I'm having the same problem with my 87 MJ The only difference with mine is that it all started with replacing the PS pump. I replaced the water pump both idler pullies and the thermostat because it wouldn't warm up past 140 deg after the new h2o pump. A buddy barrowed a belt tension gauge and I had it way too loose but tightening it didn't eliminate the noise. I'm checking the pullies with a strait edge tomorrow at the suggestion of a freind to make sure the pulley went on the shaft of the P.S. pump the correct amount so the allignment between the pullies is good. I hope you guys come up with a fix so I can try it on my truck.
