1. Turn the steering wheel fast to the right and left and

turn it slowly as the same way.

turning to right and the one to the left are same.

3. Turn the steering wheel to 90

about 1–2 seconds

and loosen the steering wheel during the low speed
driving.

4. If the steering wheel restores above 70%, the steer-

ing wheel restoration is OK.

5. If the restoration is poor, check the tire pressure,

steering gear preload, and steering gear operation.
And repair the fault.

CHECK THE TURNING RESISTANCE
OF THE TIE ROD END OR TIE ROD

1. Turn the ball joint of the tie rod end or the tie rod about

10 times.

2. Use a spring balance to check the turning resistance

of each ball joint.
