All universal joints securing hardware
(bearing retainers and bearing retainers
bolts, spring tabs and bolts) must be
removed and replaced
using new OEM
specified replacement parts (Figure 1,
FIGURE 2).
When removing the universal joint from the
yoke,
the end caps must remain attached
to the cross at all times
if the universal
joint is to be reused (Electrical or masking
tape can be used to keep the end caps in
place while driveshaft is removed.)
Unless the universal joint is being replaced,
universal joint end caps
must not be
removed
for any reason. If the end caps
become dislodged while the driveshaft is
removed from the vehicle, the universal joint
must be replaced. If replacement is needed,
the universal joint
must be replaced as a
complete assembly
.
Universal
joints
must be treated as a
single unit
. This means that parts (such as
the cross, needle bearings, or end caps)
must not be interchanged
between new
and used joints.
Universal
joints
must be positioned and
seated correctly between the yoke tabs
(ears)
on the input (tail shaft side) and
carrier (differential side) yokes (FIGURE 26).
The driveshaft must be installed facing the
correct direction, in particular, with respect
to the splined slip joint.
The driveshaft must be phased correctly.
All fasteners must be torqued to
manufacturer's specifications and torque-
marked. DO NOT use air or power tools to
install and torque bolts or fasteners.
Bolt locking tabs, if used, must be bent over
the flats of the bolts after final torque is
checked.
The driveshaft guard (hoop) must be in
place.
Driveshaft universal joints must be greased
properly.
NOTE: If necessary, rotate driveshaft to allow
access to all grease fittings.
It is the responsibility of the maintainer who
begins the driveshaft installation to complete
the procedure in its entirety.
The
installation procedure must not he
carried over (passed on) to the next shift.
Supervisors must witness and verify the correct
installation of the driveshaft as follows:
The universal joint caps must be seated
properly between the yoke tabs (ears)
(FIGURE 26).
All universal joint bearing retainers must
have been replaced using new hardware
and fasteners.
All fasteners have been torqued properly
and are torque-marked.
Locking tabs, if used, must be bent over the
bolts.
There must be no mixing of new and old
parts on a universal joint.
The driveshaft must be phased properly.
Driveshaft guard (hoop) must be in place.
Driveshaft universal joints must be greased
after reinstallation of driveshaft in vehicle
