Chirping / Squeaking When A/C on & Turning Wheel

Like the title says, it seems as only when my A/C is on and I make a turn I get a quick squeak or chirp. It sounds like a belt to me but I'm not too sure. Has anyone else had a similar problem?

I just ordered a slew of parts and hope to have them by this week so I can install this weekend. (Champion Plugs, EGR, PCV, MAP Sensor, Billit Catch Can, Air Filter, Oil Filter, Serpentine Belt, Seafoam Treatment & Fumoto Engine Oil Drain Valve) Hoping this solves a lot of my MPG, throttle response, noisey engine issues.

Which jeep/engine do you have? Sounds as the accessory belt, did you check the tension? If its stretched too much, it can be that the tensioner is at its limit. Wait until you have changed the belt.

Sorry - 2008 5.7 I should have the belt this week. I'll post up after I throw it on.

It also has a constant low volume squeaking, I assume its a pulley because its non stop but you can only hear it when you're in front of the truck @ idle. Does this sound familiar, correct? What are some solutions? I think my WJ had the same constant squeaking.

Check the pulley bearings when the belt is off. The bearings tend to loose the grease over time and the bearing can seize. Just spin each pulley and hear/feel if there are rough parts or strange noises.
