    whats your thought on this? TOB?

    My RPS stage 4 unsprung 6 puck has roughly 3000 miles on it? had the flywheel stepped and new TOB. had pretty noticable clutch chatter in nuetral, but fine in gear or clutch depressed. Never slips and im making 640lbs of trq. Now, i am wondering if my TOB is bad or if i need a new PP? if its chattering, and i press the clutch in a couple times in nuetral it will go away? wierd. With my tranny getting the new synchros and the tranny gone thru, was hoping to not have to mess with the clutch. flywheel has maybe 2000 miles since the last tranny episode. Atleast i am getting friggin mcgiever fast at dropping the friggin thing. lol

    Just not sure if its more of an anoyance or if this will hurt the clutch sooner than later.

    It's just an annoyance. My brand new TOB chatters too. Stab the clutch pedal and the noise is immediately gone. I've heard some people over the years blame that noise on the input shaft bearing of the transmission, but mine is brand new OEM (installed by Mitsu). Regardless, virtually every noise these cars make that goes away when you disengage the clutch is borderline normal, LOL, but definitely not tranny-dropping worthy.

    Depends on the day, but mine can get really annoying. Other days, not bad.

    my 92 chatters a little, but the trans in my 95 does not. The 95 also seems to have more bearing pre-load.

    If pressing the clutch lightly stops the sound, it's the tob. If you have to stop the input shaft from spinning, it could be loose springs in the disk, play in the disk to input shaft, a synchro rattling, or a transmission bearing.

    I would check for play in the hub of the clutch disc. Make sure those rivets are nice and tight on a solid hub disc.

    Ah yeah, good point regarding the depth of the pedal when the noise stops.

    A synchro rattling? Really??

    Mine didn't do it until I installed the solid hub clutch, same TOB. Usually quiet when trans cold and hear it chirping in neutral after driving for awhile. I had assumed some sort of gear rattle. But it does go away with a slight press on clutch pedal.
