Track Control Arm
Track Control Arm
Special tools, testers and auxiliary items required
• Engine/transmission jack (V.A.G 1383 A)
• Ball joint puller (T40010 A)
• Ring socket wrench (V.A.G 1332/10)
• Ring socket wrench (V.A.G 1332/7)
Removing
- Remove the wheel.
- Remove the noise insulation.
- Remove in vehicles with vehicle level sensor nut - 2 -.
- Disconnect the connectors - 3 -.
- Unscrew the nut - 1 - from the joint pin - 2 - on the tie rod end as far as required to make it flush with the threading on the joint pin. Counterhold it if you have to when loosening.
• Turn the nut a couple of turns on the pin to protect the threading.
- Use the (T40010 A) to force the tie rod end off of the wheel bearing housing. Next, remove the nut.
• Make sure that both lever arms on the puller are parallel to each other when you exert a great deal of force on them; adjust them so that they are parallel, if necessary.
- Disconnect the connectors - 1 -.
• To remove the bolt, - 1 - turn the steering gear completely to the left or right, depending on the side of the vehicle you are on.
- Remove the control arm and pivot it to the rear.
- Unscrew the nut from the joint pin on the ball joint just far enough to make it flush with the threading on the joint pin. Counterhold it if you have to when loosening.
- Use a (T40010 A) to force the joint pin on the control arm off of the conical seat.
• Make sure that both lever arms on the puller are parallel to each other when you exert a great deal of force on them; adjust them so that they are parallel, if necessary.
• Make sure not to damage the CV boot when doing this!
• The wheel bearing housing must be braced against too much rebound, e.g. by using the (V.A.G 1383 A) , so that the joints on the upper control arm are not damaged.
- Remove the nut(s) from the joint pin on the control arm.
- Remove the control arm.
Installing
Install in reverse order of removal. Pay attention to the following:
Tightening specifications, refer to => [ Track Control Arm, Ball Joint, Guide Link and Level Control System Sensor Assembly Overview ] Track Control Arm, Ball Joint, Guide Link and Level Control System Sensor Assembly Overview.
• Bonded rubber bushings have a limited range of rotation. Therefore, do not pull the threaded connections on the wheel suspension tightly until the vehicle is positioned in the curb weight or control position.
• Raise the wheel bearing in curb weight position on vehicles with coil springs. Refer to => [ Wheel Bearing, Lifting to Curb Weight Position ] Front Suspension.
• The control arm must be depressed toward the inside of the vehicle when tightening the threaded connection - 1 -.
- Remove the remaining adhesive still stuck to the threads on the pin from the control arm.
- Perform a headlamp basic setting on vehicles with automatic range control.
- The control position must be "retaught" if the vehicle level sensor has been removed or installed, or if the linkage rod has loosened, in vehicles equipped with electronic damping. Refer to => [ Control Position, Programming using VAS 5051B ] Testing and Inspection.
- The directional stabilization assistance control module (J759) must be re-calibrated if the control position has been "retaught" in vehicles equipped with lane assist. Refer to => [ Lane Assist Calibration Procedure ] Lane Assist Calibration Procedure.
- Tighten the front wheels.
- Axle alignment required; see table. Refer to => [ Wheel Alignment ] Wheel Alignment.
