Looking for a rear differential bushing for your 2017-2021 BMW 230i xDrive 2 Series (F22/F23)? The Whiteline Rear Differential Mount Bushing is made for it. Placement: rear. In the box: 5 bushings, 3 tubes, 3 washers, an install guide, and grease. The part number is KDT919.
The differential is hung from the chassis on bushings that are soft for comfort. Under hard acceleration and braking they let it rock, so power reaches the wheels a moment late and the rear end can feel loose. A firmer bushing holds the differential more steadily, which sharpens throttle response. Polyurethane resists deflection far better than the soft rubber it replaces.
Whiteline rates the install as difficult and lists about 4 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 Rear Lower Trailing Arm Bushing for the 230i xDrive 2 Series.
