46–01 Drag Link Inspection
WARNING
All steering system components are critical for
safe operation of the vehicle. Failure to maintain
the steering system as specified may result in
loss of steering control, which could lead to per-
sonal injury and property damage.
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 00 for torque specifications.
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. See
Group 46 of the
Century Class Trucks Workshop
Manual
for drag link removal and installation instruc-
tions.
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.
See Group 46 of the
Century Class Trucks Work-
shop Manual
for replacement instructions. If there is
1/8-inch (3-mm) movement or more, do not drive the
vehicle until the drag link is replaced.
46–02 Power Steering Fluid
and Filter Change
WARNING
Fill only with approved clean fluid. Failure to use
the proper fluid could cause seal deterioration and
leaks. Fluid leaks could eventually cause loss of
power steering assist. This could lead to an acci-
dent resulting in personal injury or property dam-
age. Wear eye protection when changing the fluid
and filter.
1. Apply the parking brakes and chock the rear
tires.
2. Place a drain pan under the power steering res-
ervoir, and remove the steering gear-to-reservoir
return hose at the reservoir. Drain the power
steering fluid into the drain pan and dispose of
the fluid properly. Plug the return line fitting on
the reservoir.
3. Use the following procedure for Century Class
Conventionals. For Argosy COEs, go to the next
step.
3.1 Use one hand to apply downward pres-
sure to the power steering reservoir
cover. Remove the flanged nut and rub-
ber washer. See Fig. 1. Remove the
cover.
NOTE: Always replace the power steering
reservoir filter when changing the fluid.
