Yes it Would be a noise or vibration & you can tell by grabbing the drive shaft and moveing it up & down, side to side. Does it vibrate at all durring certain speeds? and have you replaced any of the u-joints? Fyi carrier bearing /center support bearing cost $122.00 at yer local parts store. I just replaced my factory one @ 99,266 mi

sorry for hijacking, i have a vibration at 80-90 kmph, no where else, worse when im on the gas, less but still apparent when off the gas. i read the carrier bearing has some play in it, like an inch or so, i can lift my drive shaft in the middle, like a half inch or so up and down right near the carrier bearing, didnt check side to side though..
The carrier bearing is enclosed in a flexible bushing that has approximately .375"-.500" of play in it during normal operation. Flexing the driveshaft around within these tolerances will not tell you if the actual internal bearing is failing. I would imagine that you would hear a grinding, squealing sound if the bearing was the culprit.
I actually haven't heard of anyone having one of these bearings fail on them. Usually, the symptom is driveline vibration that can be traced back to a degraded bushing.
What condition is the bushing in? What makes you think the bearing is failing?

Just traded in a tacoma with 266K....replaced the carrier bearing twice in that time....in both instances, the bearing began to make a rather high pitched howl. I replaced both times with aftermarket parts, and the quality was poor. The factory part had solid rubber surrounding the bearing, and the aftermarket parts were hollow rubber (kinda like a tiny tire). original lasted about 150K, and the aftermarket needed replacing after about 80K. Pretty straight forward install, but needed a gear puller to remove a spline flange to access the carrier....not sure if the tundra is the same, but probably best to have the puller handy. I would suggest the factory replacment part if looking for a longer term fix.

PS....there will likely be a depression on one side of the carrier....it is my understanding that this points toward the ground to allow moisture to drain.

The support bearing is making a whining noise at speed above 20 mph. It would come and go so finding what the noise was took time but I put the truck on jackstands after driving for a while and could listen under the car with the drivetrain moving. The whine / hiss sound is the center support bearing. The best price I can find on a OEM part is about 129 and the aftermarket parts prices are really all over the place. The lowest price DEA CENTER BEARING in the 30 dollar range with Tezuka being around 110. Anyone heard of Tezuka? I also found National and Timken both about 85. Any thoughts on the quality of any of the above.

Mine went at 100k, made a high pitched howl just like joel's above did AND also had 3 splits in the rubber and bearing locked up burning the rubber bushing.
The parts store did not have one for a tundra but did for a tacoma, we crossed the part # and they were the same so I have now added another tacoma part to my truck

I would be leery about going aftermarket on this part. I'd try TSer mustang @ Findlay and see what kind of pricing he can get for you.

I have a squeak, squeak, squeak coming from the driveshaft only when in gear moving forward, and when I go to neutral it stops. Would this be the support bearing going bad? Can this be replaced with basic tools in the parking lot of my apartment or does it take more than that?

In my experience squeaks coming from the driveline is a dry needle bearing in one of your driveline universal joints. It could be a leaf rubbing as the suspension loads or unloads too. When my carrier bearing went bad it was actually the bearing that the lube had dried up almost making a rubbing scraping sound. On my carrier bearing the rubber surround was fine so rubber going bad might make a different noise. I have never replaced one of the driveline universal joints on my tundra (lube them every other oil change or so) but I have replaced a fair amount on my older Toyota 4x4's and they typically squeaked when you put the first put them in gear and loaded the driveline when they are dry and in need of a change. When was the last time you lubed your driveline universal joints?.
Toyota does not make their own bearings, they buy from an outside manufacturer. I would not be at all afraid of aftermarket bearings, just remember to stay away from the really cheap ones.

Somewhere buried in the old TS there is my post where I took apart the carrier bearing and it was a Timkin bearing I believe. I posted the actual bearing number and it was quite expensive by itself when I looked it up. The original toyota rubber support was in perfect shape and mine failed because the lube had started to dry up. If you dig you will see many who replaced their carrier bearing with the 30 dollar ones and they failed very soon after replacement because of rubber failure. Now this might have been because of low quality parts or it could have been because the drive line wasn't straight. When you replace your driveline be sure to pull a string from the transmission to the rear diff and using the carrier bearing adjustment range get it as straight as possible.
I’m have a tough time finding this noise.
New to me 2005 Tundra. When under load
(Adding throttle) the noise is there.
If coasting, there is a howling noise.
Best description is a window is cracked open.
It howls but not overly loud, just enough to annoy me.
I read up on how to check them.
It’s not very definitive as to go-no go.
I have 77 Thousand total miles.

Like 5 Speed mentioned, I placed my truck on 4 jack stands and threw it in Drive and got out and listened for where the noise was coming from. It was the carrier bearing, I sprayed the snot out of it with an aerosol lube and the noise was gone until I replaced it. It was a very noticeable squeal that was associated with acceleration and deceleration.

Usually when the center bearing is worn out the U-joints are worn as well, putting more stress on the center bearing and hastening its demise. My mechanic recommended always replacing U-joints when replacing center support bearing, I do so, removing the shaft myself and sending it to Oceanside Driveline Shaft Removal | Oceanside Driveline | United States. They disassemble, new U-joints, new carrier bearing, service slip yoke, clean, paint, and balance. Good as new! Here is a link to my build thread with more details: https://www.tundras.com/threads/the-6-million-dollar-tundra-revival-story.84992/#post-2171272.
On my Tundra the only symptom was a rumbling rhythmic vibration at low speed low rpm under load, like going up a hill. I have had many other vehicles with similar feeling, light vibration all the way up to feeling like someone is bumping under your seat with a large hammer. 'whap whap whap whap'.
I suppose there are two types of failure, the bearing that spins and the rubber that holds the bearing. I am talking about the rubber failing along with an imbalance in the driveshaft or play in the U-joints that causes the rhythmic vibration.
