SUBJECT:
Model 209.372/472

Noises / Vibration at Steering Wheel with A/C switched on

If you receive customer reports in the above model vehicles of a groaning noise and vibration felt in the steering wheel at engine speeds between 800 - 2000 RPM (mostly heard around 1600 RPM) and with the A/C on, the cause may be the transfer of vibration from the A/C compressor through the high pressure power steering hose to the steering wheel. To remedy, install a rubber buffer at the high pressure power steering line to the steering gear bracket as described below.

Note:
Noise and vibration frequency might change at the steering wheel end stops and then reduces with the A/C off.

Note:
Refer to published WIS, DTB and other documents relating to this condition.

Procedure:

1. Remove lower engine compartment paneling. Refer to WIS document AR61.20-P-1105P.





2. Remove screws (Figure 1, 1 and 2) from the brackets securing the high pressure power steering line (power steering pump to the steering gear hose).





3. Gently move the line and install rubber buffer (Figure 2, 3) by screwing it into the power steering rack housing (hole after removing the screw 1 in Figure 1).

Note:
Do not over tighten the rubber buffer as the rubber part might tear.





4. Position the high pressure power steering line bracket onto the installed rubber buffer as depicted in Figure 3 (arrow), and secure it with nut (Figure 2, 4). Tighten to 10 Nm

5. Reattach the screw (Figure 1, 2) with the bracket at the other end of the high pressure power steering line.

Note:
Ensure that the high pressure power steering line does not come in contact with other parts of the vehicle.

6. Reinstall lower engine compartment paneling as per step 1.

Note:
Always refer to EPC for latest and additional parts information.
