What is the purpose of the Audi 80 wheel bearings?

I am having some issues with my Audi 80's wheels and I suspect that it may be related to the wheel bearings. Can someone explain what wheel bearings are and their role in the vehicle? What are some common signs of worn out wheel bearings?

Wheel bearings are essential components that allow the wheels to rotate smoothly on the axles. They help distribute weight and reduce friction, making the ride smoother and safer. Signs of worn out wheel bearings include strange noises, vibrations, and uneven tire wear.

It is important to regularly inspect and maintain your wheel bearings to avoid any potential issues. If you notice any unusual noises or vibrations while driving, it is best to have your wheel bearings checked by a professional. It could save you from more costly repairs in the long run.
