Special Instructions
Never work under a vehicle supported by only a jack. Always support vehicle with stands. Block the wheels and make sure
the vehicle will not roll before releasing the brakes.
Procedure - Wheel End Seal
1. Remove:
• The outer bearing and wheel.
• The inner bearing.
• The oil seal or grease retainer and discard.
• The old wear sleeve (2-piece design only) with a ball peen hammer and discard.
Wheel end seals can be easily damaged during handling. Leave the seal in its package until installation to prevent dam-
age or contamination.
Do not cut through the old wear sleeve. Damage to the housing may result.
2. Inspect:
• The spindle journal and hub bore for scratches or burns. Recondition with emery cloth as required.
Note: Deep gouges can be repaired by filling gouge with hardened gasket and smoothing with emery cloth.
3. Clean:
• The hub cavity and bearing bores before reassembly. Be sure to remove contaminants from all recesses and corners.
• The bearings thoroughly with solvent and examine for damage. Replace damaged or worn bearings.
• Before installation, lubricate with the same lubricant used in the axle sump.
• The inner bearing.
• The wheel seal following the directors provided by the seal supplier.
Always use the seal installation tool specified by the seal manufacturer. Using an improper tool can distort or damage
the seal and cause premature seal failure.
