Differential Case Bearings Inspection

Important 

• 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 ups from the initial preload.

  Do not replace a bearing for this reason.

1. Inspect the bearing for smooth rotation after oiling.
2. Inspect the bearing rollers for wear.
3. Inspect the bearing cups for the following conditions:
   • Wear
   • Cracks
   • Brinelling
   • Scoring
