Only time I ever ran into a hubcap squeak issue was when the Dodge dealer so over tightened the lug nuts on my MIL's Colt that my Impact gun would not remove them. They even managed to stretch the thread on the lugs and the nuts, all of them, on each corner. I suspect they flexed the rims too.

So I simply bent the springy fingers out more and no more squeaks.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
