Default Help lb7 grinding

I made a post a little over a year ago and still have not been able to find the source, when i get up over 50mph and i coast and barely press on the throttle i get a loud grinding noise but it isnt all the time and sometimes sounds louder or softer i replaced u-joints, center support bearing, took apart transfer-case. I noticed marks all over the torque converter, also a shop told me they think is is my wheel bearing but not sure how the throttle would make it grind.
