Steering Wheel Free Play Inspection
1. Stop vehicle and position front wheels straight ahead.
2. Slightly turn the steering wheel left and right, and check
rotation angle of steering wheel when the wheels start to
rotate.
Standard value of free play (rotation angle): a ≤ 15°.
3. If measured value exceeds standard value, check the steering system.
Steering Wheel Centering/Returnability Inspection
Steering wheel centering/returnability inspection should be performed during road test.
1. Perform the slow turn and sharp turn test.
Check for deviation of steering wheel steering force required during left/right turn and centering/
returnability.
2. When vehicle speed is between 20 and 30 km/h, turn the
steering wheel either to left or right by 90° and keep it for
1 to 2 seconds, and then release the steering wheel. If
steering wheel turns back more than 70°, it is determined
that steering wheel centering/returnability is in good
condition.
3. If steering wheel returning angle is not as specified, check the tire pressure, steering system and
suspension system.
