Wheel alignment
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2005 Porsche 911, 2004 Porsche 911, 2003 Porsche 911, 2002 Porsche 911, and 2001 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Only check or adjust wheel-alignment values when prescribed preconditions are met (GENERAL PROCEDURE FOR WHEEL ALIGNMENT
).
If the vehicle is measured front and rear, check and adjust the rear axle first. Nominal values are given on ADJUSTING VALUES FOR SUSPENSION ALIGNMENT - 911 CARRERA 4S . After adjustment, tighten the appropriate screwed connections with the prescribed tightening torque. See appropriate tables in FRONT WHEEL SUSPENSION, DRIVE SHAFTS and REAR WHEEL SUSPENSION, AXLE SHAFT .
The steering angle sensor must be calibrated if the previous wheel alignment values (on rear and/or front axle) for vehicles with PSM were changed!
CAUTION:
Malfunctions in the PSM control range if the steering angle sensor is not calibrated or is calibrated incorrectly.
- Calibrate the steering angle sensor with the wheels in straight-ahead position.
