ZJ noise

I have a 95 Grand Cherokee w/ 318 and quadra trac that until recently was driving great. recently it developed a noise in the upper engine area and I nailed it down to the Idler pully between the alternator and a/c compressor. I replaced it and the noise sort of went away, the grinding screech of the bearing in that pulley went away but there is still this chirping sount that only is heard when the vehicle is in motion, the chirping will increase in speed with the engine rpm but disappears when the jeep is not moving, it almost is timed with the wheels rotating but as I have said will speed up with the engine when the throttle is opened. anyone have any ideas?

the belt does not yet need replacement. its not new but its not old ether. if it were the belt this noise would still be happening while parked.

Sounds right. the noise does seem to be coming from underneth the driver seat, right where the Universal joints are. and when I looked at them they are whereing a nice coat of rust and crud.

Checked that too but those accually have a slower different noise that goes away when the brakes are pressed. this noise does not stop unless the vehicle is not moving and when its moving it seems to be in sync with the drive shaft, which rotates faster than the wheels, right? Ill be pulling out the U Joints this weekend.

Turns out that it was the ball joint thats in the middle of the double cardan joint. it just needed some grease and a cleaning.
