2000 A4 WS6 -- How do I know if I still have limited-slip??

[ScrapMaker]

I purchased this 2000 WS6 back in November, and I was curious... don't all WS6's, well, Trans Ams even, have some type of limited-slip differential?

I ask this because most of the time I burn out, the tracks are different lengths... which I found strange..

also when I had the car up on the rack, if I turned one tire by hand, the other went the OTHER direction... just like an open-end.

do posi's move the other way if you push it by hand? maybe they only 'lock' both wheels when there is pressure from the driveshaft??

I know the car had the gears replaced by the dealer a few years back, and I wonder if they pulled some shennaighans??

I know the fluid needs to be changed in the rear end... but can having old fluid/wrong fluid cause this reaction? I didn't think that it could cause one wheel to go the other direction...

Thanks,
Steve

the stock torsen zexel posi's that came with the regular trans am's, ws6's and z28's i believe work like that. they dont have cluthes just gears in them and work off torque to give each axle output. the ss's and firehawks came with the heavy duty clutch type posi's.

the regular zexel posi's since they have only gears i dont think they dont need additives. but the correct fluid is always a good thing, 75w-90 i believe.

Hey thanks! I was worried for a second... because my brother has a clutch-based limited-slip in his 1974 Chevy Nova, and both his wheels go the same way when you rotate the tire by hand...
