I've got a new bottle of Gorilla Glue, will give it a try

Tanx

take a punch and put four punch makes on the part that goes into the hub. Mine did the same thing, one even came off and hit the grill on my buddies truck that was behind me.....

Marine tex them on....

They become kinda useless if not removed and installed correctly. To remove, they need to be walked off slowly and evenly. In other words, tap lightly working around the outside SLOWLY and evenly working it off. If you hammer it hard on one side, then the other, that oblong and distorts the press area making it prone to come off easy when reinstalled. (It will not go back to new shape when reinstalled, once bent, always bent) When reinstalling, try to tap it on evenly working around the circum. Again, if you cock it back and forth, it becomes distorted and losses the press.

Slowly and evenly, both on and off.

getting off is far too easy, thanks all, will try both dimples and some goop (and less grease)
