ok.
BJ went out to the garage and shook the chit out of 'em. I saw nor heard any strange wiggling in the joints. I did notice on the back side of the tranny/transfer there is what looks to be like a metal donought....where that goes in it moves ever so slightly....not the joint, but that metal disk shakes side to side, very lil, albiet it does move. Strted the jeep and tried going in forward then reverse and it can def be heard...
