e. There are two la rge elongated holes in the cage
as well as four small holes. Turn the cage so the
two bosses in the spindle shaft will drop onto the
elongated holes and lift out the cage. See Fig. 225.
f. To remove the inner race, turn it so one of the
bosses will drop into an e longated hole in this cage
and shift the r ace to one side and lift it out.

M- 9. Ch ange in 4- Wh ee l Dri ve Front Axles
A change in design of the front axle of four-wheel
drive vehicles was placed in production effective
with Serial No. 37549 on Model CJ -3A. In the new
riesign the front axle shaft outer splined end floats
in the wheel driving flange and is not retained by a
nut and lockwasher as origin ally used. With this
construction it is no longer nec essary to install
s hims between the driving flange and wheel hub to
provide the correct end float of the axle shaft
univ er sal joint.

FIG. 22 4- DISMANTLING RZEPPA JOINT
The new construction, when using the Bendix type
ax le sha ft, is shown in Fig. 226. Note that the
en d float of the Bendix type joint is predetermined
in manufacture by the position and flange thickness
of the bushing and the thrust washer shown as
solid black areas in Fig. 226. These parts are so
positioned and of the correct thickness to pro-
vide .088" [2.24 mm.] maximum end float of
the universal joint and also to allow the center
point of the joint to operate at the center line of
the spindle pivot pins. Wi th the correct jo i nt end
float controlled by the bushing flange and the thrust
washer, it is no longer necessary to install shims
between the driving flange and wheel hub, a gasket
only being used.
The new type B endix axle shaft and universal joint
may be readily installed in an old type axle by
installing the new type fl anged bushing. When this
is done, discard the shims previous ly installed be -
tween the driving flange and wheel hub, installing
a gasket only. Th e installation of the flange bush-
ing will provide correct clearances and position of
the joint. The flanged bushing requires no reaming
as it is so designed that when it is pressed into the
spindle it will be compressed to provide correct
running clearanc e. Coat the inner surface of the
bushing with chassis grease before installing the
spindle.
The axle construction is similar for installation of
the Rzeppa joint, show n in Fig. 226 or the Spice r
J oint shown in Fig . 227. The thrust washer is not
necessary although it is installed in all axles to
allow installation of the Bendix type shaft if so
