Hi there. Thank you for sharing your experience with us. We understand that your LG dryer model DLGX4001W is rattling during use or even when bumped. Your feedback is important, and we'd like to assist you further. A potential troubleshooting step you could try is to ensure that the dryer is properly leveled. Sometimes, uneven flooring can cause the machine to rattle. Additionally, check that all screws and bolts are tightened, as loose parts can also cause rattling noises.
