Detailed Description

This Dorman suspension control arm and ball joint assembly is built as an OE-style replacement for BMW X5 and BMW X6 front suspension service. The aluminum arm, rubber bushings, and pre-installed ball joint are selected to match the original suspension layout and help maintain proper alignment behavior. Dorman 524-809 is a practical choice when replacing a worn front left upper control arm on 2007-2018 BMW X5 or 2008-2019 BMW X6 models with the listed negative 30 degree camber setting.

This part cross-references MOOG Chassis Products RK620976 and Delphi TC3891 for the same application.

What It Helps Address

• Clunking or knocking from the front suspension
• Excessive play in the upper control arm or ball joint
• Uneven tire wear related to worn suspension geometry
• Steering wander or reduced directional stability
• Alignment issues tied to a worn front left upper arm

Installation Notes and Tips

• Install in the front left upper position only on the listed BMW X5 and BMW X6 applications.
• Verify the negative 30 degree camber setting before installation.
• Inspect adjacent suspension components, bushings, and alignment settings during service.
• Professional alignment is recommended after replacement to confirm suspension geometry.
• Confirm fitment by year, make, model, and position before ordering.
