My ‘19 SLT is doing the same, as another user on here described sounds like “ a bowling ball rolling around the bed”. Looks like this issue is more wide spread than I thought.
2019 SLT 5.3 same thing. Clicks and clicks till the cows come home, regardless of the engine temperature. It’s really noticeable when I remote start the truck in the garage before I head out. The sound is amplified and as someone above mentioned makes it sound like a junker! I’m curious if anyone here has taken the truck in for this reason? I’m close to doing it just in case.
