Steering Linkage

The steering linkage is composed of a pitman arm, connecting rod, two idler arms, relay rod and two adjustable tie rods.

When the steering wheel is turned, the steering gear rotates the pitman arm, which forces the connecting rod to one side moving the relay rod. The tie rods, which are connected to the relay rod by ball studs, transfer the steering force to the wheels. The tie rods are adjustable and are used for toe-in adjustments. The relay rod is supported by the idler arms. The idler arms pivot on a support attached to the frame rail.

The overall condition of the steering linkage affects steering performance. If parts are bent, damaged, worn or poorly lubricated, improper and possibly dangerous steering action will result.

Whenever any steering linkage components are repaired or replaced, check the steering geometry and front end alignment.
