Help keep steering effort light and responsive with the TERREPOWER (formerly BBB Industries) N990-0462 Power Steering Pump, a direct-fit replacement for the 1995-1999 BMW M3 and 1998-2001 BMW Z3. This new pump supplies the hydraulic pressure the steering system uses to help turn the wheels, helping reduce the effort needed at the wheel during parking and low-speed turns.
The power steering pump is driven by the engine and sends pressurized fluid to the steering system to provide power assist. Signs this part may need replacing include a whining or groaning noise when turning, steering that feels heavy or inconsistent, and fluid leaking from the pump. Low fluid, a slipping drive belt or worn steering components can cause similar symptoms, so diagnose the cause before replacing the pump. If a failed pump is the cause, the N990-0462 replaces it on the listed applications.
