Default which bearing is it and am i fucked?

installed a clutchnet red 2x pp and organic disk two weeks ago. New pilot and throw-out bearing. I thought I was extremely careful but apparently not enough. Today it was nice out so I had the windows down on the way home. There's a continuous cricket-like sound when driving that goes away if I put even the slightest pressure on the clutch pedal. Which bearing is it? I'd imagine the throw-out but I'm not sure. Am I fucked? ie. do I have to drop the transmission again to replace the bearing? What could I have done wrong to make it make this sound? There's nothing to drift home, it just replaced the old one. I don't see how I could have fucked it up. What gives???

the slave cylinder rod needs to be greased where it meets the release fork.

not the TOB. search m.net for "clutch" "noise" "gear lash" you'll come up with thousands of posts where people swap the clutch and have weird noises.

i did put a dab on when i changed the clucth but the slave is leaking and may have washed it away. I have a new one I'm putting on tomorrow. What about changing the engagement point on the clutch? When first installed the clutch engaged close to the floor and I've since spun that little rod under the pedal to bring it back up to the stock engagement point. I did read that if it is not adjusted correctly there can be too much pressure on the bearing. I'll try the slave first and see what happens. The only other thing that leads me to thinking it's the throw out is that I still hear the sound at a stop light with the car in neutral, it's just slower sounding. I'm happy to hear it's probably nothing major. I almost cried when I heard it, no joke.

I have the same noise with mine, although nothing is leaking. Still haven't had a chance to get under there and try greasing it up or adjusting the engagement point (mine is close to the floor at the moment). If you find something that works, be sure to post back up!

Mine did that (the OEM one), but it went away after the new clutch install.

it is very possible that it's a throwout bearing, if you don't find an easy fix, pull tranny and put your old TOB back in

so I changed the slave and greased the **** out of the rod end and where it contacts the fork. No more noise! On a side note bleed your clutch if your shifting is notchy. Mine is much improved, as well as the clutch feel.

I had the same problem when I bought the car. I put a new slave in and it was fixed. Seems to be a common deal on Miatas.

Glad you got it!

Since my slave isn't leaking, I'm going to go out and grease the hell out of the piston end and see if that takes care of it. Thanks for reporting back!
