Anyone experiencing a rear clunk when in reverse and at low speeds? At first I figured it's normal for a empty HD truck but the more I search I more I feel like that's not the issue. There is a thread regarding a similar issue on the 1500's: https://www.gm-trucks.com/forums/topic/236724-slow-speed-suspension-clunking/
Thinking about bringing it in for a look but not sure if it's normal.
