Detailed Description

This Dorman sway bar bushing kit is designed for suspension service where the stabilizer bar bushing has worn, cracked, or lost its original shape. The bushing uses a steel bracket and a measured inside diameter of 17.31, with an outside diameter of 36.45 and assembled length of 1.55 in. It is listed for front-to-frame and rear-to-frame positions across select vehicles, including 1997-2001 Lexus ES300 front to frame, 1997-2004 Toyota Avalon front to frame, 2000-2005 Mitsubishi Eclipse rear to frame, and 1964-1973 Ford Mustang front to frame. This part cross-references MOOG Chassis Products K90393 for the same application.

What It Helps Address

• Clunking or rattling from a worn stabilizer bar bushing
• Excessive sway bar movement at the frame mount
• Loose-feeling front or rear suspension response
• Noise caused by deteriorated rubber bushing material
• Fitment issues on vehicles requiring an 18 mm or 17.46 mm diameter bar

Installation Notes and Tips

Verify stabilizer bar diameter before installation, since listed applications include both 18 mm and 17.46 mm bars. Confirm the mounting position on the vehicle, as this part is used in front-to-frame and rear-to-frame locations depending on application. Inspect the sway bar, frame bracket area, and surrounding hardware for wear before installing the new bushing kit. For best results, compare the removed part to the new Dorman 540-545 kit before assembly.

Quality Assurance

Dorman states that this suspension stabilizer bar bushing kit is precision-engineered and rigorously tested to provide reliable replacement for the original equipment on specific vehicles.
