What Does A Idler Arm Do

What is an idler arm? The idler arm assembly provides pivoting support for the steering linkage. Generally, an idler arm is attached between the opposite side of the center link from the pitman arm and the vehicle’s frame to hold the center link at the proper height so it can accurately relay the pitman arm’s movement.

How important is an idler arm?

Idler arms are particularly important for two reasons. First, as mentioned, the idler arm supports the right end of the track rod. Without it, the track rod would not hold the right wheel in place or turn it effectively, if at all. Second, the idler arm maintains proper toe angle.

Can a bad idler arm cause vibration?

Generally, worn steering parts such as idler arms, pitman arms and center links result in shimmy. Wheels that aren’t properly balanced can cause shimmy or shake. Imbalance usually causes the symptoms at a certain speed, above or below which there is no problem.

Can a worn idler arm cause play?

Over time the bearings in the arm’s bushings become worn, causing slack in the connection. Generally the only symptom of a bad idler arm is for the steering system to develop “play,” causing the vehicle to not respond to minor movements of the steering wheel.

What is the difference between idler arm and pitman arm?

The pitman arm is attached to the gearbox; it turns the center link as the driver steers the vehicle. The idler arm provides for swivel movement and resists up and down movement. This resistance is vital in maintaining a vehicle’s toe setting. When steering linkage gets loose, a vehicle will begin to shimmy.

Do you need an alignment after replacing an idler arm?

It depends. Of course the safest bet is to have a proper 4 wheel alignment done whenever a steering or suspension component is replaced, sometimes you can get away without having to do one and it’s a case by case basis.
