Delphi Rear Stabilizer Bar Bushing Kit TD4457W

Delphi TD4457W is a rear suspension stabilizer bar bushing kit built as a standard replacement for select Subaru applications. It uses rubber construction and OE-focused dimensional analysis to support proper fitment on the rear sway bar, including Subaru Legacy, Outback, Baja, and Impreza models listed below.

Key Features

• Rubber bushing construction with black finish
• Standard replacement grade for rear suspension service
• Inside diameter: 14.8 mm / 0.582 in.
• Width: 25.0 mm / 1.69 in.
• Height: 37.0 mm
• Rear position application
• OE-based material and dimensional analysis for fit consistency

Detailed Description

Delphi TD4457W is a rear stabilizer bar bushing kit engineered for suspension service on select Subaru Legacy, Subaru Outback, Subaru Baja, and Subaru Impreza vehicles. Delphi applies OE-level testing and material analysis to aftermarket steering and suspension components, with validation that includes extreme temperature exposure and salt-spray durability testing. The result is a rear sway bar bushing replacement that follows the original part’s size and material profile for the listed applications. This part cross-references Dorman OE Solutions 928-509 for the same application.

What It Helps Address

• Rear sway bar bushing wear that can create looseness in the suspension
• Clunking or rattling from the rear stabilizer bar area
• Excessive play at the rear anti-roll bar mounting points
• Degraded rubber bushings from age, heat, or road exposure
• Restoring stable rear suspension response on Subaru Legacy, Outback, Baja, and Impreza models
