Question Rear end gear oil?

What gear oil weight should i be using in a 8.8 posi trac axle?
also posi trac is when both wheels spin at the same time correct?

another question, since both wheels are spinning to make sure the axles are not wielded together would i know by looking inside the gear box?

1. 80W-90. I use 85W-140 in mine, but I have an Eaton Truetrac. Don't forget a bottle of friction modifier for T-lok equipped axles.
2. Theoretically, the wheel with less traction is not allowed to break completely free - Hence, limited slip. That said, the T-lok is the Chevette of limited slip carriers.
2. Well... Look for welds in/around the spider gears when you pop the diff cover off. It may look something like this.

ok good it didnt look like that when i had the cover off,it was pretty clean.
Just wondered about the traction cause i had it up on jack stands and when i spun the right wheel they both spun the same and the way.

Rear ends are usually not that particular about which weight of gear oil they use, but I'd go to another store that has 80W-90. That's the factory spec oil weight. Stop by the dealer and pick up a 4oz bottle of friction modifier. I usually put in one quart of gear oil, then the 4oz of friction modifier, then top it off the rest of the way with the second quart of gear oil.

You didn't mention what brand of cover you got, but they are all pretty much the same as far as I know. Here are the instructions for the Trick Flow version of the cover (the one I have). You will be able to find torque specs within:
