This 2006 Subaru Forester was bought to our Asian import auto repair shop in Ann Arbor with an oil leak and noisy power steering.
Diagnosis
An underhood inspection by our Subaru specialist technician found the power steering fluid level was low and the power steering pump was noisy due to air being drawn into the pump. The vehicle was lifted on the hoist for an under-vehicle inspection to find the power steering fluid leak. The high-pressure line from the pump to the steering rack unit and the return line were leaking.

Repair
The technician gained access to the power steering lines, replaced them with a new power steering hose and line replacement, and performed a power steering system fluid flush. The power steering system was filled with new fluid and operated to verify all leaks were repaired. Once the air was cleared from the steering system the power steering pump noise was gone.
The technician performed our quality assurance check and test-drove the vehicle to verify correct vehicle operation.
Tips
Power steering systems do not lose oil unless there is a fluid leak. If the power steering fluid level decreases the vehicle should be inspected for a leak. If the fluid level becomes too low the pump will suck air into the system which will cause pump noise and can affect the steering and vehicle control. If the fluid level gets low enough it can damage the pump.
Periodic power steering fluid flush and replacement will extend the life of the power steering rack, pump, and hoses.
Price
The price for Subaru power steering leak repair depends on the year, model, and work required. We are happy to perform a power steering fluid leak inspection and provide a detailed estimate.
Common Subaru Power Steering Leaks
- Common Power Steering fluid leaks on mid-2000s Foresters include worn high‑pressure or return hoses at the pump, hardened O‑rings on the pump inlet, and seepage from the pump shaft or body seals.
- When leaks appear near the Forester power steering pump and reservoir, we recommend replacing the high‑pressure line, return line, and the small O‑ring at the pump to eliminate all sources of fluid leakage. All these parts deteriorate with age, so they should be replaced at the same time.
- If the power steering hoses and seals are original, we recommend replacing hoses, clamps, and the pump together if there is visible wetness at multiple joints or the pump housing.
How can power steering leaks be found?
The technician can clean the area, add UV dye, and inspect with a black light. That way, they are not just guessing and replacing parts without seeing the actual leak point under load.
