T56 troubleshoot banging

[grandkodiak]

There is a rhythmic banging that you can hear and feel in the very rear of the tranny, not the bell housing but further back... any ideas? not loud enough to hear in car (atleast over the exhuast) and it doesnt have any driving symptoms, no hard shifts, no running wierd... and its not the clutch....

Working my way back worn bearings, worn tail shaft/slip joint, worn u-joint, worn u-joint, worn yolk, worn bearings in the rear end.
