TrueDrive RB28150005 Front Lower Rearward Control Arm Right Side OEM Replacement

The TrueDrive RB28150005 is a front lower rearward control arm designed as a direct OEM replacement for the right (passenger) side suspension on BMW 7-Series and 5-Series vehicles. This control arm directly replaces BMW OEM part numbers 31126775964 and 31126798108, ensuring a precise factory-spec fit without modification.

The front lower control arm is a critical suspension component that links the vehicle's chassis to the wheel hub assembly. A worn or failed control arm can cause vibration and shaking transmitted through the steering wheel, suspension noise, improper steering alignment, and accelerated tire wear. Restoring this component returns the suspension system to proper geometry and ensures safe, predictable handling.

Key Features:

• Direct OEM replacement — no cutting, welding, or modification required
• Right (passenger) side front lower rearward position
• Replaces BMW OEM part numbers 31126775964 and 31126798108
• Engineered to restore factory suspension geometry and alignment
• Designed for optimized stiffness and corrosion resistance for long-term durability
• Restores proper steering response, ride comfort, and tire wear characteristics

This is the rearward lower control arm for the front right suspension — note that BMW front lower suspension uses two control arms per side (frontward and rearward). For best results, inspect related suspension components including bushings and ball joints at time of replacement.
