Last four trips out the ride starts quiet than about 15 miles in or so I get a popping/snapping noise from the rear. Gets more frequent as the ride goes. Side to side motion causing it not up and down. Let it sit and the next day can’t get it to do it sitting in the driveway. Next ride, same thing. Finally decided to see what the techs could figure it out and they can’t get it to make the noise of course. They said they checked everything and it looked fine. My first thought was the bushings. If they are bad, they are bad and wouldn’t just stop and start doing it, right? Is anyone else having this issue? Maybe related to the heat shield? I can hear the noise but best guess is up under the rear seat. Just went over 2000 miles and greased regularly.
