Caution: It should screw on all bolts before tighten
them, then tighten them in diagonal direction.
Check the hanger plank for levelness after tightened
the bolt to the specified torque. Remove the hanger
plank and reinstall it if is not planished.
8. Install the vent tube connector assembly; connect
all ports to front drive axle.

6. Use the wrench to screw off the bolt on the vent tube
bracket, which is used to fix the vent tube connector.
7. Disconnect the connection between the front drive
shaft assembly and steering knuckle front hub
assembly.
a. Screw off the connecting bolt which is used to fix the front
hub cover; remove the front hub cover.
b. Use the circlip pliers to remove the circlip from the front drive
shaft and remove the adjusting washer.
c. Remove the steering knuckle of both sides and separate it
form the front drive shaft assembly.
1. Support the front of the car; remove two front
wheels and the beam under the front reducer
assembly.
2. Drain the lubrication oil in the front reducer
assembly.
3. Remove the flange of front reducer assembly from
the drive shaft
Caution: Make the assembly mark on the flange of
front reducer assembly and drive shaft before discon-
nect them.
4. Disconnect the connector of power wire of electric
clutch
5. Disconnect three rubber connectors on the front
drive axle vent tube connector assembly.

9. Remove the lifting bolt of front drive axle hanger
plank and carriage.
10. Remove the front drive axle assembly
Caution: Do not damage the drive shaft and front drive
shaft jacket
11. Remove the front drive shaft assembly of both sides
from the front drive axle assembly.
12. Use the wrench to remove the bolt and nut which is
used to fix the front reducer housing.
13. Remove the clump weight assembly and clump

Replacement of major semiaxle oil seal
1. Make the electric clutch is in the 4WD status,
them stop the engine and remove the front drive
axle assembly (see the disassembly of front reducer
assembly)
2. Use the wrench to screw off the bolt which fix the
front axle vent tube connectorassemblyonventtubeb

3. Disconnect the connector between vent tube of
electric clutch housing and front drive axle vent tube
connector assembly
4. Disconnect the connector between the vent tubes
on the electric clutch and vent tube connector
assembly.
5. Remove the bolt which is used to fix the electric
clutch housing and front axle tube flange; use the
brass bar to open the electric clutch housing and take
out the mechanical wheel of separator.
Caution: The lubrication oil will flow out when sepa-
rate the electric clutch housing from the front axle
flange. It should use the container to hold it.

9. Remove the sealant on the matching surface
between the flange and electric clutch housing by
knife.
Caution: Do not scratch the matching surface.
10. Use the special tools to knock the new seal in the
oil seal position in flange.
Caution: Before install the new oil seal, it should
coat the lip with thin lithium base grease, and the oil
seal should be in alignment position.
11. Insert the spline of small end of major semiaxle
in the spline of front reducer half axle gear slightly,
then use the brass bar and hand hammer to knock it
in.
Caution: When knock in the major semiaxle, must
not damage the inside needle bearing of large end
spline of major semiaxle.
12. Use the circlip pliers to install the circlip in the
flange and clamp the bearing outer race.
Caution: The circlip should be replaced if it has
serious deformation.
13. Use the clean cloth to wipe the matching surface
of flange and electric clutch housing respectively.

14. Align the spline of mechanical wheel of separator
with the spline in front drive shaft and separator
shift fork sleeve, and install it in the front drive
shaft and separator shift fork sleeve.
15. Coat the flange matching surface with the 1596
silicon rubber plane sealant uniformly and level it by
plate.
Caution: Ensure the continuity of sealant and avoid
the sealant enter into the screw hole.
16. Align the shift fork bush with the spline on the
major semiaxle to make the mechanical wheel of
separator enters into the major semiaxle, then use
the bolt to connect the electric clutch housing and
front axle pipe flange and tighten it to the specified
torque. In which the bolt should be precoated with
the screw locking agent (drip one or two drops on the
middle of screw).
specified torque : 90-110Nm
Caution: Prevent the foreign material from entering into the
front drive axle during assembly.
17. Use the wrench to tighten the bolt of vent tube
bracket to tightening torque.
Tightening force: 23-26Nm
18. Screw off the oil filling plug on the electric clutch
housing, remove the washer and fill it with the gear
lubrication oil until flush with the bottom of oil
filling port.
Number of lubrication oil: GL-5
19. Place the washer of oil filling plug, tighten the oil
filling plug to specified torque.
Specified torque: 140-150N.m

20. Connect the vent tube on the electric clutch
housing to the front axle vent tube connector
assembly.
21. Connect the electric clutch vent tube to the
