Here is the Whiteline Rear Control Arm Lower Inner Bushing for the 2010-2013 Lexus IS250 C. Placement: rear. Chassis code: XE20. In the box: 2 shell bushings and 2 tubes. Part number W63581. Trim named on the listing: C.
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. Polyurethane resists deflection far better than the soft rubber it replaces.
Whiteline rates the install as difficult and lists about 3 hours. Plan on a wheel alignment afterward. To go with it on the IS250, see Front Control Arm Lower Inner Rear Bushing, Rear Differential Bushing – Front Mount Kit, and Heavy Duty Blade Adjustable 18mm Rear Sway Bar.
