Power-assisted rack and pinion steering (ZHL)
Complaint:
Steering stiff or forces varying when steering into or out of curve (parking) (ZHL)
1.
In vehicles equipped with power-assisted rack and pinion steering and Servotronic, check the
converter/Servotronic using the DIS diagnosis program.
2.
Check the drivebelt for residues of coolant and oil and replace if necessary.
Important!
Always replace the drivebelt if it is soiled with hydraulic fluid.
(See Repair Instructions 11 28 010).
3.
Idle speed/idle speed fluctuating to below nominal value; engine speed not high enough for providing power
assistance. Adjust the engine speed.
(For nominal value, see Technical Data 13 00).
4.
Check the tyre pressure and adjust if necessary.
Is the rim/tyre size and the combination of rim and tyre approved?
5.
Check the fluid level in the reservoir. A definite loss of oil indicates there may be a leak or leaks in the steering
system. Check the steering system for leaks and repair, fill and bleed the system if necessary.
(See Repair Instructions 32 13 006).
6.
Check whether the steering column moves easily and repair if necessary:
-
Raise the vehicle.
-
With the engine off, turn the steering from lock to lock.
7.
Check whether the following components are damaged, stiff, corroded, worn, have play, are worn out: ball joints,
McPherson strut mounts, steering shaft bearings, universal joints of the steering shaft, track rod joints, flexible
wheel suspension joints, control arm bearings, tension rod bearings/rubber bushings, anti-roll bar bearings,
pendulum supports, ball joints on the rack, rubber covers and gaiters. If necessary, replace components.
