DESCRIPTION AND OPERATION

STEERING LINKAGE DESCRIPTION AND OPERATION

The steering linkage consists of the following components:

A pitman arm

An idler arm

A relay rod

2 adjustable 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 with the ball studs. The tie rods transfer the
steering force to the wheels. Use the tie rods in toe adjustments. The tie rods are adjustable. The
pitman arm support the relay rod. The idler arm pivots on a support attached to the frame rail and
the ball stud attaches to the relay rod.

The 2 tie rod are threaded into the tube and secured with jam nuts. Right and left hand threads are
used in order to permit the adjustment of toe.
