takeing off at low speeds, a low vibrating sound, almost like a growl.
occasional popping sounds eventually stopped on their own.
separation of heat shield from muffler at on end causes rattling at certain low rpm. get it tack wielded or metal straps put around to secure heat shield and rattle will cease.
when start driving in a very low speed then sounds was generated underneath the vehicle. seems like the exhaust piping area. can't even duplicated even you try to bring up the truck and tried to duplicate the sound but nothing will found. looking forward to have information on this on hoiw to resolved.
Most noticable at slower speed over rough roads e.g. speed bumps. Very sensitive will rattle over any small bump

Heat shield rattles at low speeds, the fix from the dealer made it worse
Heat shield on muffler is tearing loose on one end. At low speeds it makes rattling noise.
