Oh bad news. The left axle is trashed and the bearing obliterated. Looks like the pinion gear bearing went bad cause its loose. I did not know this until I took everything apart. I am not sure what to do at this point but my neighbor thinks I should get a doner rearend if I want to keep the Jeep rather than to rebuild. I am note sure what went bad first. The carnage is awlful. I guess the vibration was too bad but I did not noticed it. Crap.
