When im driving at lower speeds, especially when going over small bumps when pulling into a driveway or something like that, i keep hearing a loud clunking noise like something is broke. Doesnt do this at highway speeds over bumps just slow speeds. Also, when in park if i rev it up it rumbles and clunks when RPM's fall, and when changing gears from park to reverse. Im completely lost on where to start looking. Also, no trouble codes, and the noise sounds like its coming from the right rear-or trunk area. Help please

 

Suspension noises can come from a lot of places.

I would watch the ericthecarguy video on finding suspension noises. Search for v=scFbb43fwqk on YouTube for the video.

 

that was my first thought but when it began making noises from park to reverse and when idling back down it made me question that. can it be something broke inside the muffler or exhaust related? muffler is solid-no rust.

 

All of that stuff is covered in that video. You will just have to go through the possible sources of noise until you find something wrong.
