BMW E46 M3 S54 3.2L Steering
Power steering coolers remove heat from power steering fluid to prevent damage to the pump and rack. Damaged coolers should always be replaced, and vehicles subjected to severe duty, or that operate in hot climates, should be upgraded to a larger cooler.
The steering knuckle unites several critical systems that suspend the chassis; support the drive axles and wheel hubs; mount the brakes; and allow the front wheels to turn when steering. Collision-damaged knuckles can adversely affect any and all of these functions, and make it impossible to properly adjust steering geometry.
Power steering pumps generate the hydraulic pressure needed by the steering assist system. Keep your pump working better and longer with quality drive belts, pulleys, fluids, and filters. If your pump is worn or damaged, install a new or remanufactured replacement from one of our trusted suppliers.
Power steering reservoirs store fluid for the pump and rack, and may contain a filter or strainer to keep the fluid clean. Reservoirs may crack and leak from heat and vibration, and filter replacement requires a fresh reservoir, in some applications. Why not include one in your next fluid service?
Tie rods and tie rod ends transfer steering inputs to the front wheels. Anchored at both ends by ball-and-socket tie rod pivots or bushings, these vital linkages take a constant beating from steering movement and road shocks transmitted by the wheels. Replace worn tie rods and ends to keep your steering taut, responsive, and safe.
