Removing the interior constant velocity joint   Note t  Separate the dust guard with a punch t  Secure the ball hub.

Fit the inner constant velocity joint –  Insert the constant velocity joint up to the limit. –  Insert the securing ring.   Note The bevel of the interior diameter of the ball hub (cogged) must face the support collar of the driveshaft.

Tighten the clamp of the inner 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 clamp by turning the spindle 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: 20 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.
