Toy,
Mine still does it every once in a while too.
I have found that both my rear tires need to have the SAME amount of air in them in order for the locker bang not to happen as often. Also I keep a close eye on my diff oil. Please note that my LockRight has been in my truck since 1994 and is still going strong. I would not worry too much about it. Great off-road. Do a search on this board for LOCKER BANG from a couple of years ago.
