The steering linkage consists
of the following components:
The turning motion of the steering wheel is transmitted
through the steering gear (1) and the pitman arm  to the relay rod.
The relay rod (2) incorporates a ball joint at each end. The relay rod
is connected to the forward steering arm (7) on the left side. The tie rod
  tube (4) extends the length of the axle, which controls the right    wheel.
 The tie rod  tube connects    the right and  left tie rod ends  (5)  to the
 tie rod arms (6).
The overall condition of the steering linkage affects the steering performance.
Inspect the steering linkage components for the following conditions:
The above conditions may cause improper and possibly dangerous steering
