What causes the rear axle noise in Pajero V73?

[LaLeilani]

Pajero V73 rear axle noise causes are detailed as follows: Improper tooth side clearance: Noise from improper tooth side clearance. When the preload of the main reducer bearings is normal, a metal impact sound occurs at the rear axle shortly after starting the car or during gear shifting. As the speed stabilizes, the impact sound turns into continuous noise. When the throttle changes abruptly, an irregular noise appears at the rear axle, which is generally caused by excessive tooth side clearance. Bearing wear: While driving, if the noise increases with higher speed and decreases or disappears when coasting, it is usually due to bearing wear or abnormal gear clearance. If the noise occurs when abruptly changing speed or going uphill, it indicates excessive gear meshing clearance.
