5-7 INTRODUCTION
a. Arrangement and Use of This Section
This section contains procedures for repair
or replacement of all internal components of
the rear axle assembly except the brakes. The
procedures are arranged inthe progressive or-
der that should be followed for a complete
overhaul of the rear axle.
The procedures should be followed in the
order given, to the extent required to accom-
plish removal, inspection, installation, and ad-
justment of only those parts that are to be
repaired or replaced. Individual procedures are
given in separate numbered paragraphs to aid
in selecting the particular procedures required
when less than a
complete
overhaul is being
performed.
All procedures in this section will be required
for replacement of a ring and pinion gear set.
These parts are furnished in matched sets
only; individual gears are not available. The
matched sets are furnished separately and also
with the ring gear riveted to a differential case.
b. When to Remove Rear Axle Assembly
On cars equipped with Syncro-Mesh trans-
missions, it is not necessary to remove the rear
axle assembly for any of the repairs outlined
in this section; however, these procedures can
be used as outlined if the assembly is removed
from the car.
The rear axle assembly should be removed
from the car before overhaul
(par.
5-26) if
there is external indication of damage to rear
axle or third member housings or strut rods,
or if oil is leaking at torque ball or third mem-
ber flanged
joints.
These conditions cannot be
corrected with the rear axle assembly under
the car.
On cars equipped with Dynaflow
Drive,
it is
necessary to remove
the
rear axle assembly
from car
whenever the
propeller shaft must be
r
emoved.
The propeller shaft spline oil seal
located on front end of propeller shaft (fig.
5-33) cannot be properly installed with third
member housing connected to the torque ball.
