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.

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.
