REMOVAL AND INSTALLATION
Spring
Removal
CAUTION: Suspension fasteners are critical parts because they affect performance of vital
components and systems and their failure can result in major service expense. A new part with
the same part number or an equivalent part must be installed, if installation is necessary. Do
not use a part of lesser quality or substitute design. Torque values must be used as specified
during reassembly to ensure proper retention of these parts.
1. Mark the front shock absorber (18124) relative to the protective sleeve with the vehicle in a static, level ground position (curb height).
2. Raise the vehicle on a hoist. For additional information, refer to Section 100 - 02 .
3. Remove the wheel and tire assembly. For additional information, refer to Section 204 - 04 .
4. Remove the cotter pin and nut. Discard the cotter pin.

necessary, the part must be of the same finish and property class. Torque values must be used
as specified during reassembly to make sure of correct retention of these parts.
1. Mark the rear shock absorber (18125) relative to the protective sleeve with the vehicle in a static, level ground position (curb height).
2. Remove the muffler assembly(ies). For additional information, refer to Section 309 - 00 .
3. Remove the rear spring (5560). For additional information, refer to Spring — Coil in this section.
4. Remove the lower suspension arm and bushing (5A649) from the body attachment. 1. Remove and discard the bolt and nut.
2. Remove the lower arm.
Installation 1. Install the lower suspension arm and bushing to the body attachment. 1. Position the lower arm. 2. Install a new bolt and a new nut. Do not tighten at this time. SECTION 204-

Repair the axle as necessary. Make sure the axle lubricant is at the correct level. Refer to
Specifications in this section.
Axle Vent
NOTE:
If a plugged vent cannot be cleared, install a new one.
A plugged vent will cause excessive seal lip wear due to internal pressure buildup. If a leak occurs,
check the vent. Make sure the vent hose is not kinked. Remove the hose from the vent nipple and
clear the hose of any foreign material. While the hose is removed, pass a length of mechanics wire in
and out of the vent to clean it. Connect the hose when done.
Flange Yoke Seal
Leaks at the axle drive pinion seal originate for the following reasons:
zSeal was not correctly installed.
z Poor quality seal journal surface.
Any damage to the seal bore (dings, dents, gouges, or other imperfections) will distort the seal casing
and allow leakage past the outer edge of the axle drive pinion seal.
The axle drive pinion seal can be torn, cut, or gouged if it is not installed carefully. The spring that
holds the axle drive pinion seal against the pinion flange may be knocked out and allow leakage past
the lip.
The rubber lips can occasionally become hard (like plastic) with cracks at the oil lip contact point. The
contact point on the pinion flange may blacken, indicating excessive heat. Marks, nicks, gouges, or
rough surface texture on the seal journal of the pinion flange will also cause leaks.
When a seal leak occurs, install a new seal and check the vent and the vent hose to make sure they
are clean and free of foreign material.
Axle Shaft Seals
Axle shaft oil seals are susceptible to the same kinds of damage as axle drive pinion seals if incorrectly
installed. The seal bore must be clean and the lip handled carefully to avoid cutting or tearing it. The
axle shaft journal surface must be free of nicks, gouges, and rough surface texture.
Differential Seals
Refer to Section 205 - 02A or
Section 205 - 02B .
Analysis of Vibration WARNING: A vehicle equipped with a Traction- Lok® differential will always have both
wheels driving. If only one wheel is raised off the floor and the rear axle is driven by the engine,
the wheel on the floor could drive the vehicle off the stand or jack. Be sure both rear wheels are
off the floor.
Few vibration conditions are caused by the rear axle. On a vibration concern, follow the diagnosis
procedure in Section 100 - 04 unless there is a good reason to suspect the axle.

GENERAL PROCEDURES
Hydro-
Boost Bleeding
1. NOTE: The Hydro- Boost power brake booster (2B560) is generally self- bleeding, and the
following procedure will normally bleed the air from the power brake booster. Normal operation
of the vehicle will further remove any additional trapped air.
Fill the power steering oil reservoir (3A697) with MERCON® Multi- Purpose ATF XT-2-QDX or
MERCON® equivalent.
2. Remove the powertrain control module (PCM) fuse to prevent the engine from starting.
3. Crank the engine for several seconds.
4. Check the fluid level in the power steering oil reservoir and add if necessary. Install the powertrain control module (PCM) fuse.
5. Start the engine.
6. With the engine running, turn the steering wheel (3600) from stop- to-stop twice. Turn the engine
off.
7. Depress the brake pedal (2455) several times to discharge the accumulator.
8. Repeat Steps 5 and 6.
9. If foaming occurs, stop the engine and allow the foam to dissipate.
10. Repeat Steps 5 and 6 as required, until all the air is removed from the system (when the foaming stops).

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.
