This page covers the Whiteline Rear Differential Mount Bushing for the 2017-2020 BMW 440i xDrive 4 Series. The kit contains 5 bushings, 3 tubes, 3 washers, an install guide, and grease. Chassis code: F32/F33. Placement: rear. Order it as part number KDT919.
Holding the differential still is about predictability. Rubber that is too soft lets it twist and move as load comes on and off, so the car squats and lurches a little more than it needs to. A firmer mount keeps it where it should be. Polyurethane resists deflection far better than the soft rubber it replaces.
Installation is rated difficult, with about 4 hours of work listed. Get the car aligned once it is back on the ground. Other Whiteline parts we list for the 440i xDrive 4 Series: Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Rear Lower Trailing Arm Bushing.
