Wheel Bearing Adjustment
Wheel bearings should be adjusted at regular intervals
using the following procedure:
Wheel End Seal
WARNING: Never work un-
der a vehicle supported by
only a jack. Always support
vehicle with stands. Block
the wheels and make sure
the vehicle will not roll be-
fore releasing the brakes
Important:
Wheel end seals can be easily damaged during handling. Leave the seal in its package until installation to
prevent damage or contamination.
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.
Caution:
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.
4. 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.
IMPORTANT: Always use the seal installation tool specified by the seal manufacturer. Using an improper tool

type wheel nut system and is not designed to bear against the inner nut.
