1.
Inspection should be conducted for the following items to
remove the trouble
(a)
Check the tire abrasion and air inflation situation
Tire inflation pressure:
Front (220
0)kPa
Back (240
0)kPa
(b)
Check the front wheel bearing to see whether it is loose.
(c)
Check the front suspension to see whether it is loose.
(d)
Check the steering driving device to see whether it is
loose, and
(e)
Check the front vibration damper work to see whether it
is loose.
2.
Measure the ground clearance of the chassis.
Chassis ground clearance:
Dr
295
0
+5
mm
SL SK
(255 2)mm
SY
(310 2)mm
SJ
(295 1)mm
If the chassis ground clearance of the vehicle is sub-standard,
push down the body or raise it for a trial adjustment, if fails,
check the spring or suspension element to see whether they are
normal.
Remarks: adjust the chassis ground clearance to a specified
value before checking the Alignment of Front Wheel
parameters.
3.
Mount on the four-wheel locating device.
The mount should be conducted according to the manufacturerís
instructions.
