Steering Linkage Description and Operation
WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
The steering linkage consists of the following components:
- A pitman arm
- An idler arm
- A relay rod
- Inner and outer tie rods
When you turn the steering wheel the steering gear rotates the pitman arm which forces the relay rod to one side. The tie rods connect to the relay rod at the ball studs. The tie rods transfer the steering force to the wheels. The tie rods are used when making toe adjustments. The idler arm pivots on a support attached to the frame rail and the ball stud attaches to the relay rod.
