Warning | Risk of injury from being trapped in the swivel range of steered axles | Ensure that no persons or objects are in the swivel range of all steered axles when turning the steering wheel. Do not stand in the swivel range of the additional steering axle when the engine is running. | |
Danger | Risk of death caused by vehicle slipping or toppling off during lifting | Only lift vehicle at the lift support points specified by the vehicle manufacturer. | |

| Check | ||
1 | Move front wheels to straight-ahead position. | ||
2 | Position all steerable wheels centrally on the turntables. | ||
3 | Set scales of turn plates on 1st front axle to 0°. | ||
4 | Release counternuts (2) of stop screws (1) on both steering knuckles of 2nd front axle and screw stop screws (1) all the way in. | Only on model 932.3, 952.3, 964.23 | |
5 | Turn steering to left up to end stop and hold in this position. | ||
6 | Read off angle on scale of turn plate of left wheel of 1st front axle and measure distances (a, b) between front axle spring or drag link and tires on both front wheels of 1st front axle. | Steering angle of inner wheel | |
Distance, drag link to tire | |||
Distance, front spring to tire | |||
If the specified angle is not reached or if one of the distances (a, b) between the front axle spring or drag link and the tire is too small. | |||
| |||
Release counternut (2) of stop screw (1) on left steering knuckle of 1st front axle, and adjust steering stop by screwing in or unscrewing the stop screw (1) taking distances (a, b) between front axle spring or drag link and tire into consideration. Then lock stop bolt (1) using jam nut (2). | |||

7 | Turn steering to right up to end stop and hold in this position. | ||
8 | Read off angle on scale of turn plate of right wheel of 1st front axle and measure distances (a, b) between front axle spring or drag link and tires on both front wheels of 1st front axle. | Steering angle of inner wheel | |
Distance, drag link to tire | |||
Distance, front spring to tire | |||
If the specified angle is not reached or if one of the distances (a, b) between the front axle spring or drag link and the tire is too small. | |||
| |||
Release counternut (2) of stop screw (1) on right steering knuckle of 1st front axle, and adjust steering stop by screwing in or unscrewing the stop screw (1) taking distances (a, b) between front axle spring or drag link and tire into consideration. Then lock stop bolt (1) using jam nut (2). | |||

13 | Move front wheels to straight-ahead position. | ||
14 | Check for clearance of the tie rod relative to front-axle housing. | To do so, turn the steering completely to left and to right once and, while doing this, check whether the tie rod collides with the front axle housing. | |
If the tie rod collides with the front-axle housing, | |||
| |||
release jam nuts (2) on both sides. Reduce steering angle on both sides by unscrewing the stop screws (1) far enough until the tie rod no longer collides with the front axle housing. Then lock stop screws (1) with jam nuts (2). | |||
