Hearing a whine when you turn the wheel of your older Subaru? Your power steering pump might be calling it quits. This is a brand new, direct replacement power steering pump made for 1997, 1998, and 1999 Subaru Impreza and Legacy models with the 1.8L, 2.2L, or 2.5L H4 (flat-four) engine. Important: This pump does NOT include the reservoir or the pulley – you'll reuse your old ones. The outlet thread size is M14 x 1.5. It matches several OEM part numbers like 34411-AC100 and 34411-AC150. It's an unbranded unit, but it comes with a 1-year warranty, which is great. The fitment is spot-on, making it a straightforward swap for DIYers or shops. If your steering feels heavy or the pump is leaking, this affordable replacement will get your Subaru's steering feeling smooth and quiet again.
