+1 Go for the True Trac. I bought one from Ron a while back and don't regret it.
Hey Ron, if I get gear whine only when I am decelerating does that mean the pinion nut needs to be tightened a bit more? It isn't a bad whine, and a local differential guy said that's all it will need. Just want to make sure so I don't have to pull it out and put in another crush sleeve.
