Bearings Inspection
Differential Case Bearings InspectionImportant:
^ When replacing the worn or cracked bearings and the cups, replace the bearings in sets.
^ The low mileage bearings may have very small scratches and pits on the rollers and the bearing cups from the initial preload.
Do not replace a bearing for this reason.
1. Inspect the bearings for smooth rotation after oiling.
2. Inspect the bearing rollers for wear.
3. Inspect the bearing cups for these conditions:
^ Wear
^ Cracks
^ Brinelling Scoring
Differential Case and Gears Inspection
1. Inspect these components for excessive wear and/or fit:
^ The pinion gear shaft
^ The thrust washers
^ The differential case for wear, cracks and scoring
^ The fit of the pinion gear shaft in the differential case
^ The fit of the differential side gears in the differential case
^ The fit of the side gears on the axle shafts
2. Inspect the teeth of the pinion gears and the differential side gears for these conditions:
^ Wear
^ Cracks
^ Scoring
^ Spalling
3. Replace any worn or poor fitting components as necessary.
