Differential Seals
NOTICE:
When installing shafts, do not allow splines to contact seals during installation or damage to the seals may occur.
Halfshaft
seals are susceptible to the same types of damage as drive pinion seals
if incorrectly installed. The seal bore must be clean and the lip
handled carefully to avoid cutting or tearing it. The seal journal
surface must be free of nicks, gouges and rough surface texture.
For information on differential seals,
REFER to: Rear Halfshaft Seal (205-02 Rear Drive Axle/Differential, Removal and Installation).
Removal
NOTICE:
Never pick up or hold the halfshaft by only the inner or outer CV joint. Damage to the CV joint will occur.
NOTICE:
Never use a hammer to remove or install the halfshafts...
