Thanks to DieselDan for identifying precisely my problem, and I hope I can impose with a follow-up. I have a one-year old Adams trail-a-bike, which worked perfectly until recently the connection between the hitch and the trailercycle frame began to permit lateral movement (the trailacycle can move away from vertical even when the bike it's attached to remains vertical) causing excessive wobble, making the ride more dangerous and less fun. You mention an "updated, refined design" of a replacement part. How do I know whether a replacement part is updated? Thanks in advance (and hope you are still subscribing to this thread).
