Have someone turn the steering wheel from left to
right. Check for movement between the ball stud end
at both the pitman arm and the steering arm. Also
check if the ball stud nut is loose.
If the ball stud end is loose, replace the drag link. If
the ball stud nut is loose, replace the nut and cotter
key. See
Group 46
of the vehicle Workshop Manual
for drag link removal and installation instructions.
See
Group 00
in this manual for torque specifica-
tions.
Inspect the boot of the drag link at both the pitman
arm and the steering arm end for cracks, splits, or
other damage. Replace the boot as needed.
Grasp the drag link near the pitman arm end, then
push and pull laterally to check for axial movement in
the ball stud end. If it is loose, replace the drag link.
If there is 1/8-inch (3-mm) movement or more, do not
drive the vehicle until the drag link is replaced.
