I have a 2009 Pontiac GT G5.
(Backstory) When I bought it off this dude the rear driver side wheel was stanced because of an accident the previous owner was in. The dealer fixed the problem with a part from a junkyard. But when he did that, it messed up my alignment, which I got fixed. It was driving perfectly for a while but it is now drifting or spinning out from under me when I am turning or bearing left, it feels like it could spin out if I hit the right bump. But if I am on a smooth road, everything is fine.
When I look at my car driving away I see a large spring hanging down on the radar passenger side, but that only shows when I’m driving, not when it’s in park.
For reference I have a torsion suspension system in the rear.
I also have an issue where my break pedal will groan and almost push back on my foot. Maybe this has something to do with the suspension as well? This doesn’t affect the quality of breaking.
When I have to break quickly the rear passenger side wheel will make a very loud noise, I’ve been told it could just be the abs breaks trying to work.
When I look under the car I don’t see any visible/obvious damage. It’s a great little car on smooth roads but struggles a lot on bumpy roads or roads that have those breaks in them for rainwater or repairs.
I have the abs light on, the traction light on, and the check engine light on (which is just an oxygen sensor),
Does anyone know what could be wrong with my car? I am a college student with barely any money so I am trying to figure this out for myself but I haven’t been too successful. Any help would be appreciated.
