Whiteline built the Rear Control Arm Lower Rear Inner Bushing for the 2004-2012 Volvo S40 (P1). Whiteline part number: W63321. You receive 2 shell bushings and 2 tubes. It goes on the rear of the vehicle.
Every time the wheel moves, the control 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. The polyurethane used here deflects much less than the original rubber under the same load.
Whiteline rates the install as moderate and lists about 2 hours. An alignment is required after installation. Working on the same car? We also list Adjustable Rear Sway Bar Link, Adjustable Rear Upper Control Arm Set, and Adjustable Front Sway Bar Link for the Volvo S40.
