3. Tear down the retainer ring from the drive shaft with the
calipers, and take down the washer-steering knuckle
shaft spline.
4. Tear down the front wheel hub and the steering knuckle
together.
5. Screw off the nuts that connect the constant speed drive
shaft to take down the constant speed drive shaft.
6. Check and repair the constant speed drive shaft
Inject the molybdenum disulphide lithium grease of 100-110
g in the end of ball-cage type universal joint and the end of
axially movable tripod universal joint.
The ball-cage type universal joint and the axially movable
tripod universal joint should swing freely, and no clipping
stagnant is allowed. The dust cover should be prevented from
deformation and every gripping loop shall be clamping tightly.

12. Rivet the main-tooth nut.
10. Mount the flange and dust cover:
(a) Encase the flange and dust cover in the front speed
reducer shell through the clinch of oil seal.
(b) Lock the flange with the special service tool and screw up
the nuts according to the specified torque.
Fastening torque(140-210)Nm
11. Adjust the preload of driving bevel gear bearing
Measure the play preload between the driving bevel gear and
the driven bevel gear with the torque tester.
Preload:(1.8-2.4)Nm
Remark: if the requirement is not satisfied, change the
adjusting washer between the adjusting washer jackets and
bearing 32307, see the disassembly and assembly for front
speed reducer, until the requirement is satisfied.
(a) If the preload is larger than the specified value, change
with a thicker adjusting washer;
(b) If the preload is smaller than the specified value,
change with a thinner adjusting washer.
9. Mount the new driving bevel gear oil seal:
(a) Encase the oil-guard tray.
(b) Press the new oil seal in the speed reducer shell with the
special service tool; the mounted oil seal should be 1.5
mm away from the end face of the housing.
Notice: Coat the lithium base grease evenly on the lips of
oil seal.
