DIAGNOSIS AND TESTING
Steering System
Inspection and Verification
CAUTION: Do not hold the steering wheel (3600) at the stops for an extended amount of
time. Damage to the power steering pump (3A674) will result. NOTE: Make the following preliminary checks before repairing the steering system:

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

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

GENERAL PROCEDURES
System Flushing —
CII Power Steering Pump
WARNING: Do not mix oil types. Any mixture or any unapproved oil can lead to seal
deterioration and leaks. A leak can ultimately cause loss of fluid, which can result in a loss of
power steering assist.
1. Remove the fuel pump fuse from the battery junction box.
2. Disconnect the power steering return hose. Plug the reservoir.
3. Attach an extension hose between the power steering return hose and an empty container.
4. Raise the front wheels off the floor. For additional information, refer to Section 100 - 02 .
5. Check the fluid level. If necessary, fill the reservoir to the correct level. zUse Motorcraft MERCON® Multi-Purpose ATF XT -2-QDX or MERCON® equivalent.
6. CAUTION: Do not crank the engine for more than 15 seconds at a time. Allow the
starter to cool for 1 minute before cranking again. Premature starter failure can occur.
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.
Turn the steering wheel from stop- to-stop while cranking the engine until the fluid exiting the
power steering return hose is clear of all contamination and foreign material.
zAdd Motorcraft MERCON® Multi-Purpose ATF XT -2-QDX or MERCON® equivalent as
needed.
7. Lower the vehicle.
8. Disconnect the extension hose from the power steering return hose. Remove the plug. Attach the power steering return hose to the reservoir.

GENERAL PROCEDURES
Purging —CII Power Steering Pump
CAUTION: If the air is not purged from the power steering system correctly, premature
power steering pump failure can result. This condition can occur on pre- delivery vehicles with
evidence of aerated fluid or on vehicles that have had steering component repairs.
1. NOTE: A whine heard from the power steering pump may be caused by air in the system. The
power steering purge procedure must be performed prior to any component repair for which
power steering noise complaints are accompanied by evidence of aerated fluid.
Remove the reservoir cap. Check the fluid level. If necessary, fill the reservoir to the correct
level.
zUse Motorcraft MERCON® Multi-Purpose ATF XT -2-QDX or MERCON® equivalent.
2. Tightly insert the Vacuum Pump stopper into the reservoir.
3. Start the vehicle.
4. Using the special tool, apply maximum vacuum and maintain it for a minimum of three minutes with the engine speed set at idle. SECTION 211-
