SUBJECT:
Rear Axle Seal Weepage Diagnosis

NOTE:
This bulletin applies to vehicles equipped with all wheel drive.
DISCUSSION:
Due to improper diagnosis, some rear differential seals are being replaced for what appears to be a seal leak. Grease is used to lubricate the seal during installation to the rear differential, after a period of time this grease may migrate to the surrounding housing and appear to look like an oil leak. Seals should not be replaced for this condition (Fig. 1).
Seals should only be replaced when it is determined that oil is migrating from the seal down the differential housing (Fig. 2).
