Product Details
This Whiteline Rear Lower Trailing Arm Bushing fits the 2017-2020 BMW 440i Gran Coupe 4 Series. Placement: rear. Part number W63591. The kit contains 4 shell bushings and 4 tubes. Application note: Fits OEM Arm 33-32-6-792-525.
Every time the wheel moves, the trailing arm swings on its bushings. When they are soft or worn, the arm shifts under load, the alignment changes as the car moves, and steering and braking feel less precise. A stiffer bushing cuts that unwanted movement while still letting the arm pivot freely.
Installation is rated moderate, with about 2 hours of work listed. An alignment is required after installation. 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 Gran Coupe 4 Series.
Features
- Corrosion protection: Plated finish keeps rust off the hardware.
- Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
- Grease: Moly grease is supplied to prolong the life of the parts.
- Install guide: An install guide comes in the box.
- Bonded design: The bushing is bonded for strength where loads are highest.
- Bushing compound: The elastomer formulation is chosen to shrug off oil, grease, ozone, and the elements.
