idler pully(squeaking noise)

[hotshoe77]

i have been having a problem with a squeaking noise. it sounds like a belt squeal. so first i replaced the belt. it didnt help so i replaced the idler pully. went away for about two days and as soon as i did a little pull down my road it came right back. Should i replace all the idler pulleys with really good ones that have all 4 in a kit or should i be looking somewhere else where the squeaking could be coming from. my car makes about 600hp. i ws looking at the metco 4-piece idler kit w/dual ball bearing idlers from lethal thanks in advanced

Dual bearing metcos are excellent. If you have a lower, check the pulley alignments. Take the belt off and spin the pulleys to check the bearings. It would really help if you post your mods when asking questions.
