4C±37 DRIVE SHAFT SYSTEM
Front Propeller Shaft
General Description
Since the propeller shaft is balanced carefully, welding or
any other modifications are not permitted.Alignment marks should be applied to each propeller
shaft before removal.

Removal
1. Jack up the vehicle and support it on the chassis
stands.
2. Gear shift lever should be placed in neutral position
and parking brake released.
3. Remove the exhaust and transfer protectors.
NOTE: Apply alignment marks on the flange at the front
propeller shaft both front and rear side.

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.
401RW051
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 .

3. Make sure of proper position for reinstallation by
applying setting marks, then remove spider .
Inspection and Repair
Make necessary correction or parts replacement if wear,
damage, corrosion or any other abnormal condition is
found through inspection.
NOTE: When any part of the journal assembly (spider,
needle roller bearing) requires replacement, be sure to
replace the entire assembly.
Check the following parts for wear, damage, noise or any
other abnormal conditions:
1. Spider
2. Needle roller bearing
3. Yoke
4. Flange
5. Constant velocity joint
Outside Diameter of Spider Pin
Standard: 17.00 mm (0.669 in)
Limit: 16.90 mm (0.665 in)
401RS007
Propeller Shaft Run±out
Support the ends of the propeller shaft on V-blocks (2)
and check for run±out by holding the probe of a dial
indicator (1) in contact with the center part of the shaft. If
the amount of run±out is beyond the standard value for
assembly, correct with a bench press or replace the shaft
with a new propeller shaft assembly.
Standard: 0.3 mm (0.012 in)
Limit: 0.5 mm (0.02 in)
401RS027
Play in Splines in Normal Direction of
Rotation
Check the amount of play between the sleeve yoke (1)
and the propeller shaft spline (2) in the direction of
rotation, using a pointed feeler gauge.
Standard: 0.073 ± 0.156 mm (0.003 ± 0.006 in)
Limit: 0.3 mm (0.012 in)

Play in Universal Joint
Limit: Less than 0.1 mm (0.004 in)
401RS010
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.
401RW050
401RW049
Boot of Constant Velocity Joint
Check the boot (2) for crack, damage and grease leak,
and the boot band (1) for loosening and damage. Check
the both sides of the joint and make sure that there is no
leak of grease from the cover press-in parts(3).

Front Axle Flange Run-out
1. Set a dial gage at right angle near the outer
circumference of the flange face and check the
run-out of the flange face.
Limit: 0.15 mm (0.006 in)
401RW046
2. Set a dial gage at right angle near the inner
circumference and check the run-out of the flange.
Limit: 0.15 mm (0.006 in)

3. If vibration is felt during the 4H AUTO drive, disconnct
the propeller shaft at the front axle. Reinstall the
propeller shaft at 60
, 120
, 180
, 240
, and 300

and conduct test drive in each position and check if
there is vibration.
