if this is about your W124 as in your signature then I can tell you what did that on my W124 E300D

my problem was a combination of worn struts and worn ball joints, the worn ball joints made the car sit lower and the struts didnt do anything in terms of keeping the car taut.

so my car would rub tires in the wheel well. Replacement of the said parts resolved all issues.

the bad part in your car is that you cannot change the ball joints by themselves like I could on my diesel one. Your car has ball joints integrated into the control arms, so you need to buy new complete arms - pricey.

You can test the joints by raising a wheel with the jack under the control arm so the spring doesnt load the joint, then use a pry bar or 2x4 or something similar to lift up the wheel. If you see it move or clunk, you just found your issue. If the joints are ok then inspect the strut bumpers, the prevent the strut bottoming out, you will need to look behind the black rubber accordion which covers the strut piston.
