thank you

You say you tightened the flang on the transfer case and it made it worse??? Possible bearing in t-case bad?? Put the back of the truck on jack stands and put it in gear, crawl under it and see if you can find where the sound is coming from using a screwdriver and putting it to your ear maybe...dont know though...

When my truck growled, it was the tranny. That is interesting that tightening the t-case flange made it worse...But I wouldn't expect a "growling" noise to be caused by a loose flange nut. I feel like they usually rattle. Growling is probably bearings in the tranny or t-case, but obviously we can't say for sure over the internet.

well i just took it in to the tranz shop it all checked out fine....
could it be mabey the rear axel its self because when i replaced the rear diff its was pretty much mangled only had about a half a tbs of oil in it?

Lol yeah, if the previous owner drove it with 1/2 a TBS of gear oil in it that might be your answer........... "lubrication 101- you've got to have some!"

How did the axle shafts look when you pulled them? Aside from the actual differential itself, nothing much relies on the oil, right? And he swapped differentials.

well all of this trouble turned out to be a crack in 2 of my other u joints and a very small crack in the drive line. thank you all
