Have a question about these transmissions that maybe someone who's had their share of them apart can tell me. I had a rough growling noise only during travel, any gear forward or reverse. Pretty loud and constant. I disassembled the entire rear end and found a lot of metal shavings as seen in the last pic as well as a part of what looked to be a bearing cage, I lost it unfortunately. Problem is that I was expecting to find a bearing or something that was bad but nothing. Carrier bearings, pinion bearing, input to gear reduction bearing, all fine. Anyone got any ideas? Thanks
