Removing

Before starting work:

- Versions with coil springs: determine the curb weight position. Refer to → Chapter "Wheel Bearing in Curb Weight Position, Lifting Vehicles with Coil Spring".

- Vehicles with air suspension: determine the standard vehicle height. Refer to → Chapter "Wheel Bearing at Standard Vehicle Height, Lifting Vehicles with Air Suspension".

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

- Remove the noise insulations. Refer to → Body Exterior; Rep. Gr.66; Noise Insulation; Noise Insulation, Removing and Installing.

- To protect the threads remove the nut -arrow- on the joint pin tie rod head until it is flush with the threads of the joint pin.

  WARNING

Risk of injury from falling components!

When pressing off, the tie rod end loosens abruptly from the wheel bearing housing. Use, for example, the Engine and Gearbox Jack -VAS6931- to secure.

  Caution

There is a risk of damaging the ball joint puller.

Pay attention that both puller lever arms are parallel to each other when using greatest force.

- Remove the tie rod end with the Ball Joint Splitter -VAS251805- from the wheel bearing housing.
