Do pulleys often go bad on these cars?
 

It seems my A/C pulley went out on me a few months ago. I replaced the belt and it was most definitely the pulley causing the sound. I own a convertible so I just took it off and I put the top down when it's hot. But, now it's making a similar noise, probably from one of the other pulleys. So I'm wondering is this common? And is there a place I can purchase new pulleys at a reasonable price? Or is there a good aftermarket set I should look for?

By the way it doesn't sound like belt squeal. I also tried the soap bar trick on the belts to see if it was a noisy belt, but it didn't stop the sound, I think the belts on the car are in good condition.

might be an idler pully for ur p/s or something

most likely the bearings. i'm not sure who sells the replacement ones. for them.

Idler pulley bearings (you have 2 of them), can be purchased from auto parts stores like NAPA or Kragen. You can press them out/in from the pulleys with a hammer and something to pad the blows.

the bearings are not alot of money from the dealer or mazdatrix and will save you some guess work as to what may or may not work

That is really awesome. I never knew that. Thank you for telling me.
