Front Right Upper Control Arm, Lemforder - E39 540i/M5

The Thrust Rod (upper control arm) on your E39 535, 540 or M5 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 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 thrust arm manufactured by Lemforder - an original supplier to BMW for this part, as well as many other XXXX. 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.
