A rattle clatter issue

I have an 04Lj auto transmission, I'm getting a noise under the tub I can't pinpoint. It starts at around 30mph going up to 40 to 45mph, it seems to disappear after driving a few miles. It is not as bad if I am in 4hi. I have been under checking for any thing loose, and fluid levels. Maybe in the transfer case? Any help would be welcome.

Remove the front driveshaft and see if the noise goes away.

I haven't tried that yet but I'll give it a shot. Looked over the shaft and it looks fine.

Yeah that's right, I'm over 50 so I've been without for a while.

Okay I took the front drive shaft out checked it over good its in good shape. The noise is reduced significantly but can still hear it. The front pinion has a bit of slack in it, maybe like one sixteenth of the rotation.
