The Instructions for Fig.1 apply only to stainless steel tensioning clamps!
Rubber CV boot are clamped on with V.A.G. 1275 pliers.





Fig. 1 Tighten clamp on outer joint
^ Apply VAG1 682 CV boot clamping pliers as shown in figure. Be sure that edges of clamping pliers are seated in corners (arrows -B-) of hose clamp.
^ Tighten hose clamp by turning spindle with a torque wrench (do not tilt clamping pliers).

Note:
^ Tightening torque: 20 Nm.
^ Use torque wrench with adjustment range from 5 to 50 Nm (e.g. V.A. G 1331).
^ Be sure thread of spindle in clamping pliers moves freely. Grease with MoS 2 grease, if necessary.
^ If it does not move freely, e.g. due to dirt in thread, the required clamp tension will not be achieved at the specified torque.





Fig. 2 Lower constant velocity joint at outside
^ Clamp drive axle in vice with protective pads.
^ Take off the big hose clamp and pull back CV boot
^ Using a hammer hit a copper or brass mandrel onto inner ring of constant velocity joint





Fig. 3 Venting CV boot
Only affects rubber CV boots
Installing CV boot can create a vacuum in joint
This vacuum pulls a fold inward when car is driven (arrow).
Therefore, note the following:
^ Before tightening hose clamp, raise CV boot to allow pressure to equalize.
