I was workin on the car today, and was working specifically with the rotor. And was spinning it to adjust leverage for my wheel spacer lugs. And started hearing ticking, i slowed spinning down and the ticks slowed, and spun it fast as i could, and of course it sped up as well. It sounds like its either in the pumpkin, or right at the wheel hub. Vids below. Im pretty sure this is not good, but im not 100% sure.

Leme know if vid is too bad or etc, and i can get a HD video tommorow, its raining now

 

Step one, take the diff cover off and see if there is even any fluid in it. Sounds like its empty. Hard to tell from the video other then that. But that would be my very first step.

 

This was done today, had plenty of fluid in it, even had a little air pressure in it. No cracks/chips in the gears either.
