Brett,
The orientation of the drive disk looks correct. I would pull the drive disk and carefully examine it to insure that the hub is not coming loose from the mounting plate. The springs can become loose and these things can come apart. When they fail, you are really stuck.
While it is off, verify the part number and make sure it is the correct one for your particular engine. While your are at it, make sure your transmission model was one of the approved options for your engine. Just because it can be bolted on does not mean it was designed for use your particular diesel.
I only mention this because you have not posted the specifics on your engine, or any of its history.
I highly suspect the drive disk is failing. If it is, you received an early warning and can change it at your leisure!
BTW, I just changed mine last fall at 1,600 hours because of some chatter, the springs were loose from some hard shifting I suppose.
