3.36 CHECKING THE GREASED WHEEL HUBS FOR LEAKS
1. Check the wheel hubs for leaks.
Note:
If there are serious grease marks on the brake
disc side of the wheel hub, this could indicate
excessive use of assembly grease on new or
recently assembled wheel hubs.
On wheel hubs that have not been assembled
recently, serious grease marks could indicate a
leak in the seal (1). This means that the entire hub
unit must be replaced.
Serious oil leakage on the driven rear axle hubs
could indicate that the O-ring (2) is not sealing
correctly.
If there is an oil leak the hub unit should be
dismantled to remedy the problem.
