Stopping Jeep Cherokee Belt Squeal

My 1989 Jeep Cherokee's serpentine belt is squealing horrifically. Nothing I have done will make it stop for longer than a few minutes.

My Jeep, with the 4.0l inline-6 engine, emits a terrible squealing noise whenever the revs get up above an idle, and a steady chirping sound at idle. The squealing increases in pitch and volume as the engine revs go up.
In the last few months I have replaced the water pump, idler pulley and the alternator is new. The serpentine belt was replaced at the same time as the water pump.
Spraying the tiniest amount of lubricant (of any sort - WD-40, silicone lube, white grease) on the belt will stop the noise temporarily, but it usually starts again by the time I get the hood closed and get back in the car.
It is not a belt tension issue as I have checked that the belt tension is correct, and experimented with tighter/looser tensions.
It doesn't seem to be having any detrimental effect on the operation of the engine, but it is simply becoming increasingly embarassing to drive around in with the constant noise.
I have read in places that the harmonic balancer may be the culprit. Before I shell out the cash and scraped knuckles involved with replacing the thing, does anybody have any other insights of suggestions as to what may be causing the squealing noise?
