What is the cause of noise in an Audi 80's suspension?

I have noticed a loud creaking and clunking noise whenever I go over bumps in my Audi 80. It has become increasingly annoying and concerning. What could be the issue with my car's suspension?

Based on my experience as a mechanic, the most common cause of noise in Audi 80 suspensions is worn out control arm bushings. These are responsible for absorbing impacts and stabilizing the movement of the wheels. Have them checked and replaced if necessary.
