A high-speed runout two cases, G35 Adjustable Coilovers one with increased speed, runout gradually strong; the second is at a higher speed appear runout. And cause the steering wheel shake, first set up the drive axle, front wheel plus safety plug block, start the engine and gradually shift into high gear, the speed of the drive wheels to achieve the shimmy. If at this time the body and the steering wheel shakes, for the transmission caused by runout. Because the front wheel axle in a quiescent state, if runout try to reach the final speed, the car does not appear jitter, the runout of the reasons there is a fault line before the bridge part of the car;

Second, check the front wheel angle and the toe meets the requirements, such as misalignment should be adjusted;

Third, set up a test before the bridge turn the wheels, check the wheel static balance and tire deformation is too large. If necessary, change the wheels comparison test;

Fourth, check the front axle, the frame is deformed, check whether the shaft is bent driveshaft balancing conditions should be doing;

Fifth, check the front leaf spring stiffness, performance and spring shock absorber bracket loose rivets, the performance does not comply should be replaced.
