A steering idler arm supports one end of the steering center link and pivots with it as you turn the wheel, which helps hold the linkage in position. Delphi applies the OE safety expertise behind millions of vehicles worldwide to its aftermarket steering line. It tests these parts at temperatures below -40°C and above 120°C and through 720 hours of salt-spray exposure. Dimensional and material analysis targets close compatibility with the OE part.
- Fatigue tested: Delphi fatigue tests its idler arms to help avoid failure.
- Precision ball studs: The ball studs are machined to micron tolerances for durability and smooth joint operation.
- Corrosion protection: Anti-corrosion protection is applied to each part to help prevent corrosion and improve its appearance.
- Ready for the job: Delphi includes the accessories needed for the installation.
An idler arm may need replacing if you notice excess play in the steering wheel, wandering or vague steering, clunking from the linkage when turning, or uneven tire wear. Tie rod ends and the center link can cause similar symptoms, so inspect the whole linkage first. An alignment check is recommended after installation.
