I purchased my 2021 Gladiator Willys with 22k on it back in June. It has a slight loose clunk feel when coming to a stop, and when taking off. The best way to describe it is, it feels like axle wrap. Something that would normally be found in a leaf spring suspension. I have checked brake bolts, caliper bolts, bearing bolts, control arm bolts, and driveshafts. So far I have not found nothing. It does not happen all the time, but it should not happen any time. I hope you find your culprit.
