Help keep your steering linkage supported and responsive with the Delphi Idler Arm TA2129, backed by fatigue testing and precision-machined ball studs. It fits many vehicles, among them the 1978-1985 Chevrolet Impala, 1978-1983 Chevrolet Malibu and 1995-2005 Chevrolet Blazer, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
An idler arm supports one end of the steering center link and pivots as the wheels turn, helping hold the linkage in alignment. Delphi's OE safety technology is fitted to millions of vehicles worldwide, and the company applies that OE expertise to its aftermarket steering line. Extensive dimensional and material analysis helps ensure close compatibility between the OE and aftermarket part.
- Extreme-condition testing: Delphi tests its steering parts at temperatures below -40°C and above 120°C and exposes them to 720 hours of salt spray.
- Fatigue tested: Delphi idler arms are fatigue tested to help avoid failure.
- Precision ball studs: the ball studs are machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection: applied to each part to prevent corrosion and improve appearance.
Delphi includes the necessary accessories for the job. Signs an idler arm may need replacing include excess steering play, wandering on the road, uneven tire wear, or clunking when turning. If a worn idler arm is the cause, the TA2129 replaces it. Have the vehicle's alignment checked after any steering linkage work.
