Half-shaft with constant velocity joint: repairs Grease the joints.   Note t  Quantity of grease for vehicles up to 48 kW: for the constant velocity joint exterior and interior, apply 90 grams of -G 000 603- to each one. t  Quantity of grease for vehicles of 55 kilowatts and more: exterior constant velocity joint 110 g and interior 120 g of -G 000 603-. t  Grease distribution for the exterior constant velocity joint: introduce half of the grease into the joint; the other half should be distributed evenly over the dust guard. t  Grease distribution for the interior constant velocity joint: introduce half of the grease into the joint; the other half should be distributed evenly in the dust guard. t  When replacing the dust guard, if necessary, regrease the joint.

Removing the exterior constant velocity joint –  Release from the complete half-shaft using a strong blow with a lightweight mallet.

Inner constant velocity joint: detach   Note t  Firstly release the protection for the constant velocity joint using a punch. t  Lock the ball hub.

Inner constant velocity joint: insertion –  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) should point to the support collar of the complete half shaft.

Installation position of the joint dust guard on the left hand side articulated half shaft Measurement -a- = 1 visible groove

Installation position of the joint dust guard on the right hand side articulated half shaft Measurement -a- = 1 visible groove   Note Does not include attachment clamp.

Tension of the interior and exterior joint clamps –  Connect the pliers -T20072- as shown in the diagram. 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 dustguard (in comparison with the rubber) and of the stainless steel clamp required, this may only be tightened using pliers -T20072-. t  Tightening torque: 25 Nm. t  Use a torque wrench with a range between 5 and 50 Nm (for example -SAT 8010-). t  Ensure that the thread of the pliers spindle turns smoothly. If necessary lubricate using grease -MoS2-. t  If the screw thread is difficult, when it is dirty, for example, the force necessary to put the clamp under pressure using the prescribed torque cannot be achieved.

Ventilation for constant velocity joint dustguard The dustguard for the constant velocity joint usually contracts when attached to the joint. A vacuum is produced in the dust guard so that while the vehicle is moving, an inward fold is produced -arrow-. Therefore, following fitting, the dustguard must be ventilated through the small hole to establish the pressure compensation.

Removing and fitting the dampening device Installation position → Fig.   Note t  Only replace the dampening device when the articulated half-shaft is removed. t  Before tapping the dampening device, protect the shaft paint work. t  To avoid axial movement apply sufficient glue to the interior diameter.
