(See Repair Instructions 32 13 006).
4.
Check whether the pump mount is fitted correctly and adjust if necessary.
5.
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.
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.
The lines have not been run correctly. A line has been incorrectly clamped or is kinked; lines are making contact
with each other or with other vehicle parts. Adjust the run of the line(s).
8.
The system is leaking, sucking in air, making sucking noises and the fluid is foaming in the reservoir. Locate the
leak and repair, fill and bleed the system.
(See Repair Instructions 32 13 006).
9.
Loud grinding and clacking noises can be clearly heard when turning the steering wheel to full lock: the pressure
relief valve in the power steering pump is faulty. Replace the pump.
10. If points 1 - 9 are OK: the fault may be in the power steering pump. Replace the pump.
Complaint:
Chattering when driving over bumps in road with steering turned (ZHL)
1.
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.
2.
Check whether all relevant threaded chassis and suspension joints and steering components are fitted securely
and tighten if necessary.
(For tightening torques, see Technical Data.)
3.
The lines have not been run correctly. A line has been incorrectly clamped or is kinked; lines are making contact
with each other or with other vehicle parts. Adjust the run of the line(s).
Power-assisted recirculating-ball steering (KMH)
Complaint:
Steering stiff or forces varying when steering into or out of curve (KMH)
1.
In vehicles equipped with power-assisted recirculating-ball steering and Servotronic, check the
converter/Servotronic using the DIS diagnosis program.
E38 only: On converters manufactured up to production date week 40/95 (see rating plate), there is a possibility
of intermediate cover of the converter corroding. Replace the converter.
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.
