just remove the belt and try to spin each pulley by hand... if you come across one that sounds like its shaking replace that one. i dont think its necessary to replace them all.

Ok cool .. cause the squeal will go away if I spray some belt dressing but then itll come back
Here is a video that I made the other day that can relate to this post. I believe it is the third pulley that I spin in the video that you can tell is bad.
Also, I would replace the belt. If you can find a Goodyear Gatorback, they are really good belts.

Dealing with the exact same thing right now - anything special I need to know about the belt removal? Forgot to add that I have a 2.5.

Nothing to it. If yours is like our 97 4.0, you loosen the pulley bolt (the one in the center of the pulley) below the p/steering pulley. Look close and you'll see a bolt head sticking out sideways to the left of the pulley, that's your adjustment. Back off the bolt till the belt is loose. Remove old, install new, wise to spin the tensioner and idler pulleys to check for bad bearings. Tighten adjuster bolt, you want approx 1/2" deflection if you push hard on the belt at it's longest span. Tighten the pulley bolt and you should be good to go.

This is one way, but if your 99 is anything like my 2001, all you need is a 1/2" drive preferably with a long handle and there is a square slot in the tensioner, place the drive in the slot and pull to the right... this will release the tension on the belt and it will slip right off. Check to see that your jeep has the belt routing on a sticker near the radiator, if not make sure to take note of the routing that the belt makes around the pulleys

Just tighten it... DON'T spray belt dressing on it. No. No. No.

You don't need a part number. Take off the belt and take to an auto parts store. You just need one the same length and width. Once off, check your pulleys. If they all spin freely it's just a worn belt.

I don't think you understand that your belt us perfectly fine. Do you have cracks that stretch the length of the belt? Down the belt, not across it. If not, then your fine, just tighten it up.

Can you over tighten a belt?

I dont see any cracks but the top of the belt has some smooth markings from spinning

The way I heard it is that you want about 1/2" of give at the widest point between the pulleys (when pressed on with your thumb). I don't know for sure, but when the belt has more load on it when driving I could see it failing from stress if it is extremely tight.
