E9x Rear Lower Arm Wear
The E9x 3 Series rear lower control arm has both inner and outer mount positions that wear with mileage and performance use. The rear positions (both inner and outer) take significant loads under braking — these are high-priority positions for bushing replacement on any E9x used for spirited driving.

Both Positions Together
The rear inner and rear outer bushings on this arm work together to define how the arm pivots under braking and cornering loads. Replacing one without the other is incomplete — the W63400 covers both positions in one purchase.

Part of E9x Rear Bushing Package
The rear lower arm positions work alongside the front inner bushing (W63401) for a complete rear lower arm rebuild on the E9x platform.
