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 Tags.”)

compartment access doors. Allow the engine,
transmission and hydraulic fluid to cool.

6. The drive shaft assembly is a balanced assembly.
Mark the yoke and axle, transmission and the shaft
and slip yoke so that these components can be
returned to their original positions when reinstalled.
Yokes at both ends of the drive shaft must be in the
same plane to help prevent excessive vibration.
7. Remove the four capscrews (8) and two straps (9)
securing the bearing cross to the transmission input
shaft flange.
8. Remove the four capscrews (10), four
lockwashers (11) securing the flange yoke (12) to the
engine output flange.
9. Remove the drive shaft assembly (13).
5.4.4 Drive Shaft Disassembly
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
components are bent or damaged. Refer to the
appropriate Parts Manual for ordering information.
a. Transmission-to-Axle Drive Shafts
1. Use an approved, non-flammable cleaning fluid to
thoroughly clean the drive shaft assembly with a
brush. Wipe dry before disassembling.
2. Place the drive shaft assembly in a bench vise.
3. Use a pair of pliers to pinch the ends of the snap
rings (14) securing the cross (15) and bearing (16)
assemblies to the yoke (17 or 18). Remove the snap
rings from their grooves in the yoke.
Note: If the snap rings fail to readily snap out of their
grooves in the yokes, tap the end of the bearing cap
lightly to help relieve pressure against the snap rings.

when clamping the drive shaft in a vise. Apply
only enough force to hold the drive shaft
securely. Excessive force can damage the
drive shaft, resulting in an unbalanced condition.
