Throw Out Bearing
Just replaced the clutch on my 02 Taco about a month ago, Paid $400 for a aftermarket clutch, flywheel and throw out bearing. Thought it was a smoking deal the Guy also said it was made by Exedy. Anyways the Bearing is squeaking now, and its starting to annoy me. Is there anything I can do other than dropping the tranny to stop it.

Yeah there's your problem. You might be able to grease it with a spray lube, but putting some thick moly on everything while its apart is much better.
Some of those points are hard to get to just going through the clutch fork hole, you might have to drop the tranny to do it right.

Are you sure it's the throwout bearing, they usually only make noise when the clutch pedal is pushed in as that's the only time they're under load.

If it makes noise when the clutch is not depressed, then its the clutch fork making the noise.
The clutch fork has a slight amount of play in it when it is not under load, which is when the clutch is not depressed. The fork will dance and make a whining noise. This noise is not noticeable when the fork pivot contact point is lubed properly.
I don't mean to be a wet blanket, but that's a pretty important step that you left out of your clutch job, proper lubrication on the points I mentioned is key for smooth and quiet clutch operation

Well, like I said you could try your luck with a spray type grease and go in through the clutch fork hole. It's not going to be easy to hit all of those points, but it could be done with an extended straw and some patients. You just won't be able to grease the tip of the input shaft, but its too late for that.
I would recommend removing the clutch slave and completely removing the fork boot from the bell housing. This will give you the best shot of looking in there with a flashlight and seeing what you're doing.
Try to lube 3 spots on the fork:
-2 points that make contact with the release bearing
-1 point on the backside of the clutch fork that it pivots off of (staring right at you when you pull the boot)
Then try to hit the front of the release bearing, and the front bearing retainer that the release bearing slides on.
It would be best to drop the tranny and pack some moly in there, that stuff is extremely water resistant and clings much better to surfaces, but you gotta do what you gotta do

Sorry to bump an old thread but is it bad to keep driving the truck with a squeaky throw out bearing? I am going to replace the clutch within the next month or so and my clutch pedal just started squeaky yesterday.

Does it squeal when the pedal is pressed?
The t/o bearing is probably dry, and on short countdown to totally falling apart and seizing. Once that happens, the noises will get worse and it will start wearing the fingers on the pressure plate when the clutch is pressed. If you're going to replace the pressure plate anyhow, still not a huge deal, although the number of times you'll be able to press the clutch before the pressure plate fingers physically wear out from having a stuck bearing thrust against them with a lot of pressure is limited.

So it's not that noisy when the pedal is all the way down, and not noisy when the pedal is all the way up, just when it's slightly down?
No problem, it's probably just in the very early stages of going out, should last another month easily.
You'll know when it really starts to go out.
But again, even then the most damage you'll do will be to the dead T/O bearing and the pressure plate, which you'll likely replace with the clutch kit anyhow.
