	Inspect
1	Test drive vehicle when received and determine actual condition
2	Raise the vehicle on lifting platform	Wheels freely suspended.
3	Detach engine compartment paneling at the bottom in the area of the steering	Vehicles with diesel engine only.	AR61.20-P-1105AB
4	Turn rack-and-pinion steering to center position	The marking on the cap (3) must align with the marking on the timing case (arrows).
5	Pull rubber plug out of the adjusting screw (6) of the play compensation
6	Mark adjusting screw (6) relative to the timing case
7	Open left bellows at clamp and push to side
8	Attach bracket and dial indicator above the adjusting screw (6) on the steering gear and adjust to zero point	Bracket	Fig 2
		Dial gage	Fig 3
		The zero position of the dial indicator should not be changed any more during the measurement.
9	Start the measurement of the play in the center position of the rack-and-pinion steering and repeat at 8 further points in steering wheel position 90°, 180°, 270° and 360° counterclockwise and clockwise	To rotate, push the socket wrench bit on the steering shaft splines.	Figure
		The play is determined by rotating the rack from stop to stop. The force input should be approx. 1.1 Nm at the stop. The maximum value minus the minimum value produces the play (z. B. +10- (-1) = 11, the play is 11/100 mm).
10	Remove holder with dial gauge from steering gear
11	Adjust the play at the narrowest point to 4 to 5/100 mm in the center position of the rack-and-pinion steering	The play is reduced by turning the adjusting screw (6). (1 mm on the circumference of the adjusting screw corresponds to approx. 1/100mm reduction in play).
12	Repeat steps 8 and 9
13	Attach left bellows
14	Press rubber plug into the adjusting screw (6)	Check rubber plug for damage and replace of the play compensation if necessary.
15	Install lower engine compartment paneling.	Vehicles with diesel engine only.	AR61.20-P-1105AB
16	Conduct a road test	Test drives should be carried out under approximately the same conditions. This applies particularly with regard to the speeds driven at.
