Hey guys my 80 z28 came with 3.42 posi. When you turn the yoke the wheels spin in the same direction however when you spin one tire the other spins the opposite direction. It also locks up sometimes. Any idea what is wrong with it? Is it worth fixing? Or should I just scrap it. Any information would be greatly appreciated. Thanks.

 

if yours looks like this, get a new one

 

I busted it open and it looked normal to me. Have two 3.42s.
