I posted this on the forum #3 but realized that not everyone looks there. So here it is:
My D Rapide has developed a noise that I think is coming from the gearbox. It's a rather quite whine (or maybe I should call it a hum). The noise is only present when power is applied. Back off the throttle and it stops. It's road-speed related. Changing gears does not change the pitch. Rev up the engine in neutral or with the clutch in and there's no noise. The pitch does seem to go up with speed, but that's hard to discern. I haven't done a high-speed test. The fastest I've run it recently was maybe 55 or 60 mph. But the noise is audible at 30.
So am I right to suspect the output bearing in the gearbox? Winter is coming, so I suppose it'll give me something to do; as if I needed that!
