It's the axel. I took it over to the shop I use this morning and we put it back up on the lift and gave it a good looking at. The axels banging right where it meets the pumpkin. there was a dime size hole in the boot protecting it.

We took a grease gun and filled it up with grease. Cost... free.

Drove it about 100 miles today with no further problems. Plan on getting a new axel for it in a week or so.
