Test Step Result / Action to Take
M1 INSPECT THE TRANSFER CASE
z
WARNING: The electrical power to the air suspension
system must be shut off prior to hoisting, jacking or towing
an air suspension vehicle. This can be accomplished by
turning off the air suspension switch. Failure to do so can
result in unexpected inflation or deflation of the air springs,
which can result in shifting of the vehicle during these
operations.
z Inspect the transfer case for loose or missing mounting bolts.
Check for fluid seepage between the transfer case and the
transmission.
z Are the mounting bolts missing or loose? Yes
TIGHTEN to
specifications or
INSTALL new bolts as
necessary. TEST the
system for normal
operation.
No
GO to
M2 .
M2 INSPECT THE REAR DRIVESHAFT
z
NOTE: Verify that the driveshaft and pinion flange index marks
are aligned.
z Inspect the driveshaft for missing weights, damage or
undercoating.
z Inspect the U- joints for freedom of movement.
z Check driveshaft runout and, if necessary, check the pinion
flange runout.
z Is the driveshaft or U- joints worn or damaged or
misaligned? Yes
REPAIR or INSTALL a
new driveshaft as
necessary. TEST the
system for normal
operation.
No
GO to
M3 .
M3 CHECK THE DRIVELINE ANGLES
z
Measure the rear driveshaft and pinion angles. Refer to Section 205 - 00 .
z Measure the front driveshaft and pinion angles. Refer to Section 205 - 00 .

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 must be installed if installation becomes necessary. If substitution is
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. Remove the rear wheel knuckle (5A968/5A969). For additional information, refer to Wheel Knuckle — Cobra in this section.
2. Remove the bolts and the dust shield. Discard the bolts.
3. Position the knuckle in a vise.
4. NOTE: There are two methods for removing the rear hub (1109) from the rear wheel bearing
(1A049). Both methods are shown.
Method one. Using the special tools, remove the hub. Step Plate Adapter Set

CAUTION: The bearing inner race must be supported during hub installation.
Failure to follow these instructions can damage the bearing.
Install the hub. 1. Position the knuckle in a press, making sure the wheel bearing inner race is supported with the appropriate step plate adapter.
2. Using the special tool, install the hub. 4. Install the dust shield and new bolts. Klj . 4 ba

CAUTION: Align the index marks on the driveshaft centering socket yoke and the
pinion flange.
CAUTION: Install the driveshaft with new bolts. If new bolts are not available, apply
Threadlock and Sealer EOAZ-19554- AA or equivalent meeting Ford specification WSK-
M2G351- A5 to the threads of the original bolts.
CAUTION: The driveshaft centering socket yoke fits tightly on the pinion flange
pilot. To make sure that the yoke seats squarely on the flange, tighten the bolts evenly in
a cross pattern as shown.
CAUTION: Raise the suspension to the reference marks on the rear shock
absorbers before tightening the suspension fasteners.
NOTE: Apply High Temperature Nickel Anti- Sieze Lubricant F6AZ-9L494-AA meeting Ford
specification ESE-M124A- A to the rear anti-lock brake sensor body where it will make contact
when installed.
To install, reverse the removal procedure.
