differential help needed
Ok, like Crazy said, that is an LSD. Here is how you have to align the gears in those....
First, the carrier needs to come out of the axle housing. Next, you'll need to get a 4.5 inch long bolt with some 2.25 inch diameter or bigger washers and a nut. Then, you'll compress the clutch packs on one side with the bolt/washers/nut and remove the axle shaft from that side, and put the carrier back in the housing. Slide the axle shaft into the open end of the carrier (the side without the bolt) and turn it (you might need to put the wheel on for more leverage. Once the spider gears are realigned, you'll take the carrier back out of the housing. If the thrust washers that are behind the 2 spider gears are out of alignment, you'll need a second bolt to compress the other side of clutches and with both sides compressed, you'll be able to slide the thrust washers into place. Then uncompress the clutches by removing the bolt and everything should remain where it is. Slide the pin back in and reassemble.

Wow, a psychadelic differential, ha ha ha!
Hey guys, that's great help, thank you! I'll post back if I achieve a succesful outcome. A little bigger job than I originally intended but you live and learn.
Thanks again!

Just like some engines are called Magnums and some are called Hemi's. For a full list of LSD factory names check out that link.

I forgot to add one thing to my post... when your trying to turn the axle shaft, you'll need to hold the carrier still. I did this by putting the pin part way in the hole, but not far enough to get in the way of the gear, and let it hold the carrier still by pressing against the axle housing.
Dude, I just rebuilt a trac lok LSD for my new truck, and yes it absolutely does have springs... just not coil spring pack like the suregrip. It has what is called belleville springs. They look like one of the clutches, but are thicker, make of spring steel, and cone shaped to put a force on the clutch packs. There are several kinds of limited slip differentials, but they all have springs to put a pre-load on the clutch packs. Then, when you get on the gas, the wedge-shaped teeth of the side gears "ride up" the wedged-shaped teeth of the spider gears, pushing the side gears out which applies a greater force on the clutch packs.
