Wheel End Seal
Remove and Overhaul Wheel End Seal
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.
Wheel end seals can be easily damaged during handling.
Leave the seal in its package until installation to
prevent damage or contamination.
1. Remove outer bearing and wheel.
2. Remove oil seal.
3. Remove inner bearing.
4. Remove old wear sleeve (2-piece design only) with a
ball peen hammer and discard.
Do not cut through the old wear sleeve. Damage to the
housing may result.
5. Inspect spindle journal and hub bore for scratches or
burrs. Recondition with an emery cloth as required.
Note: Deep gouges can be repaired by filling gouge with hard-
ening gasket cement and smoothing with emery cloth.
6. Clean hub cavity and bearing bores before reassem-
bly. Be sure to remove contaminants from all
recesses and corners.
7. Clean bearings thoroughly with solvent and examine
for damage. Replace damaged or worn bearings.
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.
