Power steering fluid is an unfiltered fluid. Over time the additives in the fluid wear out and abrasive particulates accumulate in the fluid causing wear on moving parts. Periodic flushing will extend the life of the power steering pump as well as the Rack and Pinion unit. Our ASE-certified mechanics will determine if a vehicle needs this flush by inspecting the power steering fluid. If they see black gritty substances or smell a burning scent, a flush will be recommended.
