help! pulley noise!

My buddy's 1997 7.3 is making a terrible chirping squeaky noise from the engine pulleys. Seems to be everywhere... Does it at all engine speeds. The crank pulley appears to be wobbling, could this be a possible cause? Someone suggested the tensioner also... Any advice or suggestions on what to check or look for would be appreciate it!

spray the belt with belt dressing..or even a quick shot of WD-40 or the like. . If the noise completely goes away replace the serpentine belt first before chasing pulleys. I replaced every pulley on my 96 one by one, only to still have the damn squeak..finally bought another new belt (had just done one 4 months prior from Napa, and it started squeaking again, so went with a Ford belt..problem solved)
