A customer with a 2000-’02 Legacy sedan, wagon or Outback with a 2.5L engine may complain of an abnormal noise (groan) coming from the power steering pump and/or slight vibration in the steering wheel when turning at very low speeds.

The new style hose assembly was used in production starting in April 2002 with the following VINs: Legacy Sedan, 2*215560; Legacy Wagon, 2*310501; and Outback, 2*660215.

Repair Procedure:
1. Remove the bolt (A) and clamps (B) that secure the high-pressure power steering hose (see diagram).

2. Confirm that the abnormal noise and/or vibration has been reduced. If so, leave the clamps off; no further action is required.

3. If the abnormal noise and/or vibration have not been reduced, replace the high-pressure power steering hose with the updated hose, P/N 34610AE09B, and leave the clamps off.

4. If, after replacing the hose, the abnormal noise and/or vibration is still evident, replace the power steering pump.
