IMPORTANT: Risk of damage!
In order to avoid damaging the front side panel during the "Max. steering lock" drive-in routine, make sure the pickups are removed from the quick-clamping holders/quick-clamping units during output and input alignment. In the process do not detach the connecting cable from the pickups or the rotary plates.

NOTE: After the drive-in routine, reconnect the pickups to the quick-clamping holders/quick-clamping units, align using the bubble levels and secure in place.

Perform input measurement in accordance with equipment manufacturer's instructions.
Compare specified values with actual values. See STEERING AND WHEEL ALIGNMENT - TECHNICAL DATA .

Only in event of customer complaint (e.g. poor driving performance):

IMPORTANT: Do not remove screws/bolts (front axle carrier to engine carrier / body).

Slacken all screws/bolts (front axle carrier to engine carrier / body) and then retighten to specified torque.

See 31 11 506 LOWERING/RAISING FRONT AXLE CARRIER (M3, UNIVERSAL LIFTER) ..

If necessary, adjust front axle and rear axle

IMPORTANT: Only on cars with Active Cruise Control:
Because the axis of motion is the reference for ACC adjustment, it is necessary after an adjustment of the rear axle which alters the axis of motion also to check the adjustment of the ACC sensor!
It is not necessary to check the ACC sensor after only one adjustment of the front axle!

Perform output measurement in accordance with equipment manufacturer's instructions.
Save and print out test record.
Carry out steering angle sensor adjustment/adjustment for active front steering . See 61 31 996 CARRYING OUT STEERING ANGLE SENSOR ADJUSTMENT .
Insert locking pins into both rotary and sliding plates
Remove chassis/wheel alignment system
Drive vehicle off lifting platform
If necessary, carry out adjustment of ACC sensor . See 66 31 001 ADJUSTING ACC SENSOR
