Grinding rear end - bad differential or other problem?

Hi everyone,

I'm experiencing a nasty sound in the rear of my car when i back up while turning. I've been told that it sounds like the posi unit in my differential is going bad or possibly something else back there. I'd like to know if anyone has any suggestions as to how I can narrow down the problem and if I might be able to fix it myself. I don't have much experience working on cars but since I have SPF 1683 I thought you guys could give me some advice. I also plan to buy a 4 post lift in the next few months so that should be a big help with any work I need to do.

Thanks,
Bryan
