I second hd95. Even if one stud gets corroded you can have big troubles. When I removed mine, I experienced the one on the very bottom being corroded and it took me several weeks to get it apart, I almost gave up. I was finally able to get two thin paint scrappers in on the top side and eventually mine popped. My WJ is super clean with almost 0-rust. So with the amount of salt you guys use and how bad your winters are there, you could have a real problem for sure. Good luck.
