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.
