Belt noise
Ok, heres the problem. My belt on my truck sounds like a cricket. It chirps and if you watch the belt at idle it kinda jumps on the alternator pulley, which is where i'm guessing the noise is. First i figured it needed an idler pulley, since it needed it anyhow i replaced it, but it still chirps. Anyone have this and solve it.

Thanks guys

I was having a problem recently with a chirping related to the belt as well. I eventually saw that my air pump pulley was wobbling like crazy at idle. I finally got around to replacing the air pump, thinking maybe the shaft got a lil' warped. It had no effect on the wobbling, so I took the pump back off and took a hammer to the lil' brace that attaches from the back of the pump to the timing cover. It fixed my wobble right away. I don't know how it got bent, or even IF it got bent, but by reshaping that brace it fixed the wobble which stopped my chirp AND me shredding belts that kept jumping grooves.
Check yours, kinda doubt it's your problem, but ya never know!!

This is an EXTREMELY common problem with Ford Truck Serpentine belts. I've never had a Ford truck that didn't chirp sometime. Also, it happens as much on my 460 as it does on my 302's. Armor All on the belt has helped most of the time. I used to use Triflow but found the AA works better.
When I'm in a campground we Ford Motorhome owners get together and all tell what fluids we use to quiet the 'crickets.'

is it a bad bearing in one of the drive accesories that can hang it up a bit, i had a friend once that had a smog pump lock up, also any wobble at all when u wiggle the fan/waterpump. i doubt it but figured i would mention it, i sprayed white lithium grease in my idler and it stopped chirpin, suppose graphite would work too but a high quality that will stick , silicone tends to wear off

If it is a bearing squeaking, it will soon fail and it will be easy to find where the problem is, at least. The only reason bearings squeak is that they are dry, and since they are closed face, spraying on something will be temporary at best.
Armor All on the belt will allow it to just slip slightly, but as long as the belt tension is fine, it will not hurt anything.
I spray mine from the bottom of the engine while it's running where the belt contacts the lowest pulley. Having one of those little straws on the end of the spray bottle helps a lot in getting it on the belt.
