WM 449503 Suspension alignment, complete

Rear axle

1. Prepare vehicle for checking and/or adjustment of wheel alignment values.
2. Place front wheels on rotary table and rear wheels on rotary / sliding plates.
3. Compress vehicle at front and rear axles by approximately 25 mm 2-3 times and allow it to spring back freely.

WARNING

Steering-angle sensor not calibrated or calibrated incorrectly

- Unexpected vehicle handling
- Steering-angle sensor does not function
- Malfunction in steering-angle sensor

-> After working on wheel suspension parts, when replacing the steering-angle sensor and after changing the wheel alignment values, calibrate the steering-angle sensor using PIWIS Tester II 9818.
-> Keep the front wheels in straight-ahead position on the measuring platform during calibration.
-> On vehicles with electromechanical steering, also re-teach the electric steering lock settings.
