1999-2004 GMC Sierra 2500 Idler Arm Bracket Assembly

This part replaces:

  • OE # 19149615
  • OE # 12471378

  • New

This bracket (pivot) assy is what one side of the idler arm attaches to. The other end of the idler arm connects to the center or drag link on the passenger side of your steering linkage. Typically it supports the right hand side of your steering linkage by bolting to the bracket and pivoting the same as the pitman arm. Over time the bracket assembly can wear causing a sloppy steering feel.

Specifications:

  • Mounts on RH (Passenger Side) Front Frame
  • Idler arm bolts to it
  • Replaces dealer part numbers: 12471378, 19149615
  • Commonly referred to as the Idler Arm Housing
  • Direct replacement
  • Built to strict quality control standards

Remember whenever you are replacing any front end or steering components you should have your vehicle professionally aligned as soon as possible. This will ensure proper tracking and even tire wear.
