	Check and adjust
1	Perform wheel alignment check	Model 460 Model 461 (except 461.339) Model 463 up to model year 2019	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). Axle toe-in (total)	*BE33.25-P-1003-01A
6	Tighten bolts of hose clamps (4) at tie rod (3)	Bolt, clamp to tie rod	*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	Model 460, 461 (except 461.339) Model 463 up to model year 2019 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: ↓.

9	Tighten jam nuts (2) or hose clamps (8) on drag link (1)	Bolt, hose clamp to drag link	*BA46.40-P-1004-04B
		Lock nut to drag link	*BA46.40-P-1005-04B
10	Measure wheel angle and adjust if necessary	Model 460, 461 (except 461.339) Model 463 as of model year 2013 up to model year 2019 The measurement must not be performed 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 (except 461.339) with steering gear 765.5 Model 463 with steering gear 765.5 up to model year 2019 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).
