Power Steering Flush in Windsor, CA
Flush the complete power steering system.
Flush fluid every 30K miles.
Mineral fluids extra.
Any fluid that churns and is under high pressure will wear out in time and be contaminated. Replacing this fluid every 30K miles or so saves the power steering pump seal and the seal in the gear box. On some vehicle it saves the life of seal in the rack and pinion unit. By the way these are all the components that let you steer so easily. Yet no manufacturer ever recommends replacing this fluid.
