No doubt. I was under there investigating an ongoing (and increasing) whirr from the driveline. I've suspected the forward u joint or center bearing for quite some time and this was the weekend to tackle it.
Once under there I (re)noticed the wet drive shaft brake drum and decided to open here up. My first center bearing is pretty loose. Replacing both tomorrow.
I found some more info. Part number for the center bearing and u joints
