The stabilizer is a pretty easy part to service. The struts aren't as easy, unless you have a bit of experience. But if you use a manual and take your time (start on Saturday morning, and give yourself the whole weekend for trial and error), it's perfectly do-able.
I DOUBT the stabilizer is bad - it's just an easy thing to check before you go tearing anything apart.
ALSO - have a look at your exhaust pipe. There's a chance a hanger or heat shield has let go, and the pipe is rubbing when the suspension moves.
There are several of us in Columbus that have done MANY complete suspension overhauls, so we can help out with any problems or questions, if you want to give it a go. Myself, Nadthomas, Soldier989, and JAMallott are all experienced with struts & springs, and we're all in the Columbus area; so we could even stop by and lend a hand if you get in over your head.
