Front Left Upper Control Arm, Lemforder - E9X 325xi/328xi/330xi/335xi

The upper control arm on your E9X 325xi/328xi/330xi/335xi incorporates a large, soft bushing that is designed to remove all vibration normally transmitted through the steering system while still doing a decent job at controlling loads from the tire. The control arm is also known as the traction strut, thrust arm, or radius rod.

The soft, rubber bushing naturally wears prematurely, causing sloppy steering, poor tire wear, and jolting or instability during braking. The ball joint in the arm can also become worn and cause bad handling and wear, so we always recommend checking it along with the bushing and lower control arm (track rod) when diagnosing issues.

This is an OEM E9X thrust arm manufactured by Lemforder - the original supplier to BMW for this part, as well as many other suspension components. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.

Priced individually per control arm. For LEFT / DRIVER side. The outer ball joint is sold separately, see link below.
