Product Details
This Whiteline Rear Differential Mount Bushing fits the 2017-2020 BMW 440i xDrive Gran Coupe 4 Series. Placement: rear. In the box: 5 bushings, 3 tubes, 3 washers, an install guide, and grease. 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. The polyurethane used here deflects much less than the original rubber under the same load.
Expect a difficult job of about 4 hours. An alignment is required after installation. To go with it on the 440i xDrive Gran Coupe 4 Series, see Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Front Sway Bar Link Assembly.
Features
- Install guide: Step-by-step installation instructions come with it.
- Grease: Molybdenum disulfide grease is included to help the parts last.
- Bushing compound: The bushing material stands up to oil, grease, ozone, and weather.
- Finish: A powder coated finish resists corrosion and wear.
- Bushing material: Polyurethane bushings flex far less than rubber ones.
- Self-lubricating: Built-in grease reservoirs provide continual lubrication and reduce friction.
