WHEEL FREE PLAY CHECK
1.With engine running (hydraulic operation), set front wheels
straight ahead.
2.Measure the play on steering wheel circumference be fore
wheels start to move when slightly moving steering wheel
in both directions.
Limit: 30 mm (1.2 in.)
3.When play exceeds the limit, check for play on steering
shaft connection and steering linkage. Correct or replace.
4.If the free play still exceeds the limit value, set steering
wheel straight ahead with engine stopped. Load
5
(1 lb.) towards steering wheel circumference and
check play.
Standard value (steering wheel play with engine
stopped): 15 mm
in.) or less
If the play exceeds the standard value, remove stee ring
. .gear box and check total pinion torque.
STEERING ANGLE CHECK
37200110131
1.Locate front wheels on turning and measure’
steering angle.
Standard
Inside wheel: FWD AWD
Outside wheel: FWD AWD
2. the angle is not within the standard value, the’
toe is probably incorrect. Adjust toe (Refer to GRO UP’
On-vehicle Service.) and recheck steering angle.
END BALL JOINT BREAKAWAY TORQUE
1. Disconnect tie rod and knuckle with special tool .
1.Be sure to tie the cord of the special tool to a
nearby part.
2. Loosen the nut but do not remove it.
2. jdint stud several times and install nut on stud.
Measure ball joint breakaway torque with special to ols.
Standard value:
Nm (4-22
When the measured value exceeds the standard value ,
replace the tie rod end.
4. When the measured value is lower than the standa rd
value, check that the ball joint turns smoothly wit hout
excessive play. If so, it is possible to use that b all joint.
