There are bearings, and yes they do get bad from time to time. Is this on your T-100? On a rear diff. there are bearings at the axle shafts where the shaft comes through the housing where the breaks are, and there are bearings inside the diff, that hold the ring gear carrier, and one where the pinion gear goes through the axle at the front, where the U joint it connected. Any of these can and do go bad, and will make noise when they do.
Welcome to the forum by the way
Just because the tires are new doesn't give them a pass, I'd have a shop check the balance just to be sure.
Bearings are like Kenney said, another possibility is bent axle/shaft, not saying you beat your truck, I've had this problem before after hitting a pot hole.

Another possibility to throw in the mix: broken belt in the tire. Can happen to both new and used tires.
Here is a video on rear diff. This will give you an insight on what is in there and how to take it apart. Although you diff may be a little different, all open diff.s are basically the same, as long as there is no locker. It is crucial that the main barrings and spacers go back in the same order that they come out, unless you re space the ring gear, and then the bearing caps still need to go back exactly like they were when you removed them. If you have to change the carrier bearings, you may as will change the wheel bearings while you are in there. Spend a little time on you tube learning how to re do you diff, and it can be done while it is still on the truck, When I did my 97 Chevy Silverado about 3 years ago, we did not remove the diff. from the truck.
If you just replace the carrier bearings, it is not necessary to re space the ring gear, as long as you use the same ring and pinion gear set up and the pinion gear bearing is good. Also the axle bearings will not effect the ring gear spacing. As long as you put the spacers and bearing caps back just like you remove them, you will be good. Here is another video.
Here is one on a Tundra. Although the carrier is a chunk and comes out from the front of the diff., the way the carrier go in is still very similar.
I'm in the shop trying to get the diff cover off, I removed the rear driveline, and took the 10 nuts off of the cover. placed a chisel and lightly tapped to separate cover. Its loose but it won't pull off? Do I need to remove the pinion nut before I can pull off carrier/diff cover?
No. Have you pulled the axle shafts? Or does your diff have a cover on the rear of it. If you are removing the carrier from the front (drive shaft side) you will need to pull the axle shafts to get it out. If it is just a cover on the rear side (bumper side) then it will just come off.
Here is a rear cover. The drive shaft is on the other side
Here is a video on axle shaft removal
I have not done a Toyota, but when I did my 1997 Chevy Silverado a few years ago. I did a lot of research. All diffs are basically built the same way. Ether the carrier goes in from the front, like most Toyotas, or the carrier goes in from the back like my Chevy. Ether way, you have to pull the axle shafts to remove the carrier.
If you have any other questions, please feel free to ask, and I will do my best to point you in the rite direction. I won't be up to much longer tonight though. It is after mid night here. We are 4 or 5 hours ahead of you in time zones. I am on most every day, so if I don't answer you tonight, I will tomorrow.
LIKE I SAID BEFORE, I CANT STRESS ENOUGH HOW IMPORTANT IT IS TO KEEP EVERY THING IN ORDER, SO THAT YOU PUT THE SPACERS AND BEARING CAPS BACK IN EXACTLY THE WAY THEY CAME OUT OF THE CARRIER. DO NOT MIX THEM UP OR TURN THE BEARING CAPS UP SIDE DOWN OR SWAP ANY PARTS AROUND.
Keep us posted on your progress.
You should be able to get it off with a screw driver or a pair of pliers. I would do this with the carrier in place, that way you won't disturb the spacing of the pinion to the ring gear. You don't want to have to fool with setting the back lash if you don't have to.
This video shows how to set up your ring and pinion spacing.
