			Think mine is ailing, what do you guys think if I have to replace it, Detroit True-trac or Auburn pro-series (going in a moser 12 bolt)

			i heard excellent things about the true-trac.... no personal experience though. i would run the true trac personally if i had a 12 bolt

			I was into getting a true-trac for a while, but I opted for an Eaton in my twelve bolt.  The Eaton works just fine excet that you have to replace the clutches.  The true-trac is maintenance free since it is worm gear driven and has no consumable parts.  Both units do exactly the same thing though.

			Because I have an Eaton now and it will have to be rebuilt. And I am not particularly happy with it's durability or performance, but that is an option also. Also the Eaton and the true trac work in opposite ways. The True-trac stays locked until it needs to release a wheel in the turn, where the Eaton is a standard limited slip Diff.

 Well, if you decide to dump the eaton and it's a 33 spline 4 series unit let me know

			Eaton is definately a good choice, go auburn pro-series if you wanna save a few bucks.

			Auburn= junk 
Eaton= Better 
Tru Trac= best for the street in a 12 bolt.

			i have always had good luck with auburn diffs. they handle side loading and handling applications better than most and they easy to freshen/rebuil when the friction materials get worn.

 What I meant was that both are limited slip units that transmit equal power to the drive wheels
