Product Details
This Whiteline Rear Control Arm Upper Front Bushing fits the 2009-2013 BMW 328i xDrive 3 Series. Application note: Fits OEM Arm 33-32-2-406-289. The part number is W63403. It is listed for the E90/E91/E92/E93 chassis. Position: rear. Included: 4 shell bushings and 4 tubes.
Bushings work out of sight, but they decide how well a suspension holds its geometry. A soft or tired control arm bushing allows play that shows up as vague steering, a wandering feel under braking, or a clunk over bumps. Fitting a firmer one takes that slack out. The polyurethane used here deflects much less than the original rubber under the same load.
Installation is rated moderate, with about 3 hours of work listed. Get the car aligned once it is back on the ground. To go with it on the 328i xDrive 3 Series, see Adjustable Front Sway Bar Link, Rear Subframe Mount Bushing, and Front and Rear Essential Vehicle Kit.
