This is kinda strange but twice now, on different rims, ive had the center cap either fall off or they have been stolen. I replaced the first one and putting it on I feel like they are in there plenty tight enough to keep them from just popping off. Has anyone else had this happen? Ive got the second one coming from just4jeeps.com so now ive got 50 bucks wrapped up in these caps. thinking about putting some megaloc on them just to be safe.
