I was always under the impression that Jbodies were 1 wheel drive. I did a little burnout in front of my house yesterday and noticed two marks.
Tonight, I put a sticker on each wheel, then told one person to watch each wheel. I spun them. Both said they spun. They switched sides. Both said they spun again. I checked, and sure enough, I left two marks each time I did it. So what's up? Why are some cars equipped with an LSD. I'm seriously doubting the previous owner of my car had one installed.
My Cav is a completely base sedan:
No power windows
No power locks
5-speed
Similarities anyone?
I experienced similar things on my 02 Cavalier. It would spin both sometimes but most of the time only one. I think an open diff will spin both IF both wheel see similar traction conditions. I will tell you right now that you will see a day and night difference between open and lsd on a gravel road or at the track!

Yea, ummmm. I used to have a J-body...
How does it know if there are similar traction conditions. So at the track, would that mean I have an "lsd" or something that acts in the same way?
Let's just say if one is harder to spin than the other........the one with less strain will spin, thus making all cavy's open diff. Stock tires are easy to spin, you'll notice it more when you get rims.
What I want to know is if the Cobalt SS's lsd will fit our cars? I dunno just always wondered.

So a Cav can either be left wheel or right wheel drive depending on the difficulty to spin the wheels? At the track, will it be 2 wheel driven?
The Cobalt SS lsd will not fit our cars.
Open, lsd, and posi are terms to describe the gear set.
Posi is a limited slip. Positraction is the nickname in a Chevy car.
Open dumps the power to the wheel with the least traction. If one starts spinning then the other wheel does nothing. Open pretty much consists of the ring and pinnion and not much else.
Posi is locked up and both wheels spin but can have a differential speed between the wheels if the clutches slip. Posi consists of the ring, pinnion, and clutches between both sides. A posi is better at both wheels having traction but can slip and dump to one wheel. The design tries to limit how much energy is put to one side of the other but it can only do so much.

jack the front of your car up and put it on jack stands........ spin one tire forward...... if you have LSD or Posi, the other wheel will spin forward........ if it spins backwards, you have a stock open diff.
Try your burn out again, this time turn the wheel slightly....... one tire will stop......

ohh man are you sure you want to suggest that they turn there weel during a burnout.
"
boobs now with Riboflabin"
hahahahahahaha i was just thinking the same thing. my car can get em both spinning at the same time but as a general rule, only one goes. on a flat smooth surface, both will go if i'm perfectly straight. put water on one wheel, it'll do the spinning.
guess I should have added......
MAKE SURE YOU ENGAGE THE E-BRAKE, AND BLOCK THE REAR WHEELS

well you can see that 1 patch is darker than the other , that means 1 tire was spinning faster than the other
you have a open diff
a open diff in the right conditions will spin both tires , alot has to do with the way the chassis reacts when the tires spin
if you do a burn out , and see both tires spinning , if you very lightly apply the brake pedal , the 1 tire will stop , or slow the tire even more , that is spinning the slowest
