Grease evident at the front lower ball joint bellows
Transaction No.: 2068455/2
Customer statement / workshop findings
Grease evident on or around the front axle lower ball joint bellows
In the event the symptom is as described, the operative should carry out the instructions within the Measure section
Technical background
During service work and/or other repairs, a loss of grease can be detected from the front axle lower ball joint on one or both lower ball joint
bellows
Production change
Not applicable
Measure
Findings performed on supposedly damaged components have shown that they were of good quality, no damage was found
to the ball joint bellows which could of resulted in the leak
Grease may leak during the initial assembly of the front lower levers. This due to a maximum deflection of the conical spigot before the lower
lever is assembled into the wheel carrier. Over the service life, additional foreign bodies can collect in the corresponding area and stick to the
excess grease, which can then be distributed over a larger area
If there is no customer complaint about noises (rattling, pinching, creaking) from the area of the front axle and the lower levers have clearance,
the operative must remove any excess grease and check the ball joint and bellows for damage
If the ball joint/bellows is not damaged, the lower lever does not need to be replaced
The level of grease on or around the lower ball joint boot/wheel bearing housing (Figures 1,2 and 3) is deemed as a normal characteristic

If the ball joint is worn/damaged or the ball joint bellows is split/damaged (as shown in Figures 4 and 5) the lower front lever
must be replaced – Refer to Rep.Gr 40
IMPORTANT: Prior to replacing the lower lever the operative MUST raise a Technical DISS query requesting permission to
replace the front lower lever
