7. Set a suitable jack to rear final drive assembly.
CAUTION:
Do not place a suitable jack on the rear cover (aluminum
case).
8. Remove the mounting bolts and nuts connecting to the suspen-
sion member, and remove rear final drive assembly with a power
tool.
CAUTION:
Secure rear final drive assembly to a suitable jack while
removing it.
INSTALLATION
Note the following, and installation is in the reverse order of removal.
Refer to RFD-16, "COMPONENTS" about each tightening torque.
When installing breather hoses (1), refer to the figure.
CAUTION:
Make sure there are no pinched or restricted areas on the
breather hose caused by bending or winding when install-
ing it.
–For installation, the vehicle side end shall be inserted to suspen-
sion member (2). Install metal connector (3) side of this hose to
rear cover by inserting it with aiming painted marking to the front
of vehicle.
When oil leaks while removing final drive assembly, check oil
level after the installation. Refer to RFD-9, "
Checking Differential
Gear Oil" .

REAR FINAL DRIVE ASSEMBLY
Revision: 2006 January2006 M35/M45
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 the 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.
Do not insert flat-bladed screwdriver, this way damage
the mating surface.
5. Using two 45 mm (1.77 in) spacers, mount carrier on the attach-
ment.
6. For proper reinstallation, paint matching marks on one side of
the bearing cap.
CAUTION:
For matching marks, use paint. Do not damage bearing
caps and gear carrier.
Bearing caps are line-board during manufacture. The
matching marks are used to reinstall them in their origi-
nal positions.Runout limit: 0.08 mm (0.0031 in)

10. For proper reinstallation, paint matching marks on one differen-
tial case assembly.
CAUTION:
For matching marks, use paint. Do not damage differential
case and drive gear.
11. Remove drive gear mounting bolts.
12. Tap drive gear off differential case assembly with a soft hammer.
CAUTION:
Tap evenly all around to keep drive gear from bending.
13. Remove lock pin of pinion mate shaft with a punch from drive
gear side.
14. Remove pinion mate shaft.
15. Turn pinion mate gear, then remove pinion mate gear, pinion
mate thrust washer, side gear and side gear thrust washer from
differential case.
Drive Pinion Assembly
1. Remove differential assembly. Refer to RFD-22, "Differential Assembly" .

2. Using feeler gauge, measure the clearance between side gear
back and differential case at 3 different points, while rotating
side gear. Average the 3 readings, and then measure the clear-
ance of the other side as well.
CAUTION:
To prevent side gear from tilting, insert feeler gauges with
the same thickness from both sides.
3. If the back clearance is outside the specification, use a thicker/
thinner side gear thrust washer to adjust. Refer to RFD-38,
"Side Gear Thrust Washer" .
CAUTION:
Select a side gear thrust washer for right and left individu-
ally.
Side Bearing Preload
Selecting carrier side bearing adjusting washers is required for successful completion of this procedure.
1. Make sure all parts are clean. Also, make sure the bearings are
well lubricated with gear oil.
2. Place the differential case, with side bearings and bearing races
installed, into gear carrier.
3. Insert left and right original side bearing adjusting washers in
place between side bearings and gear carrier.Side gear back clearance specification:
0.2 mm (0.008 in) or less.
(Each gear should rotate smoothly without excessive
resistance during differential motion.)
When the back clearance is large:
Use a thicker thrust washer.
When the back clearance is small:
Use a thinner thrust washer.

4. Install bearing caps in their correct locations and tighten bearing
cap mounting bolts to the specified torque. Refer to RFD-18,
"COMPONENTS" .
5. Turn the carrier several times to seat the bearings.
6. Measure the turning torque of the carrier at the drive gear
mounting bolts with a spring gauge.
7. If the turning torque is outside the specification, use a thicker/
thinner side bearing adjusting washer to adjust. Refer to RFD-
38, "Side Bearing Adjusting Washer" .
CAUTION:
Select a side bearing adjusting washer for right and left
individually.
8. Record the total amount of washer thickness required for the correct carrier side bearing preload.
Pinion Gear Height
1. Make sure all parts are clean and that the bearings are well
lubricated.
2. Assemble the pinion gear bearings into the differential shim
selector tool.
