Product Details
Fitted to the 2017-2021 Volkswagen Golf/GTI: the Whiteline Rear Upper Outer Control Arm Bushing. In the box: 2 shell bushings and 2 tubes. Order it as part number W63579. The chassis code on the listing is AU. Position: rear.
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 moderate and lists about 3 hours. Plan on a wheel alignment afterward. Other Whiteline parts we list for the Golf/GTI: Adjustable Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Front Control Arm Lower Inner Front Bushing.
Features

- Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
- Corrosion protection: Metal parts are plated to resist rust over the long term.
- Install guide: Step-by-step installation instructions come with it.
- Self-lubricating: Internal grease reservoirs keep the bushing lubricated as it works.
