Pulley squealing

[army_man1014]

The last week or so I noticed something was squealing under my hood. I really couldnt pin point where it was coming from so today i decided to take off my belt and then the pulleys and clean and examine them. WEll my belt looks good but i noticed the noise was from the pulley below and to right of s/c pulley. I put some oil on back of it installed it and still was making squeal.

then i noticed if i loosened the bolt holding it then the noise will go away and when i tightened it then it started again. I cant leave it loose or the bolt will back out.

What do u guys think this is. Bad pulley maybe!

What brand of pulleys do you got? Sometimes even the aftermarket ones go out, I have a set of billetflows and one of them was squeeling like a bitch awhile back. Bearings went out!

dont know the brand of pullies.. sry i could take a photo if that would help. will it do harm if i still use the car?

Is it and Aux. Idler or an actually idler? Take a pic if you dont mind, if I was you I would replace it asap, (stock and some Aftermarket) idlers have been known to shatter and cause some serious damage!

Mine is doing same thing!!!

Its billetflow, the bearing must be going bad. I would either take the Aux off or replace it if I was you! Just incase!

I've replaced mine with bearings from napa. Just use a press or get ome one to do it for you. It's not a big deal. The bearings are around 8.00 or so.

I tried repacking mine one time but they just continued to leak after that. I got tired of cleaning the grease fillm and just replaced them.

I used these bearings: SKF bearing.... part number: 6203-2RSJ

I also saw a reference to these: Federal Mogul and part number is: 203-FF
