• Lubricant loss that can affect differential operation
• Leakage around the rear pinion shaft seal surface

Installation Notes and Tips

Confirm the shaft diameter, outside diameter, and width against the removed seal before installation. Inspect the pinion yoke and sealing surface for wear, scoring, or corrosion, since surface damage can shorten seal life. Clean the housing bore and sealing area thoroughly so the nitrile lip seats evenly during assembly.
