The Stovebolt Site Forums The Shop Area Driveline posi rear end test with both wheels off the ground

only driver rear wheel will turn by hand and the other side will not move at all is this a posi or is the passenger side stuck

If you can turn it, and the other side does not turn the same way, it's most likely not a posi.

one side will not move at all

You may have a stuck brake. However, since you can turn the drivers side, that points to the differential not being a posi.

any idea how to release a stuck brake

If you can get to it, back the adjuster off. Then, if the drum doesn't turn free, try rapping the outer diameter of the drum with a hammer, that will usually make the shoes release from the drum. You'll definetly want to take a look in the brakes to see if there's any issues, like wheel cylinder leackage or broken/damaged hardware.

its a 12 bolt rearend i guess it would be wise to install a posi and rebuild everything
