1. Inflate tires to specified pressure.

2. Improper front wheel alignment.

2. Check and adjust wheel alignment as
necessary.

3. Lack of lubrication causing binding
in front lower control arm ball joints.

lubricated for life type, then inspect ball joint
for wear. Replace lower control arm as
necessary. If ball joint is a lubricated for life
ball joint, replace lower control arm.

4. Steering column coupling joints
misaligned.

4. Realign steering column coupling joints.

5. Steering wheel rubbing.**

5. Adjust steering column shrouds to
eliminate rubbing condition.

POSSIBLE CAUSES

CORRECTION

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 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 rotate
steering 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.

AERATED FLUID.*

1. Low fluid level.

1. Fill power steering fluid reservoir to
proper level.

2. Air leak at supply hose, power
steering fluid reservoir or pump.

2. Inspect for proper sealing. Repair as
necessary.

3. Cracked power steering pump
housing.

3. Replace the power steering pump.

RESERVOIR FLUID
OVERFLOW AND FLUID
THAT IS MILKY IN COLOR

1. Water contamination of power
steering fluid.

1. Drain the power steering fluid from the
system. Flush the system with fresh clean
power steering fluid, drain, then refill to the
proper level.

* NOTE: Extremely cold temperatures may cause
power steering fluid aeration. Aeration should sub-
side as fluid warms.
