1994 GMC K1500 5.7 w/auto trans. We are in the process of fixing it up and haven't driven it much.
It is supposed to have "Posi-traction" according to the option list. However, I happened to have the back end jacked up today, and when I turned one back wheel, the other one turned BACKWARDS like a vehicle with an open rear end. Puzzled, I jacked up only one side, and fired it up and put it in gear. It wanted to turn both tires, spinning the one in the air, and because it was in dirt/gravel, it turned the one on the ground on the other side too.
Now I'm REALLY confused. Will a worn out Posi do this; turn the wheels in opposite directions by hand, but try to go Posi under power??
Rebuild it?? Replace it?? I must have Posi...
Thanks!
