• Loose-feeling steering response related to stabilizer bar wear
• Uneven suspension noise during turns or over bumps

Installation Notes and Tips

Confirm the sway bar diameter before ordering, since this bushing is specified for 34mm applications and a 1.338-inch inside diameter. Verify front-to-frame placement and match the vehicle’s year, make, and model exactly to the listed fitment before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Delphi subjects steering and suspension components to temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure, to evaluate durability and corrosion resistance. The brand’s OE background and dimensional/material analysis support consistent replacement fit for TD5678W across the listed Buick, Oldsmobile, Pontiac, and Cadillac applications.
