Silly Question about Rear Diffs . . . The other day I was working on my 2002 SS, and had the rear end of the car jacked up and on jack stands.
The question is, when I turned the one of the rear wheels the other wheel did not turn, isn't it normal for the other tire to spin the opposite direction when the other tire is turned?
Just want to make sure the diff isn't fubared!
And to note it is the stock diff with aftermarket 3:73 gears

Quick way to check your posi....
Find somewhere away from the Popo and do a quick burnout.
Look at rubber lines on the pavement.
2 lines (both wheels spinning) ...posi is fine
1 line (only one wheel spinning) ...posi has a problem
First thing to check if there's a problem is the diff fluid (amount & cleanliness).
Maybe even check that before the burnout test.

Your 2002 has a torsen rear. With the rear in the air, spinning one wheel forward (with the car in gear) will spin the other wheel backwards. If the car is in neutral, it may not spin the wheel at all and just turn the driveshaft. This is perfectly normal for a Torsen rear. Don't worry, it's not broken.
Have fun!
