9. Install the differential side bearing by press.
Use the press machine and special tools to install the side bearing
on the differential housing by press.
10. Install the differential assembly
a.Remove the bearing gland. Do not mix the left up with right.
b.Install the differential assembly in the reducer housing.
11.Install the adjusting ring
Use the adjusting ring to press the bearing outer race in position;
tighten it properly. Adjust the clearance between the drive and
driven gear to the proper dimension.
12. Install the bearing gland
a. Align the assembly mark on the bearing cover with that on re
ducer housing; Press down the press cover by hand.
b. Install the lock washer with double ears and nut; tighten the
hexagon nut by pneumatic wrench properly.
13. Adjust the engagement clearance between the drive
and driven gear.
a. Use the torque wrench to tighten four bolts on bearing cover by
torque wrench.

15. Install the stop washer and stop plate
a. If the drive and driven gear engagement mark meets the requirement,
then use the hand hammer and punch to lock the stop washer.
b. Install the stop plate, spring shim and bolt; tighten the bolt.
Tightening force: 18-25N

16. Measure the total pre-applied load
Pre-applied load : 1.8-2.4Nm
If the pre-applied load is beyond the specified; it should replace the
shim between the spacer and rear bearing until meet the requirement.
a. It should replace the adjusting washer if the pre-applied load is
more than specified value.
b. If the pre-applied load is less than specified value, it can retighten
the nut slowly and the torque should be no more than 160N
m.
Caution: When tighten the nut, if is beyond the Max. torque, re-
place the adjusting washer and repeat the pre-applied load process.
Do not reduce the pre-applied load by the method of screw off the
drive gear nut to loose.

17. Check and adjust the run-out of flange.
a.Adhere the dial indicator base on the reducer housing; make the
probe of dial indicator contact with the end surface of flange;
rotate the flange and watch the rotation range of the dial.
Full run-out tolerance of end surface: 0.10mm
b.Adhere the dial indicator base on the reducer housing; make the
probe of the dial indicator contact with the inner diameter of
flange; rotate the flange by hand , and watch the rotation range of
the dial.Radial full run-out tolerance: 0.10mm
18. Rivet the nut of drive bevel gear
Installation of reducer and differential assembly
1.Install the new stiffening ring
2.Install the reducer and differential assembly
Install the reducer and differential assembly in the rear axle housing;
place the washer and nut. Tighten the nut to the specified torque.
Tightening force: 18-25N
m
3.Install the reducer and differential assembly flange
on the drive shaft flange and align the assembly
mark; use four bolts and nuts to connect them.
Tighten the bolt and nut to the specified torque.
Tightening force: 78

4.Install the oil drain plug; fill the differential with the
gear oil
oil number : GL-5 hyperbolic gear oil
Viscosity: SAE80W/90
Amount: Filled with oil until the oil flow out from the oil filling
port.
Tighten the oil filling plug.

Removal of vibration damper
1. Use the lifter to raise the car firstly, then support
the rear axle by bracket.
2. Remove the upper and lower fixing nut which is used
to fix the vibration damper; compress the vibration
damper by hand.
Remove the upper end firstly, then the
lower end; take out the vibration damper .
Installation of vibration damper:
1. Lower tightening force of vibration damper:
170
5Nm.
Upper tightening torque : Compress the rubber block to 2/3 of
total height.
Caution: If the fixing nut of vibration damper is the lock nut, it
should be replaced by the new lock nut after replace the vibra-
tion damper.
Removal of coil spring:
1
. Remove the vibration damper (As previous )
2. Use the special tools to clamp the coil spring.
3. Place the car in the bounce status, take out the
coilspring
4. Remove the special tools from the coil spring.
Installation of coil spring:
1. Firstly, use the special tools to clamp the coil spring
to certain height (height when car is in bounce
status).
2. Cautions for installation: Adjust the rubber gasket on
the spring to ensure the spring in flat status.
3. Remove the special tools.special tools

Removal of connecting rod of stabilizer bar:
1.Shown as figure, firstly screw off the nut in the con
necting place between the connecting rod of stabi
lizer bar and carriage. (Need the inner hexagon
spanner ).
2.Screw off the nut connected to stabilizer bar in same
method; screw off the connecting rod.
Installation of connecting rod of stabilizer bar:
