Not especially easy. If it was bouncing then the rollers in the regulator are probaly shot. You'll be pulling the door panel and waterdam and the glass channel run. Hopefully you can get to the fasteners that will allow you to remove the window. After that you just need to get the regulator attachment points loose. I tried to post some images that would help you but something is preventing me from doing that.
