4. Remove bolt, nut and washer (Front axle side).
5. Remove bolt, nut and washer (Transfer side).
6. Remove front propeller shaft.
NOTE: If equipped with torque on demand (TOD), when
removing, installing or carring for front propeller shaft, be
sure to wind a piece of cloth round the part of the boot with
which fittings may interfere so that the boot can be
protected. The boot may be damaged if bending force is
applied to the constant velocity joint of the shaft.

Installation
NOTE: Never install the shaft assembly backwards.
Completely remove the black paint from the connecting
surface of flange coupling on each end of propeller shaft.
Clean so that no foreign matter will be caught in between.
1. Align the mark which was applied at removal. Install
front propeller shaft and tighten the bolts to the
specified torque.
Torque: 63 N´m (6.4 kg´m/46 lb ft)
2. Install the exhaust and transfer protectors.
3. After installing the propeller shaft, be sure to apply
black paint (1) to exposed area (other than
connecting surface) of the entire surface of flange
coupling .

Constant Velocity Joint
NOTE: L J a n d B J constant velocity joints are
unremovable types. Check the joint for play and the boot
for damage, wear, and leak of grease. If abnormality is
found, replace propeller shaft as an assembly.
Play in Constant Velocity Joint
Fix the shaft in a vise throrgh pieces of wood, and try to
move the joint vertically, right and left, and back and forth
to make sure of smooth motions and no remarkable play.

•Insert a block of wood into the caliper and force
out the piston by blowing compressed air into the
caliper at the flexible hose attachment. This
procedure must be done prior to removal of dust
boot.
WARNING:
DO NOT PLACE YOUR FINGERS IN FRONT OF THE
PISTON IN AN ATTEMPT TO CATCH OR PROTECT IT
WHEN APPLYING COMPRESSED AIR. THIS COULD
RESULT IN PERSONAL INJURY.
CAUTION:
Use just enough air to ease the piston out of the
bore. If the piston is blown out, it may be damaged.
