They don't have a posi, they have an open diff and limited slip diffs are not outdated by any means.

Only in True positraction which is very rare because you have a hard time making turns.
I stated it poorly. I did not mean they should both turn at the same speed -- not necessarily at all. What I meant was that it is not normal for one to be locked up and the other can be turned.

1. Never work on a car that is up on jacks. You should have timbers under it, not jacks or jackstands.
2. If you do not know that a car has a differential that does this, maybe you need expert help standing at your shoulder.
3. Sounds like your differential isn't differentiating or a brake is locked up. Get help.

Its normal if the truck isnt running and is in gear, in park, or you have the emergency brake on.

On my Mercury Grand Marquis - had the caliper lock up (mostly as could still drive car).

Had both calipers replaced and all went fine.
