What Causes the Rear Axle Noise in Changan Yuexiang?

[DelLucas]

Changan Yuexiang rear axle noise can be caused by excessive meshing clearance, insufficient meshing clearance, noise from the axle shaft and axle sleeve, etc. Excessive meshing clearance: When shifting gears to decelerate or abruptly changing speed, abnormal noise occurs at the rear of the vehicle. The main causes are excessive meshing clearance between the conical driving and driven gears, cylindrical driving gear, planetary gears and axle shaft gears, or between the axle shaft gear keyway and axle shaft spline teeth. Adjusting the clearance or replacing related components can resolve the issue. Insufficient meshing clearance: When accelerating or releasing the throttle pedal, abnormal noise occurs at the rear of the vehicle, often accompanied by overheating. This is usually caused by insufficient meshing clearance or poor meshing between gears. However, insufficient or poor lubrication can also produce similar symptoms. Replacing the oil or adjusting the clearance can fix the problem. Axle shaft and axle sleeve noise: If the axle shaft or axle sleeve is bent and rubs against each other, abnormal noise will occur while driving. Replacing the affected parts or visiting a repair shop is necessary.
