Whiteline Rear Control Arm Upper Rear Outer Bushing – 2006-2011 BMW 3 Series Models

Restore Rear Geometry on Your E9x BMW
The rear upper control arm rear outer bushing on the 2006-2011 BMW 3 Series (E9x) is the wheel-side mount of the rear upper arm. When this bushing wears, the arm shifts at its outer pivot under cornering loads, allowing rear camber variation that degrades the E9x’s rear axle precision. Whiteline’s polyurethane replacement restores the geometric consistency these platforms require.

E9x Upper Arm Outer Bushing Wear
The outer bushing of the rear upper arm is the wheel-side pivot — the point closest to the wheel hub. Wear here allows the most direct camber variation under load. High-mileage and track-used E9x examples show wear at this position.

Part of Complete E9x Rear Package
Whiteline covers all E9x rear arm positions. The upper rear outer bushing works alongside the lower front inner (W63401) and lower rear inner/outer (W63400) positions for a complete rear suspension rebuild on the E9x platform.

E9x M3 Application
On the E9x M3 used for track days, rear bushing quality is foundational. Fresh polyurethane bushings throughout the rear suspension keep geometry consistent through the heat cycling and loads of track use.

The RallySport Take

Targeted outer bushing replacement for E9x BMW rear suspension precision. Budget an afternoon for the job — bushing replacement is not complicated but does require the correct press tools and clean installation technique. Apply grease to all polyurethane-to-metal interfaces and assemble at ride height for correct bushing set. The improvement in chassis feel is immediate and the polyurethane will outlast whatever rubber is in there now.
