    5.9 jeep, first time started in six months, and it has a loud chirping squeeking noise, only at idle. Any revs and it disappears. Noise is still there without the belt on. The balancer doesn't budge if you try wiggle it by hand. Could a crank bearing be making this noise? Or more likely, the balancer?

    So I replaced the balancer, no luck. Then I sprayed some WD40 behind the balancer at the seal, and it shut up. I then replaced the oil seal behind the balancer, and it was quiet for a few hours, now it's back. Wtf?
