Earlier tonight I was riding next to a truck with my roof open, and thought I was hearing a squeak/jingle sound coming from him, but later found out it's me. I'm going in this week for an oil change so I'll have it looked at then, but in the meantime does anyone have any idea what this squeak (jingling?) could possibly be? Whatever it is, it's coming from the front left side, and happens between 30-40....
