A high-speed runout, there are two cases, one with increased speed, gradually strong runout; second, appeared at a high speed oscillating. And jitter caused by the steering wheel, set up the first drive axle, front wheel increases security plug block, start the engine and gradually change into high gear, the drive wheels to shimmy speed. If the body and steering wheel are now shakes, was caused by runout transmission. Because at this front-wheel front axle in a quiescent state, if the runout speed up the final test, the car does not appear jitter, the runout of the car before the bridge part of the system because there is a fault;
Second, check the front wheel toe angle and the positioning of compliance requirements, such as inaccurate should be adjusted;
Third, set up test before the bridge turn the wheel, check the wheel balance and static deformation of the tire is too large. Necessary, change wheels comparison test;
Fourth, check the front axle, the frame is deformed, check the shaft is bent, should be made conditional shaft balancing;
5, check the stiffness of the front leaf spring, shock absorber and spring bracket the performance of loose rivets, etc., do not meet the performance should be replaced.
