2. FULLY TIGHTEN PROPELLER W/CENTER BEARING
SHAFT ASSEMBLY
(a) Remove the cloth from the joint.
(b) Using a hexagon wrench (6 mm), tighten the 6 bolts.
Torque: 29 N*m (296 kgf*cm, 21 ft.*lbf)
(c) With the vehicle unloaded, adjust the dimension
between the rear side of the cover and shaft, as
shown in the illustration.
(d) Adjust the front and rear dimensions between the
edge surface of the center support bearing and the
edge surface of the cushion to 12.5 +- 1.0 mm
(0.492 +- 0.039 in.) respectively as shown in the
illustration, then torque the bolts.
Torque: 37 N*m (375 kgf*cm, 27 ft.*lbf)
(e) Check that the center line of the bracket is at right
angles to the shaft axial direction.
(f) If any vibration or noise occurs, perform joint angle
check as follows and replace the adjusting shim with
a proper one.
(1) Turn the propeller shaft several times by hand
to stabilize the center support bearings.
(2) Using a jack, raise and lower the differential to
stabilize the differential mounting cushion.
(3) Remove the transfer dynamic damper.
(4) Using SST(s), measure the installation angle of
the transfer extension housing (A) and front
propeller shaft (B).

EX-8)
3. SEPARATE REAR SPEED SENSOR
(a) Remove the bolt and the speed sensor from the
axle carrier.
NOTICE:
• Be careful not to damage the speed sensor.
• Prevent foreign matter from adhering to the
speed sensor.
4. REMOVE REAR AXLE SHAFT NUT
(a) Using SST and a hammer, unstake part of the axle
shaft nut.
SST 09930-00010
NOTICE:
Loosen the staked part of the nut completely,
otherwise the screw of the drive shaft may be
damaged.
(b) While apply the brakes, remove the axle shaft nut.
5. REMOVE REAR DRIVE SHAFT ASSEMBLY LH
(a) Place matchmarks on the drive shaft and differential
side gear shaft.
(b) Remove the 4 nuts and washers, and disconnect

6. SECURE REAR AXLE ASSEMBLY
NOTICE:
• After disconnecting the drive shaft from the axle
hub, work carefully so as not to damage the ABS
speed sensor rotor serration on the drive shaft.
• The hub bearing could be damaged if it is
subjected to the vehicle weight, such as when
moving the vehicle with the drive shaft removed.
Therefore, if it is absolutely necessary to place
the vehicle weight on the hub bearing, first
support it with SST.
