Product Details
This Whiteline Front Upper and Lower Control Arm Bushing Kit fits the 1979-1986 GMC C1500 Suburban. In the box: 8 bushings, 8 tubes, and grease. Whiteline part number: W56421. Position: front. This listing is for RWD models.
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.
Expect a difficult job of about 3 hours. Plan on a wheel alignment afterward. Other Whiteline parts we list for the C1500 Suburban: 26.9mm Front Sway Bar Mount Bushing Kit.
