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 2 hours of work listed. Plan on a wheel alignment afterward. 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 xDrive Gran Coupe 4 Series.
