Inner CV Joint Boot Clamp, Installing
-
Use the (VAG 1682) as shown in the illustration. Be sure that edges of the (VAG 1682) are seated in the corners - arrows B - of the clamp.
-
Tighten the clamp by turning the spindle using a torque wrench - C - (do not tilt the (VAG 1682)).
‹› A stainless steel clamp must be used due to the hardness of the CV joint boot material (compared to rubber). This clamp can only be tensioned
using the (VAG 1682).
‹› Tightening specification: 20 Nm.
‹› Use a torque wrench with 5 to 50 Nm range (for example, (VAG 1331)).
‹› Make sure the spindle threads - A - on the (VAG 1682) move freely. Grease with MoS2 grease if necessary.
‹› If they do not move freely, due to dirt in the threads, the required clamp tension will not be achieved at the specified torque.
Inner CV Joint, Checking
In order to replace grease in case of strong contamination or if the journal surfaces and ball bearing must be checked for wear and damage the CV
joint must be disassembled.
Disassembling
‹› Ball hub and CV joint are paired and should be identified before removal. Do not interchange cage allocation.
-
Swing the ball hub and ball cage.
