I have the one in the second link, but for the alternator on the 6.0L you can really just lift the belt on and off the alt without messing with anything. Or use a pry-bar to lift the belt up and off like how is shown in Rusty's link above. But if you feel like you need to, either of those tools will help you set the tensioner kickstand (pics below) that keeps the belt slacked while you change out the alt.

When I change the alternator in the 6 liters, i tie a rope on the belt and tied it to the hood latch up top to keep the belt from falling down.
I then take off the two front bolts on the the alternator, and then loosen the back bolt slowly. The alternator will start to tip forward (no, it doesn't strip bolts or anything like that) and then the belt will loosen and the rope will keep it from falling into the engine. I just reverse the process when putting it back in. Works like a charm for me everytime. I've done dozens of them.

If it was me, I'd replace it. It was intermittently failing in operation, ditto when tested in the truck and you think something has changed because it can pass a bench test? It intermittently "passed" in operation and in the truck (that is the opposite of sometimes failing).
No question in my mind it'll go back to the same: sometimes works and sometimes not, if you put it back in.
replace the dying alternator...

I pulled up on the belt and used a bar to tap the stand under, then a piece of string or rope to hold the belt up and keep on all all the pulleys. If you have trouble, take out the passenger side batteriy, be sure to cover the cables, and then you can have someone reach down from the battery side and hit the kick stand under while you pull on the belt. It's a hard pull, but stick with it.
