Re: sounds like a belt but... not a belt!!
I had the same problem. Thought it was my throw out bearing so I replaced it. The squeal went away for a about a day or 2 then came back. I did notice that if I slightly touched the clutch the squel would go away. So I tore it all part again and started inspecting things. I noticed the "fingers" on the pressure plate were pretty worn. And there lies the problem. The throw bearing had gone bad, but in my busy life it didn't allow me to replace it right away. I drove with the squeal for about 3 months before I attempted to fix it which caused A LOT of exessive wear on the pressure plate "fingers". So, I bought an RAM HDX clutch package for about $270 from AmericanMuscle.com , replaced the whole thing to include the pilot shaft bearing and another throw out bearing, had the flywheel turned (resurfaced), and behold NO MORE SQUEAL! In your case, depending on how long and how many miles the car has had this problem, you might be able to get away with just replacing the throwout bearing. But you will only be able to dtermine that after you got it torn apart. In my advise, and by learning from my mistakes, go ahead and replace the whole clutch kit while you have the whole thing apart and you can be assured the problem is completely fixed. Let me know if there is anything else I can help with!
