What is the cause of the strange noise in my Audi 80's engine?

My Audi 80 has been making a strange noise from the engine, it's not the typical engine sound. It sounds like a whirring or grinding noise. It only happens when the car is moving, and it gets louder as the speed increases. What could be causing this and how can I fix it?

It's possible that your Audi 80's wheel bearings are worn out, causing the strange noise. This is a common issue in older cars and can be fixed by replacing the bearings.

Another possible cause for the noise could be a worn out CV joint. This can be fixed by replacing the joint or by getting a new axle installed.
