NOTE: The stub shaft seals must be replaced whenever the halfshafts are removed.
1. Remove the halfshaft assembly. For additional information, refer to Drive Axles, Bearings and Joints.
2. NOTE: If removing the stub shaft pilot bearing oil seal only, engage the tangs of the Bearing Remover on the stub shaft pilot bearing oil seal only.
Using the Slide Hammer and Bearing Remover, remove and discard the stub shaft pilot bearing and the stub shaft pilot bearing oil seal.
3. Inspect the seal journal for rust, nicks and scratches. Polish the seal journal surface with fine crocus cloth, if necessary.
4. Lubricate the new stub shaft pilot bearing with axle lubricant.
5. NOTE: Installation of the stub shaft pilot bearing or stub shaft oil seal without the correct tools can result in early bearing or seal failure. If the
stub shaft pilot bearing becomes cocked in the bore during installation, remove it and install a new one.
Place the stub shaft pilot bearing onto the Halfshaft Pilot Bearing Installer and Adapter.
6. Install the stub shaft pilot bearing into the rear axle housing bore.
7. NOTE: Do not disassemble the new oil seal.
NOTE: Use a tool like the Lisle LIS17850 to avoid interference with the suspension components.
Install the new seal onto a suitable installer.
8. NOTICE: Strike only the handle. Directly striking the installer tool will damage the seal.
Carefully align the stub shaft pilot bearing seal with the housing bore and install the stub shaft pilot bearing seal flush in the differential housing.
9. NOTE: If a feeler gauge of the specification shown in the illustration can be inserted between the stub shaft oil seal and the differential housing,
the stub shaft seal is not seated correctly. Remove the stub shaft oil seal and install a new stub shaft oil seal.
Make sure the stub shaft oil seal is correctly seated in the differential housing.
