CLOSING SLOTS IN BALL JOINTS
As of September 1982, plastic sealing cord is used to close the slots for
the outer setting eccentrics of the front-axle ball joints of new cars. In
this way, dirt is prevented from penetrating the joint, making the
eccentric easier to operate when servicing.
If work has been carried out on the front axle, and especially after
realignment of the wheels, close the slots for the outer eccentrics with
permanently-elastic sealing material on all cars (arrows). The sealing
cord, part No. AKD 522.009, used to seal the 924 and 944 taillamps is
suitable for this application.
Before sealing, ensure that slots are dry and free of grease.
If eccentric does not move freely
(dirt in slot) we recommend
removal of the outer eccentric,
cleaning of the slot and spraying
with rust remover. Apply Optimoly
TA to sliding surface of eccentric
in adjustment area and reinstall
eccentric.
Important:
Never try to free eccentric by hitting ball joint. Impact may damage the
rubber cap.
If.the rubber cap of a ball joint is damaged, it is essential to replace
the joint. See also "Inspecting Protective Caps of Ball Joints of Control
Arms and Track Rods" (page 40 - 24).
