goat whisperer

I´m searching for a really bad crack on the right front side of the Goat when it starts to roll.
U-joints are ok, seems to be inside the front diff.
It only happens sometimes... but than the hole Goat shakes!
Something seems to stuck and suddenly dissolves!?

Mike asked me to check the pivot joints at the center diff., I´ll do that, but I´m pretty shure the terrible noise comes from the rigth front wheel / shaft or what else...

Any idea?
