3.38 CHECKING GREASED WHEEL HUBS FOR LEAKS
1.
Check the wheel hubs for leaks.
Note:
For maintenance-free wheel hubs:
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 were not assembled
recently, serious grease marks could
indicate a leak in the seal.

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.
