What do you mean how does it work? It's really no different than any other differential http://auto.howstuffworks.com/differential.htm Check that link out and see if it helps.
There are multiple types of posi, one of the more common ones has a disc and a friction plate. the disc will spline to the axle and the friction plate will lock in to the differential with tabs that stick out. When the differential moves the axle moves as normal, but the friction from this disc / plate arrangement tries to spin both tires at the same time. When you go around a corner the friction of the disc and plate are overcome by teh friction of the tires. I hope this helps, I could describe much better with pictures.

By "normal", that would be an open rear end. A "limited slip" rear is when both tires spin at the same time. The "Dana" would be the same, but it's much more beefier, and desireable if you plan on pounding on your car. The downside of the Dana is the price, once you find one.  :scared:

Dana is a posi(traction) rear end!

Are you sure you understand?  I think you are saying that a Dana "is" a posi rearend.  Am I right?

Because if I am, then you are misunderstanding what MEKrunner was saying.  A Dana rearend is the version of the rearend because of the manufacturer not because it is a posi.  It measures 9 3/4 inches on the ring (gear) in the Chrysler cars of the 60's/70's.  There are other Dana rearends that were used on makes and models of cars and trucks.  The Dana refered to in the Mopar cars is called a "Dana 60".  The Dana came with a suregrip (posi) unit installed.

I hope this helps.

Dana is the brand name. 40, 60 and so on is the series.

The brand name for the 8 3/4" rear is Hotchkis, but I am not certain on the spelling.....

We like to call it one wheel drive.  :lol: Yes, that is how most of them came from the factory(open rear end). I have the sure-grip, but given my car was a base model, I'm sure that was put on later in it's life. I'm NOT complaining though.    :burnout:

It's really funny when you see all of these 4wd trucks driving around. Most of them are 2wd with one drive wheel in the front and one in the back  :grinno:
