What is More Likely to Go Out, the Flywheel or T.O. Bearing?
I have been noticing a noise coming from my clutch at idle. It goes away when I push the clutch in and again, only happens at idle. It's almost like a knocking, sound, rather than the usual grinding sound that throwout bearing make, which leads me to believe it's the flywheel, being dual mass and all. Any ideas? Anyone have this before? I'll try to get a video of it up tomorrow if I have time.
Could be an input bearing going bad. When the clutch pedal is pushed down, engaging the clutch, the input shaft of the transmission stops spinning (or slows down a lot, perhaps not a total stop due to drag).
So, the trans would need to come out anyway. I'd check the fluid level, even if you don't see any leaks or drips, and make sure it's topped off.
If the noise persists, you'll have to bite the bullet and get it fixed sooner rather than later. If it is the bearing, and it spins, you're looking at a trans replacement instead of just a bearing.
^ This. Just went though the exact same symptoms with my buddies 05' OR and it was the front output shaft bearing.
FWIW, Flywheels are usually pretty stout, unless you get some crazy high-perf pressure plate slamming against it, they often stand up to tons of use... an occasional shipped tooth on the starter ring is about the only "common" problem with them in general, and when this is the case you'll notice most when starting the vehicle.
