Product Details

This Dorman stabilizer bar bushing kit, part number 540-665, is built for front sway bar service on select full-size Ford platform vehicles. It is used where the stabilizer bar passes through the chassis mount, helping restore proper bar location and suspension feel on applications including the 1992-2002 Ford Crown Victoria, 1992-2002 Mercury Grand Marquis, and 1991-2011 Lincoln Town Car, depending on stabilizer bar diameter. This part cross-references MOOG Chassis Products K200167 for the same application.

Common Issues It Can Help Address

• Front suspension clunking or rattling from worn stabilizer bar bushings
• Excessive sway bar movement at the chassis mount
• Loose or degraded rubber bushings on the front stabilizer bar
• Reduced steering response caused by bushing wear
• Noise from bar-to-bracket contact

Installation Notes and Tips

Verify stabilizer bar diameter before ordering, since listed applications include 27.80 mm, 28 mm, and 28.50 mm bar notes. Confirm front position fitment and inspect the stabilizer bar brackets and mounting surfaces for wear before installation. Because mounting hardware is not included, reuse or replace related fasteners as needed during service.
