So i went over a speedbump today, very wide makeshift covering a construction line underneath, bottomed out and hit the bump (both front and back tires on pavement not ramp). Instantly smelled a burning smell. After work I drove it again, no burn smell. However, If I am on a decline(front end facing down) I can hear a rattle at idle. Is this my muffler being old and got shook up?
