Fitted to the 2005-2007 Volkswagen Jetta 2.5: the Whiteline Rear Upper Inner Control Arm Bushing. The part number is W63549. Position: rear. The listing names the 2.5 trim. The chassis code on the listing is 1K. You receive 2 bushings and 2 tubes.
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.
Installation is rated moderate, with about 3 hours of work listed. Plan on a wheel alignment afterward. To go with it on the Jetta, see Adjustable Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Front and Rear Sway Bar Kit.
