Causes of abnormal noise from the front wheel of Volkswagen new Passat

The following is a description of the recent "reasons for the abnormal noise of the front wheels of Volkswagen's new Passat". When Volkswagen New Passat is driving in slow bumps, the abnormal sound of the automobile chassis is caused by the improper clearance between the differential axle shaft journal and the differential housing, the improper backlash between the axle shaft spline gear and the differential axle shaft keyway, the improper meshing backlash between the axle shaft gear and the planetary gear, the improper meshing backlash between the differential bevel driving gear and the manual gear, and the wear of the thrust washer. When the car is driving, the rear legs are engaged due to improper gear meshing clearance, improper adjustment of preload of differential bearing or both. When disassembling the joint, it is necessary to separate the meshing clearance between the differential wheel and the reduction wheel, the contact line between the pre-tightening wheel and the reduction wheel and the contact line of the reduction wheel. Check where the abnormal noise of the car comes from before repairing it, and then repair it. Million car purchase subsidy
