Whiteline Rear Diff Bushings – Subaru Models 2002-2003 WRX / 1998-2008 Forester / 1995-1999 Legacy

Whiteline Rear Diff Bushings – Subaru Models 2002-2003 WRX / 1998-2008 Forester

Firm Up the Rear Differential on Classic Subaru AWD Models
The rear differential mount bushings on the 2002-2003 Subaru WRX and 1998-2008 Forester allow the differential to move under hard acceleration and cornering. This movement creates drivetrain vagueness and inconsistent rear axle behavior. Whiteline’s polyurethane replacement bushings reduce differential movement and improve power delivery precision on these classic AWD platforms.

DETAILS

• Polyurethane rear differential mount bushings
• Reduces differential movement under acceleration and cornering loads
• Improves drivetrain precision and rear axle stability
• Fitment: 2002-2003 Subaru WRX and 1998-2008 Forester (GD/SF/SG chassis)
• Direct press-fit replacement

Rear Differential Mounting on Classic Subarus
The 2002-2003 GD WRX and SF/SG Forester are classic platforms that have accumulated significant mileage. The rear differential mount bushings on these cars are almost universally softened or worn on high-mileage examples. Fresh polyurethane bushings restore the differential stability that makes these AWD cars feel precise and connected.

Forester Coverage
The SF (1998-2002) and SG (2003-2008) Forester have compatible rear differential mount geometry. One bushing spec covers a decade of Forester production across two generations.

Part of a Classic Subaru Drivetrain Refresh
The rear differential mount bushings work alongside transmission mount inserts, pitch stop mounts, and control arm bushing replacements to produce a comprehensively refreshed classic Subaru drivetrain.

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

Foundational drivetrain mount maintenance for classic Subaru AWD models. Simple to install, immediately felt improvement. 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.
