I plant maintenance Jinbei 6480 bus in the process and found that many new cars there is a serious automatic deviation phenomenon. A company a new car, driving, as long as the driver’s hand to leave the steering wheel, immediately left deviation automatically when the road is wide or even automatically turn around. A variety of instruments used to detect, correct, but failed to troubleshoot.

Automatic correction after the deviation has been reduced, but still not completely eliminated. Further examination revealed that the steering wheel in the middle position, the two front wheels are not positive (from the body centerline distance range), the left wheel is too large, the right wheel is small. Then tie rod will be left
