I got into an accident 2 weeks ago , got my hotchkis LCA since the OEM ones were dent and cracked . Set up my alignment and camber blablala. Now it has a very bad squeak , not that this happened after i install my hotchkis's , since the accident it was this bad but the first day i installed the LCA (before alignment and camber adjustment) it wasnt this bad . Bushings are all fine since they're new . Could this be my springs or shocks ? Currently using h&r race spring .

 

Ball joints.

 

They have ball joints for rear?

 

Just to be sure... you are talking about a squeak in the rear suspension, right?

BTW, do you have poly bushings?

 

I use the ones that came with the lca (hotchkis). Yes in the rear suspension

 

What about poly bushings? A while back I had a most annoying sweaking the rear and turned out to be dry poly bushings on my sway bar...

 

Guess I should read the whole post I'd agree with the other that its most likely bushings since its in the rear. I haven't heard of springs or shocks doing this but hey I could be wrong. You said you were in an accident so unfortunately it could be any number of things..
