DESCRIPTION AND OPERATION Lubrication
The differential, swivel pin housing and wheel hubs
are individually lubricated and separated by oil seals
(7) and (8), see J6267A, to prevent oil transfer across
the axle when the vehicle is traversing steep inclines.
The wheel bearings are lubricated with grease and the
swivel housing and differential with oil. On later
vehicles, identified by having only a filler plug in the
swivel housing, grease is used to lubricate the
housing...

FAULT DIAGNOSIS FAULT DIAGNOSIS
Complaint - Oil leaks
An external leak of lubrication can be caused by a
faulty internal seal. For example, if the seals which
separate the differential from the swivel housings are
faulty and the vehicle is operating or parked on an
embankment, oil may leak across the axle leaving one
swivel with a high level and the opposite swivel and
differential lacking lubrication.
See’Description and Operation’for illustrations of oil
seal locations....
