The 12-bolt in my truck has well over 300,000 miles on it and is as tight as can be. This truck has seen a hard life--it was a fireman's truck for much of it's life. I had a diff carrier bearing go out in another 12-bolt once, but that's the only failure of a 12-bolt in a very long family history of them.
