Went on long ride today and my trike started making weird noises, mostly when coasting like downgrade. More miles in started getting some vibration felt clear up into the handlebars. Decided I had better get this checked out, detoured off route and went to a buddy house where we could check it out. Suspected the driveshaft first but it appears to be fine. Put the rear end up on blocks with both rear tires off the ground and when you spin either side it sounds like rocks in a washing machine! Damn this is not good! Trike has right at 8100 miles on it. Now I'm gonna loose it during peak riding season and we had a 4 day ride coming up fathers day weekend with hotels booked! I'm not happy! Calling dealer in the morning to see what can be done with it.
