This steering idler arm is used in the steering linkage to help maintain alignment between the center link and the rest of the front steering system. On vehicles such as the Dodge Charger and Chrysler New Yorker, correct idler arm condition is important for stable steering response and predictable wheel movement.
What It Helps Address
- Excessive steering play or looseness in the linkage
- Uneven steering response caused by worn pivot points
- Front-end wandering related to steering support wear
- Noisy or unstable steering linkage operation
- Restoring proper center-link support on classic Chrysler and Dodge platforms
Installation Notes
Verify vehicle application by year, make, and model before installation. Inspect related steering components such as the center link, tie rod ends, and mounting points for wear before replacing the idler arm. The greaseable design allows routine lubrication after installation to support service life.
Quality Assurance
Delphi applies OE engineering practices to its aftermarket steering parts and validates components through dimensional and material analysis. Testing includes exposure to extreme temperatures below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure to evaluate durability in demanding conditions.
