I just found your email, sorry I dont use Yahoo anymore as I had way too many problems with messages being undeliverable and returned and some people couldnt send me messages as they were never recieved. The email address for you or anyone to use for future referrence is on the main page of my website and is "tripleedgeperformance@comcast.net" . I did send you an reply but please try to send all future emails to the comcast account as that is the best way to contact me. Back to your problem and as I sent in your email, your diff is bad and as a MINIMUM needs replaced as well as the housing and possibly speed sensor. If you look at another thread from SyntheticShield labeled CARNAGE there are some pics of what the diff looks like, though his is an HD model. There is a ring gear inside the transmission and is very suspect to having teeth get damaged when a differential fails and if this is the case it must be replaced or will damage a new differential.
