8. Install the differential side bearings by performing the following steps: 1. In order to protect the differential case, install the J 8107-3 in the case on the side opposite the bearing installation. See Special Tools. 2. Install the J 29710 and the J 8092 onto the differential case bearing. 3. Drive the bearing onto the case using the J 29710 and the J 8092 . BEARINGS INSPECTION Carefully and thoroughly inspect all drive unit parts before assembly. Thorough inspection of the Lubricate the bearings with axle lubricant. Inspect the bearings for smooth rotation. Inspect the bearing rollers for wear. Inspect the bearing cups for wear, cracks, brinelling, and scoring. DIFFERENTIAL INSPECTION Check the pinion gear shaft for unusual wear. Check the pinion and the side gear teeth for wear, cracks, scoring and spalling. Check the thrust washers for wear. Check the fit of the side gears in the differential case and on the axle shafts. Check the differential case for cracks and scoring and replace all of the worn parts as PINION AND RING GEAR INSPECTION Ring and pinion gears are matched sets. When replacement of one or the other is necessary, both Check the pinion and ring gear teeth for cracking, chipping, scoring, or excessive wear. Check the pinion gear splines for wear. Check the pinion flange/yoke splines for wear. Check the fit of the pinion gear splines on the pinion flange/yoke. IMPORTANT: The differential bearings and the bearing cups are matched sets. Replace both the bearing and the cup when either part
