CONDITION POSSIBLE CAUSES CORRECTION
EXCESSIVE STEERING
WHEEL KICKBACK OR
TOO MUCH STEERING
WHEEL FREE PLAY.1. Air in the fluid of the power
steering system.1. Bleed air from system following the the
power steering pump initial operation
service procedure.*
2. Power steering gear loose on
cradle/crossmember.2. Inspect power steering gear mounting
bolts. Replace as necessary. Tighten to the
specified torque.
3. Steering column coupling or
intermediate shaft worn, broken or
loose.3. Replace steering column coupling or
intermediate shaft.
4. Free play in steering column. 4. Check all components of the steering
column and repair or replace as required.
5. Worn lower control arm ball joints. 5. Replace lower control arm ball joints as
required.
6. Loose steering knuckle-to-ball joint
stud pinch bolt.6. Inspect pinch bolt, replace as necessary,
and tighten to specified torque.
7. Front wheel bearing loose or
worn.7. Replace hub and bearing as necessary.
8. Loose outer tie rod end. 8. Replace outer tie rod end that has
excessive free play.
9. Loose inner tie rod. 9. Replace power steering gear.
10. Defective steering gear rotary
valve.10. Replace power steering gear.
* NOTE: Steering shudder can be expected in new
vehicles and vehicles with recent steering system
repairs. Shudder should dissipate after the vehicle
has been driven several weeks.
** NOTE: To evaluate this condition, it may be nec-
essary to disconnect the coupling at the base of the
steering column. Turn the steering wheel and feel or
listen for internal rubbing in steering column. To
avoid damaging the column clockspring, note the
following. Before disconnecting coupling, place
tires in the straight-ahead position and center steer-
ing wheel. Once disconnected, DO NOT rotatesteering wheel more than one revolution in either
direction and place steering wheel in original loca-
tion before reconnecting coupling. If this position is
lost, the steering column clockspring must be
recentered following the procedure found within the
procedure for steering column installation in the
steering column section.
*** NOTE: Increased low speed or stationary steer-
ing effort can be expected if the steering fluid is at
a high temperature. High fluid temperature usually
results from high engine rpm due to trailer towing,
ascending grades, or racing the engine for pro-
longed periods of time.
POWER STEERING FLUID
CONDITION POSSIBLE CAUSES CORRECTION
LOW FLUID LEVEL WITH
VISIBLE LEAK.1. Loose power steering hose
fittings.1. Tighten the fitting to its specified torque.
2. Damaged or missing fitting seal,
gasket, or O-ring.2. Replace as necessary.
3. Power steering component
leaking.3. Repair or replace the leaking component
as required.

FLUID COOLER
DESCRIPTION
Trailer Tow equipped vehicles are supplied with a
cooler for the power steering system fluid. The power
steering fluid cooler is located on the front suspen-
sion cradle crossmember reinforcement (Fig. 18).
OPERATION
The purpose of the power steering fluid cooler is to
keep the temperature of the power steering system
fluid from rising to a level that would affect the per-
formance of the power steering system.
The cooler used on this vehicle is referred to as a
fluid-to-air type cooler. This means that the air flow
across the tubes (and fines surrounding them) of the
cooler is used to extract the heat from the cooler
which it has absorbed from the power steering fluid
flowing through it. The cooler is placed in the power
steering fluid return line, between the steering gear
and the power steering fluid reservoir.
REMOVAL
(1) Using a siphon pump, remove as much fluid as
possible from the power steering fluid reservoir.
(2) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)(3) Remove the hose clamps at the cooler and
remove the hoses from the cooler inlet and outlet
tubes.
(4) Remove the 2 bolts attaching the power steer-
ing cooler cradle crossmember reinforcement (Fig.
19). Remove the cooler.
INSTALLATION
(1) Install the power steering fluid cooler on the
cradle crossmember reinforcement (Fig. 19). Install
the mounting bolts and tighten to 11 N´m (100 in.
lbs.).
(2) Install power steering fluid hoses on the cooler.
Be sure hose clamps are installed on hose past
the upset bead on the power steering cooler
tubes.
(3) Lower the vehicle to a point where front tires
are just off the ground.
(4) Perform Power Steering Pump Initial Opera-
tion procedure. (Refer to 19 - STEERING/PUMP -
STANDARD PROCEDURE)
