Wheel bearing noise humming, grinding, o r growling is a well-known issue for Santro, especially older models.

Common Reasons

Low-quality replacement bearings
Cheap bearings fail quickly—common in local markets.

Rough road conditions
Potholes and speed breakers damage bearings over time.

Overloaded vehicle
Excess weight puts extra stress on the bearings.

Lack of lubrication
Older bearings dry out and start grinding.

Misalignment o r bent hub
A bent wheel hub causes uneven rotation and bearing wear.

Signs Your Bearing Is Failing

Humming noise that increases with speed

Noise becomes louder when turning

Slight vibration in the steering wheel

Tyre feels loose when shaken from the side

What to Do

Replace with high-quality original o r Korean bearings.

Ensure proper installation with correct tools.

Check wheel hub and axle for damage before fitting the new bearing.

Avoid overloading the car on rough roads.
