Why does the new Alto make a buzzing noise while driving?

[GabrielaAnn]

New Alto makes a buzzing noise while driving for the following reasons: Wheel bearing damage: After the vehicle has been driven for a long time, the bearings will inevitably accumulate dust and other dirt. Rainwater or dirty water from the roadside can also seep into the bearings, diluting the grease and reducing the lubrication effect. Without the buffer of grease between the steel rings and balls, wear and tear naturally increase, leading to noise. The "buzzing" sound gradually starts to appear. Introduction to the new Alto: The first impression of the new Alto is its rounded and smooth contours. Compared to the older model, the biggest change is the departure from the flat and plain exterior. The unique design of the front face, in particular, is cute and stylish, a stark contrast to the old-fashioned design of the previous model. Additionally, the new Alto features circular headlights, which are also vastly different from the design of the older model.
