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.

Refer to 31 11 506 LOWERING/RAISING FRONT AXLE CARRIER .

If necessary, adjust front axle and rear axle . See 32 00 610 ADJUSTING TOE-IN AND CAMBER ON FRONT AXLE and 32 00 620 ADJUSTING REAR AXLE .
Perform output measurement in accordance with equipment manufacturer's instructions.
