915 Roar - TOB vs R&P

[RarlyL8]

I have very little experience with the innerds of a manual transmission and need some assistance.

What does a faulty Throw Out Bearing look and sound like?

How does this sound differ from a faulty R&P?

Would a faulty R&P noise increase with vehicle speed while a faulty TOB noise would increase with RPMs?

Thanks.

A bad ring and pinion would generally whine. The pitch will get higher as road speed increases and the amplitude (loudness) will vary a little with increased load. Other things can make these noises too (bearings, for example.)

A throw out bearing, or pilot bearing, should make noise when the clutch is disengaged.
