Not much info, maybe CV joint? Or suspension mounts gone. Did you buy recently? Did you hit a pothole?

TBH, just take to your local mechanic and have them take a look. I'm sure it will be obvious

Lift Your car with a jack and check your rear subframe and arms. Push and pull all the arms to see if they move or not.
I recently had a similar issue, the part of the subframe to which an arm is connected literally broke off, and the arm was just staying suspended in the air, moving freely, hitting some parts when braking, hence the clunking noise.
the rear subframe corrosion seems to be a somewhat typical problem in this model and the c class..

Let just hope it won’t be this problem
