At the dealership now dropping it off. The service manager’s 19 is in shop for same issue as well as another customer. They’ve had Star cases open on theirs. Tech said he didn’t need to ride with me to feel the clunk because they know it exists now that I’m not the only one complaining. Guys, please go in and get it checked. And as I’m typing this, manager walks up and says his is fixed. They bought “body ears” to attach all under truck and drove it. It relays to a hand held screen. He said it found nothing so they went under his truck and tightened every single thing they could and it’s fixed. He admitted they tightened so much that they aren’t sure what was loose. I’ve had my body mounts tightened already, so that’s not it on mine. He’s all smiles and he swears mine will be fixed even if they just have to tighten every single thing. But the Star cases are open on those other two trucks so hopefully that helps everyone.
