Idler Arms

 

Idler Arms

Idler Arms create the proper steering linkage height by connecting one end of the linkage to the frame. It also creates a pivot point for the steering linkage.

What is an Idler Arm and what does it do

How Does it Work?

  • Holds the center link at the proper height.
  • Opposite side from the Pitman arm.

How is it Made?

  • An idler arm has either a tapered hole or a ball joint on the end connecting to the center link, and a mounting portion that is bolted to the frame or sub-frame.

Why Does it Fail?

  • Rough road conditions.
  • Driving wear.

What are the Symptoms of Failure?

  • Under car noise.
  • Erratic steering.
  • Drifting.
  • Front-end shimmy.

What are the Implications of Failure?

  • Arm becomes loose.
  • Damaged.
  • Sometimes only one idler arm may be failing, but it’s good practice and insurance to replace both.

How Difficult is the Install?
