There is only one way to know for sure what you have, and that is to remove the cover or remove the chunk, depending on which Ford rear end you have, and look inside. ALL OTHER METHODS ARE UNRELIABLE. You can spin the alxes all you want, but you can be easily fooled by this method. Worn clutches, galded shaft, bent axle tubes and other things can cause a false reading. The only way to know for sure is to look inside.
