32 00 ... Troubleshooting on front axle (wheel / chassis alignment check)
WARNING: This page is about a different car, the 2005 BMW 645Ci and 2004 BMW 645Ci. However, it is still accessible from the selected car via links, so may be relevant.
Substandard roadholding, atypical noises, tyres worn on one side and toe-in/camber values which deviate from the nominal value are all indicators of damage to the suspension caused by road traffic accidents or similar impacts.
To carry out proper repairs, you must follow the procedure set out in the troubleshooting table below depending on the condition of the vehicle in question.
Also comply with the guidelines for repairs to the power steering gear necessitated by an accident.
NOTE:
If after chassis/suspension components have been replaced adjustment of camber/track alignment is not possible, the vehicle must be placed on the straightening bench
REPLACED ADJUSTMENT OF CAMBER/TRACK
| Fault | Cause | Remedy |
|---|---|---|
| Toe deviation | Tie rod end worn | Replace tie rod end |
| Tie rod bent | Replace tie rod | |
| Rubber mount or ball joint of control arm faulty | Replace control arms | |
| Rubber mount or ball joint/guide joint of tension strut faulty | Replace rubber mount or guide joint/both tension struts | |
| Camber deviation | Rubber mount or ball joint of control arm faulty | Replace control arms |
| Control arm deformed | Replace control arms | |
| Rubber mount or ball joint/guide joint of tension strut faulty | Replace rubber mount or guide joint/both tension struts | |
| Tension strut deformed | Replace both tension struts | |
| Spring strut/piston rod of shock absorber deformed | Replace front spring strut | |
| Ride height between driver's and passenger sides different | Check load, correct if necessary | |
| Replace coil spring | ||
| Front axle carrier deformed | Replace front axle carrier | |
| Caster deviation
NOTE:
Caster is defined by design and cannot be adjusted

Rubber mount or ball joint of control arm faulty | Replace control arms |
| Control arm deformed | Replace control arms | |
| Rubber mount or ball joint/guide joint of tension strut faulty | Replace rubber mount or guide joint/both tension struts | |
| Tension strut deformed | Replace both tension struts | |
| Spring strut/piston rod of shock absorber deformed | Replace front spring strut | |
| Front axle carrier deformed | Replace front axle carrier | |
| Ride height between driver's and passenger sides different | Check load, correct if necessary | |
| Air spring strut: Carry out rideheight calibration | ||
| Check coil springs, replace if necessary | ||
| Toe-difference angle deviation Prerequisite: camber and caster are correct | Tie rods not adjusted uniformly | Adjust toe on left and right sides to same value |
| Wheel-offset deviation Prerequisite: front wheels have equal single toe to geometrical axis | Front axle carrier deformed | Replace front axle carrier |
| Control arm deformed | Replace control arms | |
| Tension strut deformed | Replace both tension struts |
