Replace a worn front suspension link in one step with the Dorman control arm 520-738, built for the front right lower rearward position and designed as a direct replacement for the original assembly on the 1997-2003 BMW 540i, 2000-2003 BMW M5 and 1999-2000 BMW 540iT. This Dorman suspension control arm and ball joint assembly arrives with its ball joint and bushings already in place.
- Trustworthy replacement: Directly replaces the original equipment arm on the listed applications.
- Complete repair: The ball joint and bushings come pre-installed, saving time and labor.
- Quality engineering: Put through an industry-leading testing and evaluation process intended to deliver a smooth, stable and safe ride, with directional stability and predictable dynamics.
- Durably designed: Additional coatings provide rust and corrosion resistance.
The Dorman lower control arm connects the wheel carrier to the vehicle's chassis, and its ball joint lets the wheel pivot as the suspension travels and the steering turns. Signs this part may need replacing include clunking or knocking over bumps, loose or wandering steering, uneven tire wear, or a damaged ball joint boot. If the original arm or its ball joint is the cause, this assembly replaces both at once. Consult the vehicle service information for the correct fasteners and torque specifications, and have the wheel alignment checked after installation. For engine-specific details, see the "Vehicles it fits" section.
