my baby won't stop moaning

I have a 1999 S500 Base Model that was passed down to me, 69k Miles, Transmissions good, Engine Runs like New. Universal Exhaust tip, that makes her purr.

So 6 months ago she started squeaking on the right suspension. Had it checked out and and was told that it was the joints rubbing each other. Never got that fixed but it went away during the winter Which I find weird. But now recently I've been hearing a weird ka dunk sound in the undercarriage every time she hit a bump or turn. what could be going on?

LOL, it's probably the same issue, but it has gotten worse.

Yeah. Most likely I got a messed up spring and need to get it fixed because she starts to vibrate when I hit about 75MPH on the highway. Which I don't recall that happening 5 years ago when I gunned her past 100...

You should have the self leveling suspension checked could be out of hydraulic fluid

Thanks. Definitely check into it. I'm getting it checked with star. Full 6-point check up (I think that's what's it's called...) this June. keeping it in the garage and driving my W221 for now.
