RamCares, I'm new to Ram. I've had my 2020 Ram 1500 BigHorn a year. It has less than 16k miles on it. Recently I've noticed a rear end rattle that I can't quite pin down. Left rear shock feels like it could be loose but I'm not sure. I didn't find anything else out of place while under the truck. I tried to get an appointment at my local Ram dealer but the best they could offer was end of March.
