Jerry: I would not characterize it quite like that, here is what I can tell you with 100% certainty…
1) the cap never came loose, it is the bed itself that moved, NOT the cap.
The dealer reset the bed and tightened it down but they were unable to tell me WHY it had moved… torque not to spec? Forgot loctite? My imagination runs wild but dealer was unable to say exactly why it moved they simply confirmed that it had.
2) I know the exact day that it occurred, the “bumpiest” thing I drove on that day was my in-laws driveway. It’s gravel and a little rutted but I’d consider it normal use. My wife’s Impreza made it just fine. No sudden stops or evasive maneuvers, although sudden use of the brakes wouldn’t excuse the bed coming loose.
I will try and post a pic of the cap o have, it’s pretty standard.
You are right in part though, it’s undisputed that the bed moved but nobody has been able to tell me why to my satisfaction.
Edited to add the model and pic. It’s an ARE Overland model.
