Whiteline Rear Upper Control Arm Inner Bushing – 2000-2009 Subaru Legacy

Whiteline Rear Upper Control Arm Inner Bushing – 2000-2009 Subaru Legacy

Restore Rear Camber Geometry on Your BH or BP Legacy
The rear upper control arm inner bushing on the 2000-2009 Subaru Legacy is the inner chassis mount of the rear upper arm — a position that affects rear camber geometry under cornering loads. When worn, angular play at this mount allows camber to vary dynamically rather than staying at the aligned value. Whiteline’s polyurethane replacement restores geometric consistency.

DETAILS

• Polyurethane compound for rear upper control arm inner position
• Fits 2000-2009 Subaru Legacy (BH/BE and BP/BL chassis)
• Reduces dynamic rear camber variation under load
• Improves rear axle precision and handling consistency
• Limited Lifetime Warranty

Legacy Rear Suspension Precision
The Subaru Legacy’s multi-link rear suspension is capable of excellent handling when the bushings are in good condition. High-mileage examples — particularly the GT and XT variants used for performance driving — accumulate wear at the upper arm inner position that shows up as rear end imprecision and inconsistent cornering grip.

Inner vs. Outer Bushing
The inner bushing (this product) and the outer bushing (WHLW63397) work together to define how the upper arm moves. Replacing just the inner without inspecting the outer is incomplete. Whiteline covers both positions for the Legacy rear suspension.

BL/BP Legacy GT Focus
The turbocharged Legacy GT and Outback XT are the most performance-oriented variants of these generations. Under spirited driving and track use, the rear bushing wear accelerates. This bushing is particularly valuable for GT owners who want to restore the handling precision the car is capable of.

Why Choose Whiteline

Whiteline has been engineering suspension components from their facility in Australia since 1979. Every product in their catalog is developed with a clear goal: measurable improvement in handling, stability, and tyre contact. Whiteline’s polyurethane bushings, sway bars, control arms, and alignment correction kits are engineered using finite element analysis and validated on track before they reach the market. Their components are direct-fit, bolt-on solutions designed for enthusiasts who want real performance gains without fabrication or custom work.

The RallySport Take

A targeted maintenance item for Legacy rear suspension precision. Often overlooked but directly impactful on rear handling consistency. 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.
