Differential Bushes with Fitting Position Rear Axle for SUBARU IMPREZA WRX STi GD Sedan

WRX STi GD Sedan IMPREZA Differential bushes are the polyurethane bush kits used to replace worn rubber bushes at the front and rear differential mounting positions. The differential mount bushes isolate the differential housing from the subframe or chassis, controlling movement under acceleration, braking and cornering loads while absorbing drivetrain vibration before it reaches the body. On independent rear suspension vehicles, the rear differential is mounted at two or more positions with separate front and rear bush locations, each playing a distinct role in controlling differential movement and NVH. On 4WD and all-wheel-drive platforms, front differential mount bushes perform the same function at the front axle.

As factory rubber differential mount bushes wear, they allow increased differential movement under load, introducing drivetrain vibration, clunking under acceleration and deceleration, and rear end instability that progressively worsens. Quality WRX STi GD Sedan IMPREZA polyurethane replacements restore correct differential location, reduce unwanted movement and significantly lower the NVH transmitted through the mount interface. A reliable repair and upgrade solution for workshops and experienced DIY users across a wide range of passenger, performance, 4WD and applications. Installation guides are available across most products. Most products are backed by a lifetime warranty.

Why Upgrade WRX STi GD Sedan IMPREZA Suspension?

Differential mount bushes carry continuous drivetrain load and are subject to heat, oil contamination and the cyclical torque reversals generated under acceleration and braking. Factory rubber bushes in these positions degrade progressively, softening and cracking in a way that allows the differential to move beyond its designed operating position under load. The result is increased drivetrain noise, vibration transmitted into the cabin under throttle input, and in more advanced cases, a clunking or thunking sensation as the differential shifts position under rapid load changes.

Replacing worn WRX STi GD Sedan IMPREZA differential mount bushes with correctly specified polyurethane alternatives restores correct differential location at each mounting position, significantly reducing movement-related NVH and improving the precision and refinement of drivetrain feel under all driving conditions. For performance and driving where increased power output places greater demand on differential mount compliance, quality polyurethane bushes deliver more consistent differential location and a more direct, responsive drivetrain character.

WRX STi GD Sedan IMPREZA Differential Bush Range

The WRX STi GD Sedan IMPREZA differential bush range includes:

• WRX STi GD Sedan IMPREZA Rear Differential Mount Front Bush Kits: Bush kits for the front mounting position of the rear differential, restoring differential location and reducing NVH at the front mount interface.
• WRX STi GD Sedan IMPREZA Rear Differential Mount Rear Bush Kits: Bush kits for the rear mounting position of the rear differential, restoring correct compliance and reducing movement at the rear mount interface.
• WRX STi GD Sedan IMPREZA Rear Differential Mount Combined Bush Kits: Kits covering both front and rear mount positions on applicable platforms in a single purchase.
• WRX STi GD Sedan IMPREZA Front Differential Mount Bush Kits: Bush kits for the front differential mounting positions on applicable 4WD and AWD platforms.
• WRX STi GD Sedan IMPREZA Differential Mount Location Rod Bush Kits: Bush kits for location rod mounting positions on applicable commercial van platforms.
• WRX STi GD Sedan IMPREZA Front Differential Drop Kits: Kits that relocate the front differential mounting position on applicable 4WD platforms fitted with a suspension lift.

Why Purchase WRX STi GD Sedan IMPREZA Differential Bushes?

Allowing worn differential mount bushes to remain in service results in ongoing drivetrain NVH, progressive differential movement under load and a reduction in the refinement and precision of drivetrain feel across all driving conditions. Renewing them with quality polyurethane alternatives restores correct differential location at each mount position, eliminates movement-related noise and vibration and returns a more direct, controlled drivetrain character from the moment of installation.

For workshops carrying out drivetrain servicing and suspension overhauls, differential bush renewal is a cost-effective step that addresses a common and frequently overlooked source of drivetrain NVH on high-mileage vehicles. For performance and modified WRX STi GD Sedan IMPREZA owners, polyurethane differential mount bushes deliver improved differential location and a more responsive drivetrain that reflects the level of precision demanded by the build.

Installation and Support

WRX STi GD Sedan IMPREZA Differential bush kits are designed for accurate installation at the front and rear differential mounting positions. Installation times range from approximately one to six hours depending on the application and number of positions being renewed. Installation guides are available across most products to support professional workshops and experienced DIY users. For additional technical assistance, a dedicated support team is available to help ensure correct product selection and fitment.

Repair and Upgrade

WRX STi GD Sedan IMPREZA Differential bushes are manufactured from high-strength polyurethane engineered to withstand the continuous drivetrain load, heat, oil exposure and cyclical torque inputs that differential mount positions are subject to in everyday and demanding use. Resistant to oil, heat and road contaminants, polyurethane differential mount bushes maintain their compliance characteristics for longer than factory rubber alternatives, delivering more consistent differential location and reduced NVH throughout their service life. Most products are backed by a lifetime warranty.

Who WRX STi GD Sedan IMPREZA Differential Bushes Are For

WRX STi GD Sedan IMPREZA Differential bushes are a practical solution for:

• Professional workshops carrying out drivetrain servicing and suspension overhauls requiring differential mount bush renewal across a range of passenger, performance, 4WD and commercial platforms.
• Experienced DIY users replacing worn differential mount bushes to eliminate drivetrain vibration, reduce NVH and restore correct differential location under load.
• Performance and modified vehicle owners requiring polyurethane differential mount bushes to improve differential location and deliver a more direct, responsive drivetrain character.
• Anyone experiencing drivetrain clunking, vibration under acceleration or deceleration, or rear end instability attributable to worn or deteriorated differential mount bushes.

The right differential bush kit restores correct differential location, reduces drivetrain NVH and delivers a more precise, refined and controlled drivetrain feel every time.
