Locker, open or limited
I've got an 06 base model (ST). I've gotten stuck 3-4 times and each time only the left rear wheel is spinning. Doesn't this mean I have an open differential? I'm going ti change the gears out to 3.42, and I'm thinking about upgrading to a locker if mine is just an open differential. It sure doesn't act like a limited slip.
Also, anyone know of a trust -worthy shop to change out the gears??

It depends on how you got stuck. The Dodge uses a modern version of the Gleason worm drive - no clutch packs. Since there's no clutch packs, it usually last longer. A Detroit Gear (Eaton) TruTrak and the Torsion T1 and T2 are the same thing
During normal operation most of the torque goes to the wheel with the most treaction; just like any other LSD. But if one wheel has absolutly zero traction - ice, lifted off the ground, broken axle - then all power goes to that wheel, and the truck doesn't move. A slight bit of brake pressure will usually resolve that, and return some torque to the other wheel.

if you dont mind the feeling of a ton of gear back lash, then put in a auto-locker, I cant imagine one of these heavy trucks with only 2wd on anything less then pavement. The factory diff isn't very impressive at all in off road conditions so I wouldnt waste my money on one if you need good slow speed traction.

If not, it's not difficult to add it - but not very cheap. Dodge uses a modified Gleason worm gear for it's LSD. No clutch packs to wear. Additive not needed. It has very smooth operation, and very quiet. Unless you're drag racing, it's a better option than a locker.
I have a similar diff in my race car. Go to Eaton Gear's web site, and read about their TruTrak diff.

I hate to tell you this but your 2wd 6 speed truck is never going to do well in any off road situation.
I had a 07 2wd 6 speed and I had to get rid of it of that very reason. The way the clutch puts the power to the ground you just cant be gentle enough to get going even on wet grass, combine that with the weight on the front end and it won't matter if both rears spin or not. My 2wd had limited slip, it won't help.

Thanks for the info. I'm fixing to buy the truck off. And I really don't want to have to start making payments all over again I can get a used limited slip put in the truck for about 600. I think I will at least try that route rather than looking for new truck just yet.
I tried the 1 wheel on the dirt road and the left will on the asphalt trick. The right wheel started spinning and the left wheel did not spin at all. That just proves that it is not a limited slip correct?

Unfortunatly, no. The stock LSD is a modified gleason worm gear. If you raise on wheel off the ground - no traction at all - that wheel will spin and the wheel on the pavement will just sit there. If you apply a little bit of brake pedal, the torque will shift to the other side.
The worm gear is dependent on adjustment and wear. If it has not been assembled correctly from the beginning and it has some wear on it, it may not operate correctly.
Jack both rear tires off the ground. Remove the parking brake, and put the trans in neutral. Turn one tire foreward. If the truck has a functional LSD, the other tire will turn in the same direction.

I'll try that tonight. Thanks for the suggestion.

Positraction is the GM name for heir particular brand of clutch type LSD - Limited Slip Differential. At no point is the Air Locker a limited slip differential.
The Air Locker actually locks the axles together, forming a spool. This is great for off road use in mostly a straight line. For on road use, it's a bad thing.
With the Air locker turned off, you have an open differential. Which is great for on road use when traction is good - not so good for snow and ice.
There is no middle ground - it's all or nothing. Either open or locked, no in between like an LSD. Sometimes that's the perfect set up. And sometimes it's not.
