PROPELLER SHAFT PROPELLER SHAFT ASSEMBLY
1996 LAND CRUISER (RM451U)
INSPECTION
1. INSPECT FRONT AND REAR PROPELLER SHAFTS FOR DAMAGE OR RUNOUT
Using a dial indicator, check the runout of shafts. Maximum runout: 0.8 mm (0.031 in.)
If shaft runout is greater than maximum, replace the shaft.
2. REMOVE SLEEVE YOKE FROM PROPELLER SHAFT
Place matchmarks on the sleeve yoke and shaft.
(1) Pull out the sleeve yoke from the shaft.
(2) Remove the dust cover from the shaft.
3. INSPECT SPIDER BEARING
Check the spider bearings for wear or damage.
Check the spider bearing axial play by turning the yoke
with holding the shaft tightly.
Bearing axial play: Maximum 0.05 mm (0.0020 in.)
If necessary, replace the spider bearing.
4. INSERT SLEEVE YOKE INTO PROPELLER SHAFT
(a) Apply MP grease to the propeller shaft spline and sleeve yoke sliding surface.
(b) Align the matchmarks on the sleeve yoke propeller shaft.
(c) Install the propeller shaft into the sleeve yoke.

TROUBLESHOOTING
PROBLEM SYMPTOMS TABLE
Use the table below to help you find the cause of the problem. The numbers \
indicate the priority of the likely
cause of the problem. Check each part in order. If necessary, replace these parts.
(w/ Differential locking system):
Check that center differential lock mode is set.
When switching differential Free↔Lock, the indicator lamp will blink if the gears of the differen-
tial lock sleeve are not meshed. If this occurs, when the tires are rotated \
to apply differential
power to the differential, the differential locks and the indicator lamp\
light up.

DISASSEMBLY
1. CHECK RUNOUT OF COMPANION FLANGE
Using a dial indicator, measure the vertical and lateral runout of
the companion flange. Maximum runout: 0.10 mm (0.0039 in.)
2. CHECK RING GEAR RUNOUT
Using a dial indicator, measure the ring gear runout. Maximum runout: 0.10 mm (0.0039 in.)
If the runout is greater than the maximum, replace the ring gear
and driven pinion as a set.
3. CHECK RING GEAR BACKLASH
Using a dial indicator, measure the ring gear backlash. Backlash: 0.13 −0.18 mm (0.0051 −0.0071 in.)
If the backlash is not within the specification, adjust the side
bearing preload or repair as necessary.
4. MEASURE DRIVE PINION PRELOAD
Using a torque wrench, measure the preload of backlash be-
tween the drive pinion and ring gear. Preload (at starting):
0.5 − 0.8 N·m (5 − 8 kgf·cm, 4.3 − 6.9 in.·lbf)
5. CHECK TOTAL PRELOAD
Using a torque wrench, measure the preload. Total preload (at starting):
Drive pinion preload plus
0.4 − 0.6 N·m (4 − 6 kgf·cm, 3.5 − 5.2 in.·lbf)
If necessary, disassemble and inspect the differential.

6. w/o DIFFERENTIAL LOCK:
CHECK SIDE GEAR BACKLASH
Using a dial indicator, measure the side gear backlash with
holding one pinion gear toward the case.
Backlash: 0.05 − 0.20 mm (0.0020 − 0.0079 in.)
If the backlash is not within the specification, install the correct
thrust washers (See page .SA−35 ).
7. CHECK TOOTH CONTACT BETWEEN RING GEAR AND DRIVE PINION (See page SA−35 )
8. w/ DIFFERENTIAL LOCK: REMOVE ACTUATOR
(a) Remove the bolt and actuator from the differential carrier.
(b) Remove the O−ring.
9. w/ DIFFERENTIAL LOCK: REMOVE INDICATOR SWITCH
Remove the indicator switch and gasket.
10. w/ DIFFERENTIAL LOCK:
REMOVE SHIFT FORK SHAFT
(a) Using a hexagon wrench, remove the 2 straight screw plugs.
(b) Remove the spring seat, compression spring and ball.
(c) Using a pin punch and hammer , remove the slotted spring
pin.
(d) Remove the 2 bolts from the shaft retainer.
(e) Using a plastic hammer, tap out the shaft retainer.
(f) Remove the shift fork shaft.
HINT:
Pull out the shift fork shaft with a screwdriver turned round.
