At front bumper of vehicle, use measuring tape to determine center of vehicle.

Place a vertical mark on bumper at center of vehicle.

Drive up to a light-colored wall with both front lifting brackets of bumper almost touching wall and bumper parallel to

wall. Front wheels must be facing straight ahead.

Transfer vertical mark on bumper to wall.

Back up vehicle in a STRAIGHT line away from wall until vehicle is 25 ft (7.6 m) from wall. Apply parking brake and

shut down engine (TM 9-2320-312-10).

Extend mark on wall upward approximately 36 in (91.4 cm) and also downward to floor. This line is vehicle's center-

line.
