Disassembly of constant-speed drive shaft
assembly
1. Check the front drive shaft assembly
a. Check the inner trumpet connector; it could slide in axial
direction smoothly.
b. Check the universal-joint position; it should be without the
clear clearance in radius direction.
c. Check the inner and outer jacket for damage.
Caution: It should use the pad when clamp the front drive
shaft to avoid the damage of it.
2. Remove the large clip of inner jacket
Caution: Do not damage the inner and outer jacket

7. Remove the outer jacket
Caution: Clean the protective jacket and remove the grease on
the outer trumpet connector. Do not disassemble the outer
trumpet connector.
8. Use the screwdriver and hand hammer to remove
the dustproof cover.
Assembly of constant-speed drive shaft assembly
1. Use the hand hammer and screwdriver to install
the dustproof cover
Caution: The dustproof cover should be replaces when
itisdeformed heavily.
2. Install the large clip of outer jacket, outer jacket
and small clip of outer jacket.
Caution: The outer jacket should be replaced when it is
damaged or aged heavily and warp the end of the shaft with the
plastic band and coat with small grease before insert it.
3. Insert the small clip of inner jacket, inner jacket
and large clip of inner jacket.
Caution: The inner jacket should be replaced when it is
damaged or aged heavily.

Replacement of drive gear oil seal of front reducer assembly
1. Support the front of car; remove the left and right
front wheel and the beam under the reducer.
2. Drain the lubricant oil in the front reducer; remove
the left and right steering knuckle
3. Disconnect the front reducer assembly flange from
the drive shaft and use the jack to remove the front
drive axle
Caution: Make the assembly mark on the reducer and
drive shaft before separate them.
4. Remove the front differential assembly
(Caution: Drain the oil in front differential before the
disassembly)

5. Remove the drive gear flange and dustproof cover
assembly
a. Use the hand hammer and chisel to loose the riveted part on
nut.
b. Use the special tools to clamp the drive gear flangeandremove
the drive gear nut.
c. Use the cooper bar to knock down the drive gear flange and
dustproof cover assembly.
6. Remove the drive gear oil seal
Use the special tools to remove the oil seal; do not
damage the inner wall of reducer housing.
7. Install the new drive gear oil seal
a. Use the special tools to knock into the new oil seal.
b. The top of the oil seal is level to the top of reducer housing.
Caution: Coat the oil seal lip with the lithium base grease and
the oil seal should be in correct position.

8Install the drive gear flange and dustproof cover
assembly
a. Match the drive gear flange and dustproof cover assembly on
the front drive gear.
b. Coat the new nut with the lithium base grease.
c. Use the special tools to clamp the flange and tighten the nut
to the specified torque.
Tighten torque:140-160N.m
a. Use the torque meter to measure the pre-applied load of the
gap between the drive bevel gear and driven bevel gear.
pre-applied load: 1.2-1.7N.m
b. Is should be replaced by the thicker washer if the pre-ap
plied load is more than specified value
(The step of thickness of washer is 0.03mm)
c. Is should be replaced by the thinner washer if the pre-applied
load is less than specified value. Repeat the previous
operation until meet the requirement.
Caution: Do not reduce the load by loosing the nut.
10. Check the axial and radial run-out tolerance
offlange.
a. Use the dial indicator to measure the axial runout of flange.
Max. axial runout: 0.1mm
b. The max. radial run-out tolerance is 0.1mm
It should check the bearing if the radial run-out tolerance is large.

20. Check the engaging mark of drive and driven
bevel gear.
(Refer to “Assembly of Front Reducer Assembly”)
21. Measure the pre-applied load of drive bevel gear
bearing.
Use the torque measuring meter to measure the preapplied
load on the gap between the drive and drivenbevel gear.
Range of pre-applied load: 1.2-1.7N.m
22. Measure the total pre-applied load of drive bevel
gear.
23 Remove the drive gear flange and dustproof cover
assembly.
a. Use the hand hammer and chisel to loose the riveted part of
drive gear nut.
b. Use the special tools to clamp the drive gear flange and
remove the drive gear nut.
c. Use the brass rod to knock down the drive gear flange and
dustproof cover assembly.

1.Rotate the driven bevel gear, check the runout of
driven bevel gear.
Max. Runout: 0.07mm
Assembly of front reducer assembly
1.Install the adjusting washer in the drive bevel gear,
install the big bearing inner race of drive bevel gear
by press.
2. Clean the front reducer housing, install the outer
race of big and small bearing on the reducer housing
by press..
3. Install the drive bevel gear into the front reducer
housing, then install the washer, spacer and small
bearing inner race.
4.Use the special tools to install the drive bevel gear
oil seal.
Caution: It should coat the lip with the oil seal
lithium base grease before install it and the rear
surface of rear oil seal should flush with the top of
front reducer housing after knocked in.
5. Install the drive gear flange and dustproof cover
assembly.
(Refer to “Replacement of Drive Bevel Gear Oil Seal”)
6.Use the special tools to tighten the drive gear nut
to the specified torque; the nut should be precoated
with the lithium base grease.
