Filling the exterior constant velocity joint with grease: Total amount of grease: 180 g of lubricating grease -G 000 603- t  Insert approx. 90 g of grease into the outer joint through the inner gears of the ball hub. t  Spread approx. 90 g on the inside of the seal. t  If the dust guard is replaced, the seal may need to be re-greased. Greasing the tripod joint: Total amount of grease: 130 g of lubricating grease -G 000 603- t  Insert approx. 70 g of grease into the casing of the tripod joint. t  Spread approx. 60 g of grease on the dust guard. t  If the dust guard is replaced, the joint may need to be re-greased.

Removing the exterior constant velocity joint –  Secure the driveshaft in workshop vice with the claws. –  Push the dust guard backwards. –  Remove the constant velocity joint from the driveshaft using an awl -A-. The awl must be positioned exactly onto the star of the seal. Position the seal –  Insert into the driveshaft using a plastic hammer, until the safety ring fits into position.

Tightening of the large clamp of the outer constant velocity joint –  To do so, position the pliers -V.A.G 1682- as shown in the figure. Ensure that the edges of the tool fit into the corners -arrows B- of the clamp. –  Tense the clip by turning the screw using the torque wrench taking special care not to incline the pliers during the operation.   Note t  Given the firmness of the material (in comparison with the rubber) of the union dust guard, 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. -V.A.G 1331-). t  Check that the spindle thread -A- of the pliers can be tightened without forcing. Apply grease -MOS 2-, if necessary. t  If the thread does not turn easily (due to dirt, for example), it will not be possible to tighten the clamp sufficiently when applying the specified torque.

Tighten the small clamp of the outer joint

Tighten the large and small clamps of the tripod joint The figure shows how the small clamp of the tripod joint must be tightened. The large clamp is also tightened with the pliers -V.A.G 1275-.

Remove the tripod from the driveshaft

Fit the tripod onto the driveshaft This operation only refers to driveshafts with conical ends -arrow-.

Fit the tripod onto the driveshaft This operation only refers to driveshafts with cylindrical ends -arrow-.

Assembly position of the counterweight Note the assembly position of the counterweight when fitting it. The measurement -a- is measured from the front end of the counterweight up to the edge of the casing. a -  20 ± 1 mm 1 -  Counterweight 2 -  Joint casing
