Loosen nut "1" of tie rod end pin "2" until it is flush with the pin thread. If necessary, hold it from turning while loosening.
To protect the thread, leave the nut on the pin screwed on for several turns. Press out the end of the transverse steering rod from the hub bearing housing using the ball joint puller "T40010 A". Then unscrew the nut.
Ensure that both arms of the puller lever are parallel to each other at the moment of maximum force application; correct the position if necessary. Disconnect bolt connection 1.
To remove bolt "1", depending on the side of the vehicle, turn the steering gear all the way to the left or right. Remove the control arm from the mount and move it back. Unscrew the ball joint pin nut so that it is flush with the joint pin thread. If necessary, hold it from turning when loosening. Press out the suspension arm joint pin using the ball joint puller "T40010 A" from the conical socket. Make sure that both arms of the puller lever are parallel to each other at the moment of maximum force application; correct the situation if necessary. Do not damage the joint boot! To avoid damaging the upper suspension arm joints, it is necessary, for example, to use the engine and gearbox lift "VAG 1383 A" to provide support for the hub bearing housing against the reverse travel of the shock absorbers. Unscrew the nut from the suspension arm joint pin. Remove the control arm.
Installation
Installation is carried out in the reverse order. In doing so, the tightening torques must be observed. The block "belts" have a limited working torsional range. Therefore, the wheel suspension bolt connections must only be tightened when the vehicle is in the unloaded position or in the standard suspension position. Raise the wheel support with the suspension in the static position on vehicles with coil springs. When tightening threaded connection "1", the support arm must be pressed against the inside of the vehicle. Remove any adhesive residue from the ball joint pin thread. On vehicles with automatic transmission and headlight range control, perform the basic headlight setting. After removing and installing the vehicle level sensor or loosening the rods on vehicles with electronic damping control, the standard suspension position must be readjusted. After re-adapting the adjustment position on vehicles with lane assist, the lane assist control unit "J759" must be recalibrated. Tighten the wheel. The wheel alignment angles must be adjusted.
