|
(1) |
Steering wheel free play |
Move the steering wheel vertically toward the shaft to ascertain if there is play in the direction.
Maximum permissible play:
0.5 mm (0.020 in)
3. Drive the vehicle and check the following items during operation.
(1) Steering force:
The effort required for steering should be smooth and even at all points, and should not vary.
(2) Pulled to one side:
Steering wheel should not be pulled to either side while driving on a level surface.
(3) Wheel runout:
Steering wheel should not show any sign of runout.
