Power Steering Troubleshooting Chart
Review this troubleshooting chart any time a power steering system problem is present. This chart will help deter-
mine if the power steering pump or power steering gear is functioning properly.
CONDITIONPOSSIBLE CAUSES CORRECTION
Steering Wheel Is Loose · Steering wheel retaining bolt loose.
· Loose steering column to
instrument panel fasteners.· Check steering wheel retaining bolt
torque and tighten to specifications if
necessary.
· Check steering column to
instrument panel fastener torque and
tighten to specifications if necessary.
Steering Catches, Surges Or Sticks
In Certain Positions Or Is Difficult To
Turn · Low power steering fluid level.
· Tire(s) not properly inflated.
· Loose or slipping power steering/
accessory drive belt.
· Lack of lubrication in steering gear
outer tie rod end(s).· Check fluid level and fill to proper
level if necessary. Check for leaks.
Make sure all air is bled from
system.
· Check and inflate tires to the
specified pressure.
· Verify belt tension. Replace belt
auto-tensioner and belt if necessary.
· Check the outer tie rod ends.
Steering Wheel Does Not Return To
Center Position · Tire(s) not properly inflated.
· Improper front wheel alignment.· Check and inflate tires to the
specified pressure.
· Check and adjust wheel alignment
if necessary.
Excessive Steering Wheel Kickback
From Road Inputs · Air in power steering fluid.
· Power steering gear loose on
cradle/sub-frame.
· Steering column, coupling or
intermediate shaft worn or loose.
· Power steering pump flow is too
low.· Inspect for excessive air bubbles in
fluid (fluid will appear foamy and
lighter in color). Inspect hoses for
leaks and replace if necessary.
Bleed air from fluid.
· Inspect gear mounting bolts.
Replace if necessary and tighten to
specifications.
· Rotate steering wheel back-and-
forth while inspecting intermediate
shaft going into steering gear. Look
for excessive free-play. Retighten if
loose bolt is found. Replace steering
column, coupling or intermediate
shaft if necessary.
· Perform power steering flow and
pressure test. Look for low or erratic
flow or pressure. Replace power
steering pump if necessary.

NOTE :
Extremely cold temperatures may cause power steering fluid aeration. The air should work its way out of the system
as the fluid warms.
CONDITIONPOSSIBLE CAUSES CORRECTION
Low Fluid Level With Visible Leak · Loose power steering hose fittings
or connections.
· Damaged or missing O-ring at
power steering hose tube nuts.
· Power steering line or hose failure.
· Power steering component leaking
(reservoir, pump, gear).· Check torque on all tube nuts (at
gear and pump). Inspect clamps at
all rubber hose connections for
correct position, damage and
tension. Tighten tube nuts to
specifications as required.
Reposition or replace clamps at
hose connections. Clean joints and
reinspect for leaks.
· Remove tube nut and inspect
O-ring. If damaged or missing,
replace O-ring. Clean joints and
reinspect for leaks.
· Clean fluid from around suspect
areas. Run vehicle and inspect for
leaks. Look inside reservoir to see if
air is being ingested. Replace hoses
if necessary.
· Clean fluid from around suspect
areas. Run vehicle and inspect for
leaks. Look inside reservoir to see if
air is being ingested. Replace power
steering component if necessary.
Aerated Fluid · Low power steering fluid level.
· Air leak at power steering supply
hose, reservoir or pump.· Check fluid level and fill to proper
level if necessary. Check for leaks.
Make sure all air is bled from
system.
· Inspect components. Place a hand
vacuum pump with reservoir and
verify that system can sustain
vacuum. System should not lose
more than 1 psi in 2 minutes (make
sure vacuum pump is sealed well to
the reservoir). Replace steering
component if necessary.

1. If the power steering fluid level is low, inspect the entire power steering system for potential leaks.
CAUTION:
DO NOT operate the vehicle with foamy steering fluid for an extended period. This may cause
pump damage.
2. Perform the following to inspect the power steering fluid reservoir level:•Park the vehicle on a level surface.
• Start the engine.
• Turn the steering wheel several times to heat the power steering fluid to 50°- 60°C.
• With the engine running, turn the steering wheel left and right to the wheel stops and repeat this several
times.
• Check the power steering fluid reservoir to see whether there is foam or milky fluid present. Check the
fluid level difference between engine off (2)
and engine running (1). If the fluid level varia-
tion exceeds 5 mm, air is in the system and
the air should be bled from the power steering
system.

NOTE :
This test should be performed during a road test.
•Make smooth turns and sharp turns. Check the driving senseto ensure there is no difference between the left
and right turns in terms of steering force and the steering wheel returning to center.
• When the vehicle speed is between 20 to 30 km/h, turn the steering wheel 90° for 1 or 2 seconds and release
the steering wheel. If the steering wheel returns
over 70°, the steering wheel return function can be
considered good.
NOTE :
When rapidly turning the steering wheel, there will be a sense of “heavy”, however, this does not indicate a problem
with the steering system. This is due to insufficient steering fluid supplied to the steering fluid pump during idle
speed.
Steering Column Shroud
Removal & Installation
WARNING!
Before servicing the steering column, the airbag system must be disarmed. Failure to do so may result in acci-
dental deployment of the airbag and possible personal injury (See Airbag System Disarming Procedure in Sec-
tion 14 Restraints).
NOTE :
To help maintain alignment of the spiral cable connector during reassembly, apply a small piece of tape to the spiral
cable and the steering column to keep them in alignment. 1. Disconnect the negative battery cable.
2. Remove the driver airbag (See Driver Airbag Removal & Installation in Section 14 Restraints).
3. Remove the steering wheel lock nut (1). (Tighten: Steering wheel lock nut to 25 - 30 N·m)

Installation Notes:
• Check the steering shaft and universal joint for damage or wear. Check the clearance of universal joint and
replace if necessary.
• Check the steering column seal cover. The distance to the groove button should be less than 1.00 mm, replace
if necessary.
• Verify the airbag system is operating properly after the repair is complete.
• When installing the spiral cable, slowly wind the spiral cable to the end of its travel and then unwind the spiral
cable two and a half turns.
