Need help with shock?

I am fixing to get new shocks for my car because Im gussing mine are shot? They squeak really bad and they take bumps really bad! Would getting new shocks solve this promblem or what do I need to do to solve it? So what kind do I need to get and how much are they going to cost me?

thanks adam

Well one way to check you shocks is the bounce test, or you can look at the shock/modified strut and see if there is dirt collecting on the cylinder. Which is caused by the oil leaking out.
does your car float down the highway like your on a boat if so get new shocks.
When you remove the front struts make sure to have your alignment checked after just in case.
