Installing

Installation is reverse of removal, noting the following:

Remove any paint residue and/or corrosion in threads/splines of outer joint.

Vehicles with all wheel drive:

  Caution

• This ensures that the stub shaft circlip engages in the differential bevel gear correctly.
• This also prevents leaks.

  Note

Never use a hammer or mallet!

- Tap on the front side of the stub shaft using a plastic mallet.

Continuation for all vehicles

- Install the new circlip into the stub shaft groove on the transmission.

- Lightly grease the stub shaft splines with Universal Grease. Refer to the Parts Catalog.

- Bring outer and inner splines of the transmission and CV joint into engagement.

- Grab the drive axle by hand and push it into the CV joint up to the stop.

- Now push the CV joint with one jerk onto the transmission stub shaft.

- Make sure the CV joint is seated securely, to do this pull the CV joint against the resistance of the securing ring.

  Caution

When checking, only pull on the CV joint piece and not on the drive axle.

- Remove the Tensioning Strap -T10038-.

- Install the outer joint as far as possible into the wheel hub splines.

- Attach the ball joint to the control arm -arrows-.

  Note

Make sure the ball joint boot is not damaged or twisted.

- Tighten the driveshaft to wheel hub threaded connection. Refer to → Chapter "Drive Axle Threaded Connection, Loosening and Tightening".

- Install the front wheel. Refer to → Chapter "Wheels and Tires".

- On vehicles with electronically controlled damping, perform the function "Adapt the control position" with the Vehicle Diagnosis Tester.

- If the control position was reprogrammed and if the vehicle has lane assist, then it will then be necessary to calibrate the driver assistance systems front camera. Refer to → Chapter "Driver Assistance Systems Front Camera, Calibrating".

- On vehicles with level control system sensor, perform headlamp basic setting. Refer to → Electrical Equipment; Rep. Gr.94; Headlamp, Adjusting.
