Key Features

• Rubber bushing material with a black finish
• Inside diameter: 22.0 mm for 22mm rear sway bar applications
• Standard replacement, regular grade
• Rear position application
• Delphi OE-based dimensional and material analysis for aftermarket fitment
• Tested across extreme temperatures and salt spray exposure for durability validation

Detailed Product Overview

Delphi TD5447W is engineered for rear stabilizer bar service where the original bushing has worn, cracked, or lost its ability to hold the sway bar securely. This part number, TD5447W, is built around OE-style specifications and is intended for vehicles that use a 22mm diameter rear sway bar. It is a direct-fit style replacement for select Buick, Oldsmobile, Pontiac, and Cadillac rear suspension applications, including Buick LeSabre, Pontiac Bonneville, and Oldsmobile 88 models listed in the fitment data.

This part cross-references MOOG Chassis Products K201019 and also interchanges with 25558129 for the same application.

What This Part Helps Address

• Rear sway bar movement caused by worn bushings
• Clunking or rattling from the rear suspension area
• Excessive play at the stabilizer bar mounting point
• Reduced bar control from cracked or hardened rubber bushings
• Fitment issues when replacing an OE-style 22mm rear stabilizer bushing

Installation Notes and Tips

Confirm the rear sway bar diameter before installation; this bushing is specified for 22mm diameter applications. Verify the vehicle’s rear suspension configuration against the fitment list before ordering, especially on Buick LeSabre, Pontiac Bonneville, and Oldsmobile 88 models. Inspect the stabilizer bar and mounting surfaces for wear or corrosion during service so the new bushing seats correctly.

Quality Assurance

Delphi applies OE-focused testing and dimensional analysis to its aftermarket steering and suspension portfolio. This bushing is validated through temperature exposure below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray testing to evaluate material durability and corrosion resistance in demanding conditions.
