Subaru reports that some 2000-02 2.5L Legacy sedans and wagons and Outback models may emit a groan from the steering pump and/or a vibration through the steering wheel when turning at low speeds.
Issues with the high-pressure power steering hose are a likely cause.
If the noise or vibration is slight, try removing the high-pressure hose clamps and bolts at the frame to see if that reduces or eliminates the complaints. If it does, leave the clamps off and release the vehicle to the customer.
If the symptoms persist, replace the high-pressure hose with an updated design, Part No. 34610AE09B, leaving the retaining clamps off. If the noise or vibration remains after swapping in the new hose, Subaru said to replace the power steering pump, as well.
