I know what is. Ask me how I know. It’s the rear coupler splines and the shaft splines fretting. You will have to pull the torque tube. Either the coupler splines,shaft splines or both are worn. You can try tightening the the rear clamp bolt and retightening but not likely going to help. Check tube bearings and input bearing while your there. It’s not going to go away until you fix it. Dreading the job is worst part. If I can help let me know.
Thank you for the info. I did loosen and retighten the rear bolt and the sound went away. After a day or so, the sound came back but not as loud. The torque tube bearings seem fine but, as you mentioned, I will have to pull the tube to see what is going on with the splines.
