Differential Seals
WARNING: This page is about a different car, the 2024 Ford Transit-350 HD, 2024 Ford Transit-350, 2024 Ford Transit-250, and 2024 Ford Transit-150. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
When installing shafts, do not allow splines to contact seals during installation or damage to the seals may occur.
The front axle fluid level is above halfshaft. Top-off the fluid level after replacing either differential seal. The seals are one time use and should be replaced whenever the RH halfshaft is removed. Halfshaft pilot bearing housing 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.
