My husband took it out for a ride...said it's a little bumpy at 30-40, but on the highway at 50-ish it smoothes out. We'll still have it checked out. Funny it didn't start doing something like this right off. I had about 110 miles on it before this happened. Belleville is convenient for me. TonyG, I messaged a couple of times but maybe didn't go through? Still figuring this site out!
