the cross-axle differential of the front axle
1 - Driven gear of the main gear; 2 - Tapered roller bearings; 3 - Differential box; 4 - Side gears; 5 - Cross; 6 - Satellites; 7 - Spherical washers
1. Remove differential complete with final drive gear (see Section Removal and installation of assemblies of cross-axle differentials with driven gears of main gears).
2. Turn out fixing bolts and remove a conducted gear wheel (1).
3. Using a suitable puller, remove the tapered roller bearings (2).
4. Remove the cover from the differential box (3), - mark the position of the spherical washers, gears and crosses relative to each other and relative to the box. Also mark the position of the lid relative to the box.
5. Remove one of the side gears (4) with adjusting washer.
6. Remove cross assembly (5) with satellites (6).
7. Remove satellites (6) with spherical washers (7).
8. Remove the second side gear (4).
9. Thoroughly wipe the removed components, replace defective parts.
10. Installation is carried out in the reverse order - the shims must be turned with grooves to the side gears. Follow the correct alignment of the installation marks applied during the dismantling process. Before installing tapered bearings, check the resistance of the side gear to turning, - if necessary, select replaceable shims.
Note. Before pressing, the bearings should be heated to a temperature of about 80°C, - the bearings should be seated close to the differential gears.
Rear axle
The design of the cross-axle differential of the rear axle
1 - Driven gear of the main gear; 2, 12 - Tapered roller bearings; 3 - Differential box; 4 - Side gears; 5 - Cross; 6 - Satellites; 7 - Spherical washers; 8, 11 - Bolts; 9 - Thrust washers; 10 - Lid
1. Remove differential complete with final drive gear (see Section Removal and installation of assemblies of cross-axle differentials with driven gears of main gears).
2. Using a suitable puller, remove the tapered roller bearing (2) (driven gear side).
3. Turn out fixing bolts and remove from a box (3) driven gear (1).
4. Using a suitable puller, remove the tapered roller bearing (12) (from the side of the box).
5. Having previously marked the installation position, separate from the box (3) cover (10).
6. Remove the first side gear (4) with thrust washer (9).
7. Remove cross (5) with satellites (6) and spherical washers (7).
8. Remove the second side gear (4) with puck (9).
9. Thoroughly wipe the removed components, replace defective parts.
10. Installation is carried out in the reverse order - the shims must be turned with grooves to the side gears. Follow the correct alignment of the installation marks applied during the dismantling process. Check differential rotation resistance before installing tapered bearings (before pressing on, the conical bearings should be heated to a temperature of about 80°C, - the bearings should be seated close to the differential gears).
Note. A thinner shim should be installed on the side of the driven gear in order to provide sufficient engagement play.
