Truck is running rough I let the clutch out and it starts making a rattling noise

Hello, it could be a concern with the transmission, the clutch, the flywheel, an engine performance issue or some other concern I can't imagine since I can't hear the noise or see the problem in action. The noise could be an exhaust heat shield - but there could still be other problems present with engine performance causing rough running.
