need suggestions on weird noise.

I think I'd think twice about the kevlar bearing, I've seen many posts with issues.

What issues? I've been so busy with work and studying and family issues that I've missed more than not over the last few months, but I hadn't heard of anyone having any problems with Kevlar pilot bushings. I put one in my truck when I did the ZF conversion in '05 and haven't had a single problem. Maybe I got lucky?

And, Drew, that's a beautiful lookin' truck!! congrats!!

Several posts on here where the kevlar bushing was suspected. I'd post links but they are spread all over OB. Maybe the suspicions were wrong, but just wanted to mention it.

Another way to I.D. the TOB, would be to get under there with the truck running, and collapse the slave cylinder to disengage the TOB from the presure plate fully. Sometimes what happens is they gum up, and the TOB actually starts slipping on the presure plate. With the presure on it though, their is enough friction on the presure plate to make the bearing roll through the gunk.

DeepRoots, what gears do you have?

Also, if you depress the clutch slightly at idle, does the sound go away? Many times putting a little preload on the throw out bearing will stop it's squealing. If it does, it's prolly on it's way out, although I've seen them go many, many miles like that. From what you posted, I'm guessing throw out, but pilot could be doing it too, usually they don't stop with clutch apply pressure though, at least that's been my experience. We had a guy that kept bringing a tb back from a new clutch set, I asked the clutch rep why they could be failing, he said a lot of people sit with their clutch depressed for redlights, etc. and it will wear them out much quicker than shifting to neutral.

You just answered one of my question without me asking it yet lol thanks! I guess i'll need a throw out bearing soon then.

Yup. Holding in the clutch is always a no-no. Didn't they teach you that in drivers ed? You should always slip it into neutral at lights and what not. After all, there could be a pedestrian crossing in front of you, and your foot might slip....

Yep, so true that's one thing my dad taught me when he showed how to drive Standard, when sitting at a red light or whatever, slip in Neutral. Besides it's a pain to hold that clutch anyway, stiff as hell. Most of the time I don't even use the clutch when I shift.
