Axles, Drive Shafts, Wheels and Tires
5.4.6 Drive Shaft Assembly
1. Install the dust cap (Fig. 5-13, 7), split retaining ring
(8), and felt seal (9) onto the splines of the drive
shaft tube assembly.
IMPORTANT: Ensure that the reference marks made
before removal on the drive shaft and slip yoke are
aligned. The drive shaft and yokes must be in the same
plane to help prevent excessive vibration.
2. Align the reference marks made before removal on
the drive shaft and slip yoke.
3. Slide the slip yoke (Fig. 5-13, 5) onto the splines of
the drive shaft and tighten the dust cap (Fig. 5-13, 7)
securely. DO NOT overtighten or the cap will break.
4. Install the cross and bearing assembly into the yoke.
5. Secure the cross and bearing assembly into the
yoke with snap rings (Fig. 5-13, 1). Pinch each snap
ring with a pliers and insert them into their grooves in
the yoke.
6. Apply grease to grease fitting (Fig. 5-13, 10). (Refer
to Section 2.6.7, “Drive Shaft Splines.”)
5.4.7 Drive Shaft Installation
IMPORTANT: To help ensure optimum performance, the
drive shaft assemblies are specially balanced as a unit at
the factory. When servicing any flange yoke, slip yoke, or
drive shaft tube, order a complete assembly if compo-
nents are bent or damaged. Refer to the appropriate
parts manual for ordering information.
a. Transmission-to-Axle Drive Shafts
1. Level the vehicle, ground the carriage, place the travel
select lever in the (N) NEUTRAL position, place the
neutral lock lever in the (N) NEUTRAL LOCK
position, engage the parking brake switch and shut
the engine OFF.
2. Place an Accident Prevention Tag on both the
ignition key switch and steering wheel, stating that
the vehicle should not be operated. (Refer to Section
1.5, “Accident Prevention Tag Usage.”)
3. Unlock and open the right and left engine
compartment access doors. Allow the engine,
transmission and hydraulic fluid to cool.
4. Disconnect the battery negative (-) cable at the
battery negative (-) terminal, to prevent the engine
from starting accidentally.
5. Raise the drive shaft assembly (Fig. 5-14, 1) into
position. The slip yoke-end of the drive shaft mounts
toward the axle. If reinstalling a drive shaft previously
removed, align the flange yokes according to the
alignment marks made during removal.
IMPORTANT: Yokes at both ends of the drive shaft must
be in the same plane to help prevent excessive vibration.
6. Install the four hex-head capscrews (Fig. 5-14, 2)
and two straps (3) securing the bearing crosses to
the transmission. Torque the capscrews to 60 lb/ft (81
Nm).
7. Install the four hex-head capscrews (Fig. 5-14, 4)
and two straps (5) securing the bearing crosses to
the axle. Torque the capscrews to 60 lb/ft (81 Nm).

8. Connect the negative (-) battery cable.
b. Engine-to-Transmission Drive Shaft
1. Level the vehicle, ground the carriage, place the travel
select lever in the (N) NEUTRAL position, place the
neutral lock lever in the (N) NEUTRAL LOCK
position, engage the parking brake switch and shut
the engine OFF.
2. Place an Accident Prevention Tag on both the
ignition key switch and steering wheel, stating that
the vehicle should not be operated. (Refer to Section
1.5, “Accident Prevention Tag Usage.”)
3. Unlock and open the right and left engine
compartment access doors. Allow the engine,
transmission and hydraulic fluid to cool.
4. Disconnect the battery negative (-) cable at the
battery negative (-) terminal, to prevent the engine
from starting accidentally.
