Detailed Description

Dorman 526-687 is engineered as a replacement suspension control arm assembly for the front left lower location on BMW i3 and BMW i3s models. It combines the control arm and ball joint into one service part to restore suspension function where wear, looseness, or damage has affected steering response and ride quality. This part cross-references Mevotech Supreme CMS101608 for the same application.

The assembly uses an aluminum control arm with a machined ball joint mounting type and threaded stud design. It includes bushings, a dust boot, and a pre-greased ball joint to support consistent operation after installation. The painted finish and standard replacement construction make it a practical choice for replacing the original front suspension component on the BMW i3 and BMW i3s.

What It Helps Fix

• Front-end clunking or looseness from a worn control arm assembly
• Uneven steering feel caused by ball joint wear
• Directional instability during braking or lane changes
• Suspension noise from deteriorated bushings
• Loss of proper front left lower suspension geometry

Installation Notes and Tips

Verify vehicle fitment by year, model, and front left lower position before installation. The Dorman 526-687 includes mounting hardware, a castle nut, and a locking nut, and the ball joint is pre-greased. Because this is a suspension component, final tightening should be performed with the vehicle at normal ride height when required by service procedure. After installation, a wheel alignment is recommended to confirm suspension geometry and steering tracking.
