REAR PROPELLER SHAFT
 Inspect propeller shaft runout at measuring points. If runoutexceeds specifications, replace propeller shaft assembly. For mea-
suring point, refer to PR-4, "
On-Vehicle Inspection".
 As shown in the figure, while fixing yoke on one side, check axial play of joint. If outside the standard, replace relevant propeller
shaft.
 Check propeller shaft for bend and damage. If damage is detected, replace relevant propeller shaft.
CAUTION:
Never disassemble joints.
 Check center bearing for noise and damage. If noise or damage is
detected, replace center bearing. Refer to PR-11, "
Disassembly
and Assembly of Center Bearing".
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Avoid damaging the rebro joint boot, protect it with a shop towel or equivalent.
 Align matching marks to install propeller shaft to final drive and transfer (AWD models only) companion
flanges, and then tighten to specified torque. Refer to PR-8, "
Component".
 Install center bearing mounting bracket (Upper) with its arrow mark
facing forward.
 Adjust position of mounting bracket sliding back and forth to pre- vent play in thrust direction of center bearing insulator. Install
bracket to vehicle.
 After assembly, perform a driving test to check propeller shaft vibration. If vibration occurred, separate propeller shaft from final
drive. Reinstall companion flange after rotating it by 60, 120, 180,
240, 300 degrees. Then perform driving test and check propeller
shaft vibration again at each point.
 If propeller shaft or final drive has been replaced, connect them as follows: Propeller shaft runout limit : 0.8 mm (0.031 in)

2. Remove side flanges.
3. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
4. Rotate drive pinion at least 20 times to check for smooth operation of the bearing.
5. Measure total preload with the preload gauge.
NOTE:
Total preload torque = Pinion bearing preload torque + Side
bearing preload torque
 If measured value is out of the specification, disassemble it to
check and adjust each part. Adjust the pinion bearing preload and
side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.
Drive Gear Runout
1. Remove rear cover. Refer to "Differential Assembly".
2. Fit a dial indicator to the drive gear back face.
3. Rotate the drive gear to measure runout.
 If the runout is outside of the repair limit, check drive gear assem- bly condition; foreign material may be caught between drive gear
and differential case, or differential case or drive gear may be
deformed, etc.
CAUTION:
Replace drive gear and dri ve pinion gear as a set.

When the preload torque is largeOn pinion bearings: Replace the collapsible spacer.
On side bearings: Use thinner side bearing adjusting washers by the same amount to
each side. Refer to RFD-38, "

REAR FINAL DRIVE ASSEMBLY
Never change the total amount of washers as it will change the bearing preload.
Companion Flange Runout
1. Fit a test indicator to the inner side of companion flange (socket
diameter).
2. Rotate companion flange to check for runout.
3. If the runout value is outside t he runout limit, follow the proce-
dure below to adjust.
a. Check for runout while changing the phase between companion flange and drive pinion by 90 ° step, and search for the position
where the runout is the minimum.
b. If the runout value is still outside of the limit after the phase has been changed, possible cause will be an assembly malfunction of drive pinion and pinion bearing and
malfunction of pinion bearing. Check for these items and repair if necessary.
c. If the runout value is still outside of the limit after the check and repair, replace companion flange.
DISASSEMBLY
Differential Assembly
1. Drain gear oil, if necessary.
2. Remove side flange.
3. Remove rear cover mounting bolts.
4. Remove rear cover to insert the seal cutter between gear carrier and rear cover.
CAUTION:
 Be careful not to damage the mating surface.
 Never insert flat-bladed screwdriver, this way damage the
mating surface.

8. Using the drift, install front oil seal as shown in figure.
CAUTION:
 Never reuse oil seal.
 When installing, never incline oil seal.
 Apply multi-purpose grease onto oil seal lips, and gear oilonto the circumference of oil seal.
9. Install companion flange (1). NOTE:
When reusing drive pinion, align the matching mark (B) of drive
pinion with the matching mark (A) of companion flange, and then
install companion flange (1).
10. Apply anti-corrosion oil to the thread and seat of drive pinion lock nut, and temporarily tighten drive pinion lock nut to drive pinion.
CAUTION:
Never reuse drive pinion lock nut.
11. Adjust to the drive pinion lock nut tightening torque and pinion bearing preload torque.
CAUTION:
 Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
 If the preload torque exceeds the specified value, replace collapsible spacer and tighte n it again to adjust. Never
loosen drive pinion lock nut to adjust the preload torque.
 After adjustment, rotate dri ve pinion back and forth 2 to 3
times to check for unusual no ise, rotation malfunction,
and other malfunctions.
