Idler Arm

Idler Arm – Maintenance for Off-Road Riding

An idler arm connects from the frame to the center link and supports the center link as it pivots side to side. Another way to locate the idler arm is to look at the opposite end of the center link where the pitman arm connects. Together, the idler arm and pitman arm rotate in unison while keeping the center link parallel to the ground. Idler arms often have replaceable bushings or bearings that can be replaced to eliminate play in the arm. If the idler arm is greasable, regularly greasing it will increase the life of the part. A worn idler arm can cause “toe in” to change and free play in the steering.
