GENERAL PROCEDURES
Driveline Angle Inspection
NOTE:
An incorrect driveline angle can cause a vibration or shudder. For additional information, refer
to Section 100 - 04 .
1. Check the vehicle for evidence or overload or sagging. Check for specified air pressures information in all four tires.
2. Normalize the suspension.
3. Drive the vehicle onto a drive- on hoist or back onto a front-end alignment rack.
4. Inspect the suspension and chassis. Verify that the vehicle curb position ride height is within specification. For additional information, refer to Section 204 - 00 .
z Measure the curb position ride height with the vehicle empty and all fluids full.
5. Place the Inclinometer flush against the bottom of the driveshaft. After the tool has been held on the driveshaft surface for 5 seconds, push the ALT ZERO button to calibrate to zero degrees.
Remove the tool.
6. To check the pinion angle, rotate the driveshaft so that the rear axle pinion flange yoke ear is parallel to the floor. Remove the U- joint snap ring, then install the special tool. Check and record
the pinion angle reading.
zIf the angle is not within specification, repair or adjust to obtain the correct angle. Inspect
the rear suspension, rear axle, rear axle mounting or the frame for wear or damage.

GENERAL PROCEDURES
Axle Housing Casting Porosity (Holes in Casting) Repair
CAUTION: To keep the axle's sound characteristics, do not disassemble the carrier.
NOTE: Casting porosity is a condition where occasionally gas bubbles will form during the casting
process leaving small pockets in the metal that will cause the axle housing to leak.
1. To fill small pockets, peen in a small amount of body lead.
2. Seal the pocket. zUse epoxy sealer meeting Ford specification M- 3D35A(E).
3. To fill large pockets, drill and tap a shallow hole for a small setscrew. Install the setscrew and seal it.
zUse epoxy sealer meeting Ford specification M- 3D35A(E).

GENERAL PROCEDURES
Axle Housing Weld Leaks Repair
1. CAUTION: To keep the axle's sound characteristics, do not disassemble the carrier.
CAUTION: Rear axle housing straightness is too critical for field repair. Install a new
axle housing if a weld is broken.
NOTE: Most minor weld leaks are repairable. This includes the puddle and fill welds that join
the axle shaft tube to the axle housing on integral axles.
Seal the weld.
zUse Devcon Aluminum Liquid F2 or equivalent meeting Ford specification M- 3D35A(E).

VEHICLE REPAIR
Axle Housing Bushing
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 upper arm and bushing (5500). For additional information, refer to Section 204 - 02 .
2. Using the special tools, remove the bushing.
Installation 1. Using the special tools, install the bushing.

2. Raise and support the vehicle. For additional information, refer to
Section 100 - 02 .
3. Remove the rear wheel and tire assemblies. For additional information, refer to Section 204 - 04 .
4. Remove the exhaust system. For additional information, refer to Section 309 - 00 .
5. Remove the pinion nose crossmember.
6. CAUTION: Index- mark the driveshaft flange and rear axle pinion flange (4851) to
maintain initial balance during installation.
CAUTION: The driveshaft centering socket yoke fits tightly on the rear axle pinion
flange pilot. Never hammer on the driveshaft (4602) or any of its components to
disconnect the yoke from the flange. Pry only in the area shown, with a suitable tool, to
disconnect the yoke from the flange.
Disconnect and position the driveshaft out of the way.

DESCRIPTION AND OPERATION
Rear Drive Halfshafts
The rear wheel drive halfshaft system consists of and operates as follows:
zHalfshafts (4K138) transmit engine torque from the rear axle housing to the rear wheels.
z Halfshafts rotate at approximately one- third the speed of a driveshaft and do not contribute to
rotational vibration disturbances.
z A constant velocity (CV) joint is a mechanism for transmitting uniform torque and rotary motion
while operating through a range of angles.
z CV joints at both inboard (differential) and outboard (wheel) ends provide operating
smoothness.
z The inboard CV joints are plunge- type joints that provide the axial movement necessary to
affect shaft length changes.
z The outboard CV joints have a higher angle capability than the inboard CV joints to
accommodate suspension travel.
z Inboard and outboard CV joints connect to a splined shaft.
z A driveshaft bearing retainer circlip retains the splined inboard CV joint to the differential side
gear. Install a new circlip every time you remove the halfshaft from the vehicle.
z A rear axle wheel hub retainer secures the interconnecting shaft and outboard CV joint to the
rear hub.
z The lubed-for- life CV joints use special CV joint grease. They require no periodic lubrication.
z To separate the halfshaft from the rear hub, press the outboard CV joint from the rear hub.
z To separate the halfshaft from the differential, apply a load to the back face of the inboard CV
joint assembly to overcome the circlip.
z The halfshaft assemblies are not repairable. Install a new assembly if worn/damaged.
