I was checking out a 10 bolt rear in a freinds car.And when you turn one wheel the other one dont turn.but if you turn them both at the same time the yoke speeds up.It goes alow if you turn on wheel but gets fast if you turn them both.I know a posi both wheels turn the same way,and a single trac,the turn opposite,but I have'nt seen one that the wheel thet you are not turning dont turn at all. :confused:

It is just an open rear. The pinion turning instead
of the tire is just the force taking the path of least
resistance.

I agree.

My warped drum brakes cause mine to do the same thing (1 wheel sticks).

Try it with the car in park.
