when in neutral and i let the clutch peddle up i hear a grinding noise but when clutch peddle down i dont the noise any more what ya think it is

 

throw out bearing or pilot bearing

 

I'll second that one. If it starts squealing, get home fast. It won't be long before it won't shift at all.

 

Not really, mines has been making noise for almost a year now and I'm currently fine, I'm pretty confident that its the Throw-out bearing and I have exactly the same symptoms as you have. Personnaly, I'm gonna ride it till it bust!

Here is a nice little page of tranny trouble shooting (also the only one on the web I have found so far).

Output Shaft Bearing?
~Tom

 

Input shaft bearing. I have that noise too, lot's of people here told me I'd be due for a rebuild by now, but it hasn't gotten any worse and there are no driveability issues with it. I can barely hear it unless the windows are up and the radio is off and the car isn't moving. I've noticed the noise in 2 other FD's and both of their owners said it seemed normal to them. I asked George from Sevenspeed (who did my 5 speed conversion) and he said it was fairly common to hear it on FD's and that unless it got worse not to worry about it.
