Belt Squeaking...Random times....What to do?

It seems my belt is randomly squeaking. It sounds like small chirps coming from under the hood when driving. Sometimes they might last 3 seconds sometimes a split second. Totally intermittent. Is my belt to blame? I plan on buying a new belt and putting it on to see if that fixes the problem. Anyone else had this type of issue?

Thanks.

Replace belt and tensioner , both are wear items and more than likely need replaced

Ok, any idea how much work it is to replace the idle/tension pulley assembly? i know to release tension and change belt its a 15mm socket pretty much.

Looking at my AC compressor i notice a slight wobble when looking at it from above, is this normal? the AC works fine. also when it begins to squeek you hear a few clicks and its like it engages something and the noise goes away. not sure what is engaging though or wich part it is.

no it makes noise even when AC isnt on. But the bearings in there could be shot, even in "neutral" the AC would still have the bearings spinning. I cant diagnose if its alterantor clutch or AC compressor or what, thats alot of money to buy all those pieces.

I'm thinking I might have the same problem, I'm gonna replace the tensioner also just due it probably being factory. Was your jeep doing anything funny? Lights kinda dimming or anything?

Yeah, It maid nosie when ever the viscous heater or ac was running and my light's would sometimes dim when hitting brake peddle turning radio up etc that's why I replaced the whole unit instead of just the pulley got mine at advance auto.

Guys mine ended up being the water pump pully going out. THe water pump had not leaked a drop and showed no signs of damage. However, when i tookt he belt off and gave each unit a tug/twist the water pump was extremely loose. Replaced the water pump, noise went away and all is good.
