Default 05 SOHC 4.0 belt squeak

The belt squeals the loudest when i turn the ac on. But it will chirp even with the ac off. I replaced the idler and the belt. Any ideas? Thinking its either the ac clutch or the crank pulley-wasnt there somthing wrong with the crank pulleys from this year?

+1 on the belt tensioner. I have a 4.0L Edge and that started squeaking on mine.

I did the whole front end maintenance thing - belt, tensioner, idler, hoses and water pump at once. The bearing in the belt tensioner starts to go and hence the squeak.

Not hard to change either.

Antifreeze or other contaminate on the belt is the #1 culprit. Works like rosin on a violin bow. Hold a bar of soap against the running belt and see if the noise quits. No, it won't hurt your belt and won't last long and yes you can lose a hand in the fan. That's all it was on mine and I just ignore it.

x3 on the belt tensioner. That was the problem in my 3.0 when it squeaked.
