Before you back in to your site, don't forget to remove your anti-sway bar...first of all, with the sharp turns you make when backing up, you can damage your device..and secondly, it will impede the turns you want to make..finally, it often makes a lot of noise when you're trying to back up with it on that makes it sound like there's something wrong...so, first thing, before you start to back up..take off that anti-sway bar.
