Product Details
Whiteline Rear Upper Outer Control Arm Bushing is made for the 2015-2018 Audi A3 Quattro. Placement: rear. Chassis code: 8V. Whiteline part number: W63579. In the box: 2 shell bushings and 2 tubes. The listing names the Quattro trim.
A control arm bushing is the pivot where the arm joins the chassis or the wheel carrier. Factory rubber is chosen for quiet and comfort, so it squashes under braking, acceleration, and cornering and lets the arm move more than it should. A firmer replacement keeps the arm where it belongs, which steadies the alignment and gives the car a more consistent feel. The polyurethane used here deflects much less than the original rubber under the same load.
Expect a moderate job of about 3 hours. Plan on a wheel alignment afterward. Other Whiteline parts we list for the Audi A3: Adjustable Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Front and Rear Sway Bar Kit.
Features
- Material: Made from polyurethane.
- Bonded design: Bonding adds durability in high-load use.
- Self-lubricating: Grease reservoirs inside the bushing feed lubrication as it moves.
- Install guide: An install guide comes in the box.
- Bushing compound: A synthetic elastomer compound resists oil, grease, ozone, and weathering.
- Corrosion protection: Plated finish keeps rust off the hardware.
