Product Details
This Whiteline Rear Control Arm Lower Rear Inner and Outer Bushing fits the 2006 BMW 330xi 3 Series. The part number is W63400. This part is for the rear of the vehicle. Whiteline's note for this fit: Fits front and rear positions of OEM arm 33-32-6-763-477. In the box: 4 shell bushings and 4 tubes. It is listed for the E90 chassis.
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. Polyurethane resists deflection far better than the soft rubber it replaces.
Installation is rated moderate, with about 3 hours of work listed. Plan on a wheel alignment afterward. To go with it on the 330xi 3 Series, see Rear Subframe Mount Bushing, Rear Differential Mount Bushing, and Front Lower Radius Arm Bushing.
