	Check and adjust
1	Perform a wheel alignment check		AR40.20-P-0200AC
2	Fasten bubble level in place to check the center position of the steering wheel
3	Undo jam nuts (2) or hose clamps (8) on drag link (1)	On some model designations the clamps (8) are fitted to the drag link (1) instead of the jam nuts (2).
4	Release hose clamps (4) on tie rod (3)
5	Adjust toe	Set track width by twisting the adjusting nut on the tie rod (3).	*BE33.25-P-1003-01A
6	Tighten bolts of hose clamps (4) at tie rod (3)		*BA46.40-P-1001-01D
7	Turn front wheels to straight-ahead position.
8	By turning the drag link (1) or adjusting nut on the drag link (1) move the steering wheel to the center position	The front wheels must remain in the straight-ahead position. Under some conditions on older vehicles the drag link (1) cannot be twisted, here to adjust the center position of the steering wheel the ball head of the drag link (1) must be removed at the pitman arm, see:↓

10	Measure wheel angle and adjust if necessary	The measurement must not be made when the engine is running, as otherwise the hydraulic limiter will prevent the mechanical limit stop from being reached. Before adjusting the hydraulic limiter make sure that the mechanical limit stop is within the specified tolerances.	AR40.20-P-0345AC
11	Check hydraulic limiter of steering gear and adjust if necessary	Model 460, 461, 463 with steering 765.5 Model 460, 461 with steering 760.2 After performing adjustment operations on the drag link (1) the center position of the steering gear may be displaced, for this reason the hydraulic limiter must always be checked.	AR46.25-P-3090F
12	Check straight-line stability during test drive	If the steering wheel is only slightly askance when driving straight ahead, this can be corrected by adjusting the drag link (1).
