Dorman 522-871 Front Left Lower Rearward Control Arm

Dorman 522-871 is a suspension control arm and ball joint assembly for specific BMW applications, including front left lower rearward positions. It is built as a direct replacement for the original equipment design to help restore smooth ride quality, directional stability, and predictable handling on BMW 535i GT, 550i GT, 740i, 740Li, 750i, 750Li, 760Li, and ActiveHybrid 7 models.

Key Features

• Direct replacement suspension control arm and ball joint assembly
• Pre-greased for ready-to-install service
• Ball joint installed with a press-in mounting design
• Threaded ball joint stud with 14 mm thread diameter
• Aluminum control arm construction with rubber bushings

Detailed Description

This Dorman suspension control arm assembly is engineered for the front left lower rearward position and is compatible with select BMW chassis applications. The aluminum control arm uses rubber bushings and an installed ball joint to match the original suspension layout, helping maintain proper wheel control and suspension response. Dorman part number 522-871 is evaluated to support consistent ride behavior and stable steering feel in everyday driving.

This part cross-references Beck/Arnley 102-7678 and Delphi TC2833 for the same application. It is a practical OE-style replacement for BMW 535i GT, 550i GT, and 7 Series models where the original control arm and ball joint assembly has worn or lost precision.

What It Helps Address

• Front-end looseness or reduced steering precision
• Clunking or knocking from a worn lower control arm
• Uneven tire wear caused by suspension wear
• Directional instability during braking or lane changes
• Ball joint or bushing wear in the front suspension

Installation Notes and Tips

Verify the front left lower rearward position before installation. This assembly uses a press-in ball joint design and includes mounting hardware, so proper suspension service tools and torque procedures are important. Because the control arm is not adjustable, final alignment should be performed after installation to confirm correct suspension geometry.

Quality Assurance

Dorman evaluates this control arm and ball joint assembly through an industry-focused validation process to help deliver consistent ride quality, directional stability, and predictable suspension dynamics. The part is built as a direct replacement for the original equipment on the listed BMW applications.
