Detailed Description

Delphi TA2142 is a steering idler arm engineered for vehicles that rely on a center-link steering layout, including Chevrolet G10, G20, G30 and GMC G1500, G2500, and G3500 models. Delphi applies OE-focused dimensional and material analysis to help maintain correct geometry between the aftermarket part and the original steering system. The part is tested for temperature extremes and salt-spray exposure to support durability in demanding road conditions. This part cross-references MOOG Chassis Products K6248T and Mevotech Supreme MK6248T for the same application.

What It Helps Fix

• Excessive steering play from a worn idler arm
• Loose or wandering steering feel
• Uneven steering linkage movement
• Clunking or front-end noise related to steering wear
• Grease service issues on a non-greaseable or damaged component

Installation Notes and Tips

Verify steering linkage condition before installation and inspect related components such as the center link, pitman arm, and tie rod ends. Confirm the stud-style attachment and overall length match the original part before service. After installation, grease the fitting as part of routine chassis maintenance.

Quality Assurance

Delphi uses OE-based testing and dimensional checks for aftermarket steering parts, including exposure to temperatures below -40 degrees C and above 120 degrees C, plus 720 hours of salt spray testing. That validation supports fit consistency and corrosion resistance for long-term steering service.
