Detailed Description

Delphi TD4789W is engineered as a rear stabilizer bar bushing kit for vehicles that use a 17 mm rear sway bar. Delphi applies OE-focused dimensional and material analysis to help match aftermarket fitment to the original part, and the rubber construction supports consistent bushing performance in everyday driving conditions. This part cross-references MOOG Chassis Products K201317 and Mevotech Supreme MK201317 for the same application.

What It Helps Address

• Rear sway bar movement caused by worn bushings
• Clunking or rattling from the rear suspension area
• Excessive play in the stabilizer bar mounting point
• Reduced rear-end stability during cornering
• Uneven bushing wear from age, heat, and road exposure

Installation Notes and Tips

Confirm rear sway bar diameter and vehicle option content before installation, especially on Park Avenue, DeVille, and Seville applications with suspension package notes. Inspect the stabilizer bar and surrounding brackets for wear or corrosion before installing the new bushings. Because mounting hardware is not included, reuse or replace related fasteners as needed during service.

Quality Assurance

Delphi subjects its OE-style steering and suspension parts to extreme temperature testing below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure for corrosion resistance evaluation. The brand’s OE background and dimensional analysis support consistent aftermarket replacement fitment for the listed Buick and Cadillac applications.
