\fl CAUTION:
VI 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
The rear axle assembly is of the semi-floating type in
which the vehicle weight is carried on the axle
housing (Fig. 48-1).
The center
line of the pinion gear is below the center
line of the ring gear (hypoid drive).
All parts necessary to transmit power from the
propeller shaft to the rear wheels are enclosed in a
banjo type axle housing.
The 8.7 inch ring gear rear axle uses a conventional
ring and
pinion gear set to transmit the driving force
of the engine to the rear wheels. This gear set transfers
this driving force at a 90 degree angle from the
propeller shaft to the drive shafts. The
axle shafts
are supported at the wheel end of the
shaft by a roller bearing.
The
pinion gear is supported by two tapered roller
bearings. The pinion depth is set by a shim pack
located between the gear end of the pinion and the
roller bearing that is pressed onto the pinion. The
pinion bearing preload is set by crushing a collapsible
spacer between the bearings in the axle housing.

Repeat
the procedure to verify the "0"
setting.
