Belt Tensioner Pulley...Now with Vids... my car has been squeeling and I know its coming from the belt tensioner pulley area. My question is, do I need the tensioner pulley for the main drive or the tensioner pulley for Serpentine... when I went to Auto Zone and asked for the belt tensioner pulley, both of those came up. They didn't have them in stock so I couldn't compare them there.
From what I've found online, they don't look any different. But I don't want to take it off, find out its the wrong one and have to put the original one back on, then go get the other one and do it all over again. Figured I'd try buying the pulley alone before buying the whole assembly. My belts are fine, they've been replaced already and don't seem to be slipping. I've tried belt dressing, and sprayed brake cleaner (old trick I was told to try) and that area still squeels.

well I replaced the pulley, and that wasn't the problem. So I put the stock one back on and ordered the whole belt tensioner assembly...only problem is, this is the part I need. Sorry for the size...I copied the pic from someone else and just circled what I needed...
This is what Auto Zone has...
http://autozone.com/R,APP1024326/veh...ductDetail.htm
they don't match up to me. The one on my car doesn't have a hole for a bolt unless it is covered up under a plate somehow. The one from auto zone has a place for a bolt as you can clearly see...I know there isn't a hole for a bolt b/c I didn't see one when I took my stock pulley off. Also, how am I suppose to get the belt tensioner off, if I can't get to where the bolt is? I've searched this topic, and have found no results. So don't start flaming me with a search thread...thanks

. But yea, got the part switched out. Ordered the main drive assembly. Waiting for it to arrive so I don't have to listen to the car squeel anymore . I'd delete this whole entire thread just because I felt like a complete idiot trying to figure this out, but i'll leave it for future "newbs"... 
Thanks for the help guys

I'll give the greasing thing a try. Although I really believe the squeaking is coming from the housing of the bearings. Might try to take the main drive assembly off and grease up the bearings before I put the new one on...I'll let you guys know how it turns out.

Alright so I took the stock belt tensioner pulley assembly off and greased everything up and it didn't solve the problem. So I really don't know WHAT exactly could have gone bad on the main drive assembly to make it squeel the way it does. I got a video of it, and how it doesn't squeel so bad when the AC is on, so i'll post that later tonight once I get cleaned up, etc...

Later yesterday afternoon I rode down to store and met up with some friends and when I was pulling out of my house it didn't squeel until as soon as I hit 1500 RPM's. But then once I hit 2000 rpms it stopped and didn't squeel all the way to the store, even when I had to stop at lights and go again, it never squeeled all the way there.
But yea at the store, this guy with a ragged out fox body mustang 5.0 comes by like 6 times (no joke) revving his engine and crap and asked to run so I did. (I think you all know how that went...) ok back to my problem...
Once again, when I hit 1500 rpms it squeeled and stopped at 2000 again. Even when I ran the mustang, it didn't squeel at all. Heck all the way home from the store it didn't even chirp. But when I had to run to my grandparent's house later last night, it started back again, except its actling like it did before I greased everything and its squeeling like crazy, from idle, all the way to 6500, it just squeels constantly...
heres 2 videos, one without the ac, and one with the ac being turned on. These were recorded after I greased everything up. I'm sick and horse so I sound funny in the vid. but yea, enjoy...

so on the way to the blue print shop about 30 minutes ago, it squeeled all the way there. I left the car running while I was inside, and on the way back, it didn't squeel anymore...

Just take both your belts off and turn everything. You've already replaced the main tensioner pulley, so you can bypass that. Check the main drivebelt idler pulley, then the a/c tensioner and idler. Pretty easy to do, just turn them all by hand with the belt removed. You should be able to tell which one is making the noise pretty easily.
Also, you don't really have to replace the pulley. You can just pop the dust cover and regrease the bearings in a couple of minutes. I made a thread about it a while back, if search is working right now.
