The check strap bolts wasn't screwed in and tightened from the factory.They was backed out and clicking when you opened the door in the showroom.The dealership tightened them up and we took it home.Every few months they start backing out again.I put locktight on the bolts and it seems to be holding now.Just one more thing that come from the factory undone on this truck.I guess I bought one that was built the Friday before shutdown and everyone was more worried about getting out of the plant rather than building a quality vehicle.
