'f CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were removed.
If a fastener needs to be replaced, use the correct part number fastener for that application. If the correct
part
number fastener is not available, a fastener of equal size and strength (or stronger) may be used.
Fasteners
that are not reused, and those requiring thread locking compound, will be called out. The
correct
torque values must be used when installing fasteners that require torque. If the above conditions
are not followed, parts or system damage could result.

GENERAL DESCRIPTION
This publication contains essential removal, instal­
lation,
adjustment and maintenance procedures.
The
front axle utilizes a central disconnect type front
axle/transfer case system. The
drive axles are completely flexible assemblies,
consisting
of inner and outer constant velocity (CV)
drive shaft joints connected by an axle shaft. For
description
of front propeller shaft and universal
joint, refer to Section 4A "PROPELLER SHAFT".

w CAUTION:
• All
brake attaching fasteners are an important attaching part in that they could affect performance of vital
parts and systems, and/or could result in major repair expense. They must be replaced with one of the same
part
number or with an equivalent part if replacement becomes necessary. Do not use replacement parts of
lesser quality or substitute design. Torque values must be used as specified during reassembly to assure
proper retention
of these parts.
