Very bad Knocking/clunking sounds from rear end.

[peterpeter]

So, my car drives pretty bad right now. The bad part is when I accelerate over bumps, the rear end has a terrible bouncing/knocking/clunking type of noise, and it sounds like something is loose and is jumping around. I don't know what it is, but the best way to explain it is that it feels like the back tire is jumping up and down rapidly. I have to let off of the gas because it sounds like something's going to break. Also, over bumps and potholes the whole car rattles and makes noises, so that may be the shocks? Any help is appreciated, I just hate driving it right now because of this issue. I could try to get a video of the sound also.

Good place to start. I would also look at your battery to see that it isn't bouncing on big bumps like mine was.

Could also be rear subframe bushings.

Hopefully, it's just the shock mounts. Easy fix.

my car does something like this but only when i beat on it from a dig but it only happens on the passenger side. i have condor subframe bushings and on the rear control arms and on the diff, my rear stock mounts are good. only thing i can think of is that i don't have the spring pad on the bottom of the rear spring. this started happening after i lowered my car with low tec springs.

Alright, so I did forget to mention that the whole car makes clunky noises over all bumps, so should I just start by replacing all the shocks? And I just looked up info about the shock mounts, so I'll check those on my car tomorrow.

Also, I'm very new to this forum, is there a good way to know when people are replying to threads that I start? I completely forgot I even posted this.. I know I can do email notifications but I rarely check that anyways.

In the settings change it to instant notification then set up that account to your phone, almost like texting haha

Edit: make a brand new email for forum use! My forum email has like 9k emails since April or something!
