Inspect the satellites and the surface of their axle, the journals of the axle gears and their mounting holes in the differential box. Remove minor damage with 10-M40 grit sandpaper, and in case of serious damage, replace the parts with new ones.
Check the condition of the surface of the axle gear bearing washers. If even minor damage is detected, replace them. When replacing washers with new ones, select them according to thickness.
Inspect the bearings of the pinion gear and differential box. They should be free of wear, with smooth working surfaces. If there is the slightest doubt about their performance, replace the bearings. Poor condition of the bearings can be the cause of noise and seizing of the teeth. Check the crankcase and differential box for deformations or cracks. Replace them with new ones if necessary.
The dimensions of the main mating parts of the rear axle mechanisms and the limits of wear permitted during vehicle operation are given in Table 7.
