New rear struts, Squeking noise Options

[Blackdolla]

I got hit in on the rear side, and had to get new stuts, control arms and some other stuff. Ever since I got the new sruts I've been hearind this dull squeking noise coming from the rear. I suspect that it's the struts cause I only hear it when I roll over a bump and car goes up and down. Could my stuts have been installed wrong or be loose?(i didn't do it myself) I think it might also be that my hatch has been knocked loose because of the accident, but I'm leaning towards the struts. Can anyone help?
Thanks

If you had a good bit of the suspension replaced (control arms, end links, etc.) one thing that might be squeaking is the bushings. You might want to make sure that the rear sway bar bushings have good lubrication, the end links are in good shape, that kind of thing. Also, while you are under there, check for rubbing issues... if you got hit, there might be something crooked in there that is binding up and rubbing against something. You might see tell-tale marks if you climb under there.

good luck
