Delphi TD4045W Suspension Stabilizer Bar Bushing Kit - Front

Delphi Front Stabilizer Bar Bushing Kit

Delphi TD4045W is a front suspension stabilizer bar bushing kit built as a standard replacement for select Chevrolet, Pontiac, and Oldsmobile applications. It is sized for a 21.5 mm bar diameter and uses a black bushing design to support front sway bar mounting and reduce unwanted movement at the bar-to-chassis connection.

Detailed Description

Delphi TD4045W is engineered for front stabilizer bar service where correct bushing size and material fit matter. Delphi applies OE-focused dimensional and material analysis to help match the original bar interface, and the part is tested across extreme temperature ranges and salt-spray exposure to verify durability in demanding road conditions. This part cross-references MOOG Chassis Products K6651 for the same application.

Use TD4045W when servicing front sway bar bushings on vehicles such as the Chevrolet Malibu, Pontiac Grand Am, and Oldsmobile Alero, especially where the application calls for a 21.5 mm bar diameter. The Delphi TD4045W part number is also a useful reference when confirming the correct front stabilizer bar bushing kit for these platforms.

What It Helps Address

• Front sway bar clunking caused by worn bushings
• Excess stabilizer bar movement at the chassis mount
• Loose or inconsistent front-end handling feel
• Noise from deteriorated suspension bushings
• Fitment issues when replacing a 21.5 mm front stabilizer bar bushing

Installation Notes

Confirm the front stabilizer bar diameter before installation, especially on 2003 Chevrolet Malibu, 2003 Oldsmobile Alero, and 2003 Pontiac Grand Am applications that require a 21.5 mm bar. Inspect the stabilizer bar surface and mounting area for wear or corrosion before fitting the new bushings. Because mounting hardware is not included, reuse or replace related fasteners as needed during service.

Quality Assurance

Delphi validates this suspension bushing through OE-oriented dimensional checks and material analysis, along with temperature and corrosion testing that reflects real-world service conditions. The TD4045W is a standard replacement part backed by Delphi’s OE engineering approach for front suspension service.
