I "thought" I heard a noise last week and today I definitely heard it.
Sounds expensive. Anyway, it's a knocking sound that happens around 40 mph
whether I am in 3rd or 4th gear. It does not make the sound (or not loud
enough for me to hear it) at lower speeds. Pressing my foot on the clutch
makes the sound stop and I coast quietly along.

Thoughts? Insight? Laughter?

Thanks,
Bryan
