Transmission Noise

Noticed another noise recently when exiting the car. Rotational noise. In neutral with clutch pedal out: noise. In neutral with clutch pedal in: no noise. I suspect a dry throwout bearing. Car shifts without issue and plenty of remaining travel in the clutch.

I believe I know the answer but I have to ask. Any way to lubricate the throwout bearing without removing the transmission? Boxster S with 69,700 miles on original clutch.

If the problem is what you suspect... (analysis without visual inspection is not my strong point )
then you have to pull the transmission. It's just work, not rocket science. You might watch my video on YouTube to see how many times I pulled the transmission to discover my addle-brained mistake!

The throwout bearing isn't engaged with the clutch out. Your noise is probable the transmission input shaft turning, may be normal or could be a noisy bearing.

Thanks. You’re absolutely right. I had it backwards. Looks like I’ll be watching NewArt’s YouTube video ....

I've been having the same issue, I'm pretty sure it's the input bearing, as stated.
I just don't feel like dropping the trans yet, as I plan on doing a lot of work while it is (IMSB, RMS, clutch).
There's probably some other component (internal to the transmission) that would be good to replace while I'm in there, but I haven't done enough research.

Clutch-out-in-neutral noise is pretty indicative of input bearing noise, though.
