like many others I had a rear hubcap fall off on my last cross country trip discovered the problem is the rivets were broken on Spring loaded holding clips.
six out of 12 rivets were broken and missing I can’t believe it stayed on at all
A 3/16 drill bit and a 3/16 short pop rivet repaired the problem they fit on nice and tight I don’t think they’ll fall off
drill out the old rivet location with the 3/16 bit being careful not to drill all the way through the hubcap take a screwdriver and pry the holding clip up insert pop rivet and pull it tight until the pop rivet breaks off
I would recommend pulling off your hubcaps on the rear and making sure none of the rivets are missing on the holding clips if you want to keep your hub caps
much cheaper to be proactive and repair them replace at $150 each
only the rear hubcaps were broken the front seem to be fine
