What is the cause of the squeaky noise in my 1992 Audi 80 steering wheel?

I have recently noticed a high-pitched squeaky noise coming from my Audi 80 steering wheel whenever I turn it. It seems to be occurring more frequently and is becoming quite annoying. I am wondering what could be the cause of this and how I can fix it.

The most likely cause of the squeaky noise in your steering wheel is worn out or damaged steering wheel bearings. These bearings are responsible for smooth and quiet operation of the steering wheel, and when they wear out or get damaged, they can produce a squeaky noise. You should have your steering wheel bearings checked by a mechanic and replaced if necessary.

Another possible cause of the squeaky noise could be a loose or worn out belt in the steering system. As the belt wears out, it can develop cracks and slips, which can cause a squeaky sound. Have your steering belt inspected and replaced if necessary to eliminate the noise.

If neither the bearings nor the belt seem to be causing the noise, it is possible that there is a problem with the power steering fluid. Low or contaminated fluid can cause the steering system to make strange noises. Make sure to check the fluid levels and quality, and top up or replace if needed.
