Removing the exterior constant velocity joint –  Clamp drive shaft in vice using protective jaw covers. –  Fold back boot. –  Remove the constant velocity joint from the driveshaft using an awl -A-. The awl must be positioned exactly onto the star of the seal. Installing joint –  Drive a plastic hammer onto the shaft until the locking ring snaps in.

Driving off cover from inner joint –  Remove the securing ring. –  Remove both clamps and slide boot towards outer joint. –  Separate the dustguard with a punch.

Pressing off inner constant velocity joint Assembling

Installation position of the plate spring on the joint 1 -  Dished spring

Installation position of the plate spring and thrust ring on the exterior joint 1 -  Dished spring 2 -  Thrust washer

Pressing on inner constant velocity joint –  Press on joint as far as stop. –  Install retaining ring.

–  Apply sealing compound (allocation → parts catalogue) on the sealing surface of the cover. –  Apply a continuous strip of sealant, of Ø 2...3 mm, on the cleaned surface of the cover, avoiding the holes on the inside -arrow-.

–  Using bolts -arrows-, align new cover in relation to bolt holes. The alignment must be perfect, because it is not possible to align after fitting. –  Use a plastic hammer to fit the cover. –  Remove excess sealant.

Tension the clamp of the exterior constant velocity joint –  Apply clamp tensioner-V.A.G 1682- as shown in illustration. Ensure jaws of tensioner lie in corners -arrows B- of ears on O-type clip. –  Tighten clamp by turning spindle with a torque wrench (do not cant pliers).   Note t  Given the firmness of the material (in comparison with the rubber) of the union dustguard, a stainless steel clamp is required, this can only be tightened using the pliers -V.A.G 1682-. t  Tightening torque: 25 Nm t  Use a torque wrench -C- with a range between 5 and 50 Nm (e.g torque wrench -V.A.G 1331-). t  Check that the spindle thread -A- of the pliers is easily movable; apply grease if necessary. t  If the thread does not turn easily due to dirt, for example, it will not be possible to tension the clamp to the prescribed torque.
