The right rear of Volkswagen's new Jetta Expressway is abnormal, and the right rear wheel of the new Jetta is bumpy.

Abnormal sound at the right rear of Volkswagen New Jetta Expressway First, check whether the right rear wheel tire screw is tightened to eliminate abnormal sound symptoms. When the wheel hub screw is loose, lightly step on the brake when going downhill, and the wheel will make a slight knocking sound. If the rear wheel screws are loose, the noise of the wheels will be amplified through the trunk, which may be mistaken for something in the trunk. When the wheel hub screw is loose seriously, the wheels will swing when walking, and obvious clicking sound will be heard at low speed. At this point, stop immediately to check the hub screw. If the tire noise is rhythmic and high in frequency when the vehicle speed is fast, judge the reason according to the sound: if it is low "snapping" sound, it is mostly tire tread deformation, bulging, serious wear or insufficient air pressure; If it is a "click" sound, it may be that the tread is mixed with pebbles; If the tires whir and the car body shakes obviously or even deviates, it goes without saying that the tires must have a flat tire. Get off and change the tire. If there is a metal collision sound inside the tire during driving, it may be caused by the damage of shock absorber and bearing, and the owner should go to a professional garage or 4S shop for repair.
