9. If an obvious cause for an observed or reported malfunction is found, correct the cause (if
possible) before proceeding to the next step.
10. If the fault is not visually evident, determine the symptom and proceed to the following symptom chart.
Steering System Symptom Definitions
Drift/Pull
Pull is a tugging sensation, felt by the hands on the steering wheel, that must be overcome to keep the
vehicle going straight.
Drift describes what a vehicle with this condition does with hands off the steering wheel.
zA vehicle-related drift/pull, on a flat road, will cause a consistent deviation from the straight-
ahead path and require constant steering input in the opposite direction to counteract the effect.
z Drift/pull may be induced by conditions external to the vehicle (i.e., wind, road camber).
Excessive Steering Wheel Play
Excessive steering wheel play is a condition in which there is too much steering wheel movement
before the wheels move. A small amount of steering wheel free play is considered normal.
Feedback
Feedback is a roughness felt in the steering wheel when the vehicle is driven over rough pavement.
Hard Steering or Lack of Assist
Hard steering or lack of assist is experienced when the steering wheel effort exceeds specifications.
Hard steering can remain constant through the full turn or occur near the end of a turn. It is important
to know the difference between hard steering/lack of assist and binding.
Hard steering or lack of assist can result from either hydraulic or mechanical conditions. It is extremely
important to know if this concern occurs during driving, during very heavy or static parking maneuvers.
Nibble
Sometimes confused with shimmy, nibble is a condition resulting from tire interaction with various road
surfaces and observed by the driver as small rotational oscillations of the steering wheel. Poor Returnability/Sticky Steering Visual Inspection Chart

Component Tests
Steering Linkage
1. NOTE: Excessive vertical motion of the studs relative to the sockets may indicate excessive
wear.
With the parking brake applied, perform the following:
zHave an assistant rotate the steering wheel back and forth 360 degrees and watch for
relative motion of the studs in the tie- rod end ball sockets.
z Watch for loose steering gear mounting.
2. Another method is to raise the front wheels (1007) off the ground, grasp the wheel at the front and rear and watch for excessive play or binding in the joints while trying to steer the wheels.
3. Install new steering components as necessary. For additional information, refer to the appropriate Group 2 steering section.
Turning Effort Test
NOTE: Make sure that the front wheels are properly aligned and the tire pressure is correct before
checking the effort.
1. Park the vehicle on dry concrete and set the parking brake.
2. Insert a thermometer into the power steering pump reservoir.
3. CAUTION: Do not hold the steering wheel against the stops for more than three to
five seconds at a time. Damage to the power steering pump will occur.
Idle the engine for two to three minutes. Turn the steering wheel from stop- to-stop several times
to warm the fluid to 50- 60°C (122-140°F).
4. With the engine running, attach special tool 211- 034 (T74P-3504-Y) to the rim of the steering
wheel.
5. Measure the pull required to turn the steering wheel one complete revolution in each direction. Refer to Steering Wheel Turning Effort under General Specifications in this section.
Pump Flow and Pressure Test WARNING: Do not touch the flowmeter during the test procedure, or severe burns and
serious injury may occur.
1. CAUTION: Make sure that the connection point will not interfere with any of the
engine accessory drive components or drive belts.
Install special tool 211- F001 (014-00207) at the high pressure port of the power steering pump.
Make sure the power steering analyzer gate valve is fully open. Klj . 8 ba

z
On some vehicles, the power steering pump high pressure port is inaccessible and the
special tool should then be installed either at the steering gear or at a point in the high
pressure line between the power steering pump and the steering gear.
2. Place a dial thermometer in the power steering pump reservoir.
3. Check the power steering fluid level. If necessary, add power steering fluid. zUse Motorcraft MERCON® Multi-Purpose ATF XT -2-QDX or MERCON® equivalent.
4. Install a digital tachometer.
5. CAUTION: Do not hold the steering wheel against the stops for more than three to
five seconds at a time. Damage to the power steering pump will occur.
Start the engine. Place the transmission in neutral. Set the parking brake. Raise the power
steering fluid temperature to 74- 80°C (165-175°F) by rotating the steering wheel fully to the left
and right several times.
6. Set the engine speed to 1500 rpm. Record the flow rate and pressure readings. zIf the flow rate is below the flow rate specification, a new power steering pump may need
to be installed. Continue with the test procedure.
z If the pressure reading is above the maximum pressure specification, then check power
steering hoses for kinks and restrictions.
7. Partially close the gate valve to obtain 750 psi. Set the engine speed at idle. Record the flow rate.
zIf the flow is less than the specified flow rate, then install a new power steering pump. For
additional information, refer to Section 211 - 02 .
8. CAUTION: Do not allow the gate valve to remain closed for more than 5 seconds.
Completely close and partially open the gate valve 3 times. Record the pressure relief valve
actuation pressure reading. zIf the pressure does not meet the relief pressure specification, install a new power
steering pump. For additional information, refer to Section 211 - 02 .
9. Set engine speed to 1500 rpm. Record the flow rate. zIf the flow rate varies more than 3.785 liters/minute (1 gallon/minute) from the initial flow
rate reading, install a new power steering pump. For additional information, refer to
Section 211 - 02 .
10. CAUTION: Do not hold the steering wheel against the stops for more than three to
five seconds at a time. Damage to the power steering pump will occur.
Set the engine speed at idle. Turn (or have an assistant turn) the steering wheel to the left and
right stops. Record flow rate and pressure readings at the stops.
zThe pressure reading at both stops should be nearly the same as the maximum pump
relief pressure.
z The flow rate should drop below 1.9 liters/minute (0.5 gallons/minute).
z If the pressure does not reach the maximum pump relief pressure or the flow rate does
not drop below the specified value, excessive internal leakage is occurring. Install a new
steering gear as necessary. For additional information, refer to Section 211 - 02 . Klj . 9 ba

11. Turn (or have an assistant turn) the steering wheel slightly in both directions and release quickly
while watching the pressure gauge.
zThe pressure reading should move from the normal back pressure reading and snap
back as the steering wheel is released.
z If the pressure returns slowly or sticks, the rotary valve in the steering gear is sticking or
the steering column is binding. Check the steering column and linkages before servicing
the steering gear.
Tie- Rod Articulation Torque
1. NOTE: This check may be done with the steering gear on or off the vehicle.
Disconnect the tie- rod end from the front wheel spindle. For additional information, refer to
Section 211 - 02 .
2. Move the front wheel spindle tie- rod back and forth three times.
3. Hook the special tool 211- 034 (T74P-3504-Y) over the tie-rod end or the threaded portion of the
front wheel spindle tie- rod and measure the force required to move the front wheel spindle tie-
rod. Refer to Tie- Rod Articulation Torque in General Specifications in this section.
4. If the force required to move the front wheel spindle tie- rod does not meet the specifications,
install a new front wheel spindle tie- rod. For additional information, refer to Section 211 - 02 .
Steering Gear Valve 1. With the vehicle in motion, place the transmission in NEUTRAL and turn the engine OFF. zIf the vehicle does not pull with the engine OFF, install a new steering gear. For
additional information, refer to Section 211 - 02 .
2. If the vehicle pulls with the engine OFF, cross- switch the front wheels.
3. If the vehicle pulls to the opposite side, cross- switch the front and rear wheels on the same side.
4. If the vehicle pull direction does not change, check the front suspension components, wheel alignment and frame alignment. For additional information, refer to Section 204 - 00 or frame
dimensions manual. Klj . 10 ba
