EXTREMELY Bumpy Ride! (with Occasional Thuds)

Just bought used 2005 Cobalt LS.

It drives fine but when it goes over potholes, the car really feels the hole (along with a loud noise). I drove over it with a newer car and the same bumps barely feel like anything.

Is this normal for old cobalts?

Potholes have always made loud noises for me when I went over them. I always assumed that was normal for any car. Normally I just try to avoid them though.

Do the bump test. Push the car down at each of the four corners and see how many times it bounds/rebounds. It should stabilize almost immediately. If it sways like a dingy in a tropical storm, you have a problem.

Common problem. Now's your chance to upgrade to FE5 hardware if you haven't already.

The rear springs probably just have the top or bottom coil broke, we've all had this problem and you can't even tell until you actually look.

Also, check your control arm bushings. Specifically the rear bushing that's like a hockey puck, I can promise you unless they were just done that they need to be.

On my cobalt I replaced sway bar links, sway bar bushings, and control arm bushings. 8 months later I needed to replace one of the sway bar links, the sway bar bushings, and the control arm bushings were bad again. Needless to say I bought a new car because I wasn't doing that every 8 months.

My springs never broke haha and I have yet to have a problem with the bushings... I don't know if they were ever changed but they haven't been in the 20k miles I've owned it
