Product Details
This Whiteline Rear Upper Inner Control Arm Bushing Kit fits the 2015-2020 Audi A3 (8V). Placement: rear. The kit contains 2 shell bushings, 2 tubes, 4 washers, an install guide, and grease. Whiteline part number: W63578.
Bushings work out of sight, but they decide how well a suspension holds its geometry. A soft or tired control arm bushing allows play that shows up as vague steering, a wandering feel under braking, or a clunk over bumps. Fitting a firmer one takes that slack out. The polyurethane used here deflects much less than the original rubber under the same load.
Installation is rated moderate, with about 3 hours of work listed. Get the car aligned once it is back on the ground. To go with it on the Audi A3, see Adjustable Rear Sway Bar Link, Adjustable Rear Upper Control Arm Set, and Adjustable Front Sway Bar Link.
Features
- Bushing compound: The bushing material stands up to oil, grease, ozone, and weather.
- Material: Polyurethane construction.
- Install guide: Written install instructions are included with the part.
- Grease: Molybdenum disulfide grease comes with it for a longer service life.
- Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
- Bushing material: Polyurethane is firmer than the factory rubber, so it deflects less under load.
