How much is an MP3 supposed to be able to lean when the tilt lock is on? While I was out on my road trip, at one time, I stopped and locked the front wheels together, like I always do. Before I got off, though, it started leaning to one side. I quickly put my feet down because it felt like it was going to fall over. After a few degrees of movement, it stopped. Ever since then, it's done the same thing. Even when locked, it will move a little. It doesn't seem like it's enough to cause problems, but I don't remember it doing this before...
