How to Deal with Abnormal Noise from the Rear Axle of a Car?

[LaKayden]

Reasons and solutions for abnormal noise from the rear axle of a car are as follows: 1. Excessive meshing gap: When shifting gears to decelerate or abruptly changing speed, a "click, click" sound appears at the rear of the vehicle. The main causes are usually excessive meshing gaps between the conical drive and driven gears, cylindrical drive and driven gears, planetary gears and half-shaft gears, or between the half-shaft gear keyway and half-shaft spline teeth. Adjusting the gap or replacing related components can resolve the issue; 2. Insufficient meshing gap: When accelerating or releasing the throttle pedal, a continuous "hiss" sound appears at the rear, accompanied by heating, which is mostly caused by insufficient or poor meshing of gears; insufficient lubrication or poor lubrication can also lead to similar phenomena. Replacing the engine oil or adjusting the gap can solve the problem; 3. Noise from the half-shaft and half-shaft sleeve: When the half-shaft or half-shaft sleeve is bent and rubs against each other, an intermittent "grinding, grinding" sound occurs while driving; if the rubbing is severe, it turns into a "thud, thud" impact sound. Replacing related components or visiting a repair shop for servicing is necessary.
