OK, I tried to get some input in the General Discussion Section....

Plan is for Sherman to have a Detroit in the rear.

Up front I have to go with L/S because for now Sherman may have to be used for a back up commute mobile, so will need some highway manners.

So......what are the +s & -s to Danas and Auburns? Is one better than the other?? (One is definitely more expensive than the other.) But is the money worth it????

I just went through this same situation, except it was between an Auburn and a Detroit Truetrac L/S. The main focus I had was on durability. The Auburn uses cone clutches much like the center diff of a Q-Trac does. The Truetrac uses helical gears to achieve it's limiting capabilities. Any sort of clutch is eventually going to wear out and therefore become useless, whereas the helical gears are good for the serviceable life of the rest of the diff. Also, with a clutch based L/S, you need to use a friction modifier additive to your gear lube. With the Truetrac you don't. Now as for the Dana's, the traclock is a pretty weak unit. It likes to wear out aweful fast when it comes to clutches, and you can't adjust the preload to get more torque biasing out of it. The Powerlok from Dana, you can, and it's a beefier unit. It's a good unit, but for the money you could spend on one, you could spend a little more and step up in the world. Can you tell which L/S I decided to buy?
You guessed it, a Detroit Truetrac. I asked everyones opinion on the matter and the concensus was that it's the best limited slip you can get for a 4x4, and it works especially good in the front axle.

Glean what you want from that babble...I got a little long winded and started to ramble :D :D

i've had good luck with the dana trac loc. I had one in my fd44 w/37's and it never let me down and it works real good on snow and mud but the not the ticket for rockcrawlin. I helped a guy fix a broken trac lock on a upper helldorado @ moab last month but he had a big blazer and 39" krawlers.

I would go with a detroit electrac for the front or a detroit tru trac over any other l/s's

The tru-trac actually usses worm gears. And doesnt provide a 100% lockup. But it is one of the stronger LSD's. The power-loc is better for harder stuff, as they can provide a 100% lockup with the right setup.

Hmm...what does a helix look like? A worm gear!

n. pl. he·lix·es or hel·i·ces (hl-sz, hl-)

1. Mathematics. A three-dimensional curve that lies on a cylinder or cone, so that its angle to a plane perpendicular to the axis is constant.

A "helical gear" pretty much means any gear...

worm gear
n.

1. A gear consisting of a spirally threaded shaft and a wheel with marginal teeth that mesh into it.
2. The toothed wheel of this gear; a worm wheel.

Sorry to get technical...

ive also got a truetrac in my frontend,and ill agree 100% that as limited slips go,it is the one to use.

rustyjeep covered it pretty well.onlything ill add is that with some sneaky use of pulsing the brake pedal,mine will still get power to the wheel even if the other side is dangling in the air.

defiantely a great unit for a front axle.

Yep, sounds like it is going to be my choice.

Now, who has the best prices on gears and diff's???????

I have heard nothing but good review's on the true-trac in the front. I was going to go with the true-trac but didn't have the money at the time so I traded a dana 44 straight across for a E-Z locker and I didn't have to set up my gears again. I have heard many people say that a detroit in the rear, true-trac up front is a great setup. If between the 2 you mentioned I would go with a Auburn, I will last a little bit longer.
