    If ya don't know, I ain't tellin'
    Started up the 60 this morning after sitting a while and as soon as I disengaged the clutch (pushed pedal to the floor) it howled like a banshee--high pitched squealing. When I took my foot off the pedal, or even just let up a bit, the shrieking went away. When I pushed the pedal back down, it shrieked just as loud. Drove a few miles for an errand then parked it.

    I've had a low-level bearing noise for about a year (sometimes you barely heard it over engine idle) but today was ten times louder/higher.

    Is this pilot or throwout, and how soon does it gotta come out?  :dunno:  The "dead clutch" post has me worried.

    Thanks.

    In the end it doesn't matter, since you should replace them both along with the clutch disc and pressure plate. I've noticed in the past that marginal throw-out bearing will quiet down with my foot on the pedal. &nbsp:Don't forget to re-surface the flywheel.

    If it's the throwout, I'm less concerend about driving it for a few days. If it's the pilot, I'm gonna let it sit until it's fixed.

    This really pisses me off because my clutch is fine--but it's gotta come apart because a $12 part failed. Ah well.

    Thanks.

    first guess is throwout....and when it stops squealing, yer in trouble, cause it's siezed, and your expenses might include more than just bearing.

    IMO, order today, replace soon....mine has a "soft" squeal right now and is coming out this weekend.

    Loud squeal = last legs....and if it were mine, I'd park until replaced.

    It's the throwout.

    Pedal on the floor = t/o
    pedal up = pilot.
