This is the Genuine BMW front left wishbone / lower control arm kit for the F10 535xi/550xi, F06 640xi/650xi GranCoupe, and F12/F13 640xi/650xi (AWD xDrive) models. This is the factory BMW overhaul kit that includes the arm and hardware.
The wishbone is the rear-most control arm on the F10/F06/F12/F13 front suspension. The arm includes two rubber bushings but not the outer ball joint (see below for link). The center bushing is the mount for the front shock absorber. Both bushings do a great job of isolating bumps and rough roads, until the rubber is worn.
Worn F10/F06/F12/F13 bushings will affect the ride, handling, and steering of the car and can also cause clunking noises and vibrations. A new bushing is only available with the complete wishbone (not sold separately). To restore steering precision and taught handling, replace the complete wishbone at the first sign of wear.
This is a Genuine BMW control arm kit with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
