Whiteline Rear Differential Mount Bushing for 2017-2019 BMW 340i GT xDrive 3 Series (F34)

Fitted to the 2017-2019 BMW 340i GT xDrive 3 Series (F34): the Whiteline Rear Differential Mount Bushing. It goes on the rear of the vehicle. You receive 5 bushings, 3 tubes, 3 washers, an install guide, and grease. Trim named on the listing: xDrive 3 Series. Order it as part number 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. The polyurethane used here deflects much less than the original rubber under the same load.

Whiteline rates the install as difficult and lists about 4 hours. An alignment is required after installation. To go with it on the 340i GT, see Adjustable Sway Bar Vehicle Link Kit, Rear Subframe Mount Bushing, and Rear Lower Trailing Arm Bushing.
