What It Helps Address

• Excess steering play caused by a worn idler arm
• Loose or wandering steering feel on Chevrolet C10, C20, and C30 trucks
• Front-end steering linkage movement on GMC C1500, C2500, and C3500 models
• Uneven steering response in Chevrolet and GMC R-series and P-series applications
• Service issues related to a dry or non-greaseable steering support component

Installation Notes and Tips

Verify the vehicle’s steering linkage configuration before installation and compare the original part dimensions to the 5.39 in. length. Because this idler arm is greaseable, service the fitting after installation and during routine chassis maintenance to help maintain steering performance.

Quality Assurance

Delphi applies OE-focused engineering to its steering portfolio and validates parts through temperature and corrosion testing, including exposure below -40 degrees C, above 120 degrees C, and extended salt-spray testing. Delphi TL480 is built to support consistent replacement fitment on Chevrolet and GMC steering systems.
