A control arm bushing is the pivot where the arm joins the chassis or the wheel carrier. Factory rubber is chosen for quiet and comfort, so it squashes under braking, acceleration, and cornering and lets the arm move more than it should. A firmer replacement keeps the arm where it belongs, which steadies the alignment and gives the car a more consistent feel. The polyurethane used here deflects much less than the original rubber under the same load.

Whiteline rates the install as moderate and lists about 2 hours. Get the car aligned once it is back on the ground. Working on the same car? We also list Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Front Sway Bar Link Assembly for the 440i Gran Coupe 4 Series.
