Car still makes loud noise when going over bumps

My car was making loud noise open traveling over bumps. I replaced both rear shocks and it got better but there still is a loud noise coming from the passenger rear side. Nothing is hitting the ground although it sounds like it. It takes two people pushing down on the car on that side to make the noise and you can hear it pretty loudly. And if you do the other side the same way it won't make the noise. Idk what else to look at. Any ideas

I'll also add it doesn't make noise by myself unless going over a pretty decent bump. But it really made bad noise with 2 300lb guys in the car. I know that's a lot of weight but it still shouldn't make that sound with them over every bump

Check the rear sway bar links. As well as to look at the control arms to see if any bushings are gone

Get under there and use a ruber mallet and hit everything you can that wont break. I found one of my shock bolts were looks. It also could be your exhaust moving and hitting something.

I understand the rattling but the car makes a violent sound as if the car is hitting the ground with people in the car. And when pushed down on the side of the car where it's making the noise it makes the same clunking noise and nothing is hitting the ground. I'm thinking maybe it could be the upper control arm bushing?

Could be where your exhaust goes over the axel. Its very close to where the body of the car is and if it's lowered its even closer.

I checked and when the car is getting pushed down on the exhaust will touch the axle but only on the bad side. Could that be from a bad control arm bushing because the car will still squeak from that side over small bumps with me in the car and with two guys the exhaust was hitting the axle making the clunking noise.

I had the same issue with my 2000 GT before storing it. I replaced the control arm bushings on both sides as well as replaced both rear shocks/struts. There isn't a problem anymore. Now just trying to get my car to start after 18 months in storage.
