GENERAL DESCRIPTION

Outer track rod assembly
Pitman arm
The steering linkage consists of a pitman arm,
relay lever, center track rod and two adjustable
outer track rods.
When the steering wheel is turned, the gear rotates
the pitman arm which forces the center track rod to
one side. The outer track rods, connected to the
center track rod by ball studs, transfer the steering
force to the wheels. The outer track rods are
adjustable and are used for toe-in adjustments.
The center track rod is supported by the pitman
arm and relay lever. The relaylever pivots on a
support attached to the frame.
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. Refer to Front End
Alignment (Sec. 3A).
