'03 just turned 183,000 miles. Went up and back to Pigeon Forge, TN this past weekend. Had this noise (something like a playing card on the spokes of a bicycle) only a little louder and with some minor vibration. At first thought it was the rubber protectors on the muffler tabs (missing). Today installed protectors, still had the noise. Further examing led to possible driveshaft or maybe tranny. Run at 65 mph, have the noise; pull in the clutch, still have the noise; rev the engine, noise deceased as speed decreased. Honda says possibel bearing in tranny, has to look/listen to it. Two week back log in their shop. Anyone have any experiece with this kind of problem/noise? Thank you for any and all responses.
