1999-2004 GMC Sierra 2500 Idler Arm

This part replaces:

  • OE # 15891516

  • New

This replacement Idler Arm is just what you need to ensure the safety and integrity of your vehicle's suspension and steering.

Specifications:

  • Bolts to RH (Passenger Side) Frame
  • Replaces dealer part numbers: 15891516
  • Attaches to relay rod or drag link
  • Direct replacement
  • Built to strict quality control standards
  • Is arm only, does not include mounting bracket
  • Does NOT fit models with Rack & Pinion Steering

Your idler arm connects to the center link on the passenger side of your steering linkage. Typically it supports the right hand side of your steering linkage by bolting to the frame and pivoting the same as the pitman arm. Over time the greasable ends and even the holes in the arm can wear causing loose connections and a sloppy steering feel.

Remember whenever you are replacing any front end or steering components you should have your vehicle professionally aligned as soon as possible.
