I need help!
I need to find a way to fix my belt tensioner pulley by myself. I have the part but I cannot find anything on the internet to fix it. I have two children who are two and under and I'm pregnant. It's my only vehicle to go to doc appointments, store, etc. If anyone can help I would sooo appreciate it.

Replacing the tensioner is a very easy job. First get a wrench on the bolt in the center of the pulley and torque it over so you can remove the belt. Next, make sure you've got a long wrench (I believe its a torx. Star-like pattern on the bolt) and try to the torque the lower nut on the spring assembly way over until it breaks loose. If it will not budge, get a breaker bar (any kind of long, strong, hollow metal pipe) and put it over the wrench to get more leverage. It will eventually come loose. Once it budges, you can lose the breaker bar and loosen the nut the remainder of the way. Remove the tensioner and put the new one in its place. Torque the nut back down as tight as you can. Once its tight, pull the tensioner back over to reinstall your belt, and you're finished! Hope that helps.

I just realized that you said you needed help with your belt tensioner "pulley". I assume this means that you want to replace just the pulley and bearing on the tensioner but not the tensioner itself? It might be worth while to replace the entire thing if it is original to the truck because after so many years the spring gets weak and causes the tensioner to bounce around while the engine is running. Happened to my truck a couple of months ago and it gave me a real annoying squeal. Other than that, I'm not sure how the pulley comes off the tensioner, I'm sure if you strapped the tensioner into a vice and really rhomped on the nut with a wrench it would come loose and allow you to swap out the pulley. Let us know if you have any problems.

It was cheaper for me to replace the entire unit ($15 from an Autozone).

If, as Skan says, you are just replacing the tensioner pulley, the bolt is 15mm but remember that it is left-hand threaded! In other words, you turn it clockwise to loosen it. Counter-clockwise to tighten it, and to move the pulley to install/remove the serp belt.

RE:tensioner pulley
I ended up taking the whole belt tensioner pulley assembly out...if thats what it's called. I just now read that its backwards for loosing it or I wouldn't have taken it out. When I did take it out though, there was a rubber like washer/
seal thing that came with it? Is there supposed to be and do I have to buy a new one or will it come with the whole assembly when I go to buy it tommorow? Oh and one more thing...could it have been the reason my truck would vibrate when it went up hills and tried to shift and everything? Cuz if it's not broken I'll just put it back in now that I know it's left hand threaded.

Did the rubber washer come out with the tensioner or when you took the pulley off the tensioner? Because I don't remember a rubber washer when I took the tensioner out, now did I get one when I bought a new tensioner.
And I don't believe that a bad tensioner could cause your truck to vibrate going up hills and when shifting. That sound like either torque converter chatter (which the E4OD transmission is prone to doing) or a problem in the driveline. Is the truck lifted? I had a shudder on acceleration and going up hills due to my carrier bearing never being shimmed down after the truck was lifted. Otherwise it would most likely be a bad universal joint.
