With rusted threads, use a good dose of "PB Blaster" and let set over night. it should come out easily the next day.

If you are turning the wrench and it does not unscrew, this may be what you
have.

If you have to drill to get the old one out try a left hand drill bit. Often
the left hand rotation of the drill bit loosens the thread and unscrews it.
I have never had much luck with EZ-outs if the threads are rusted.

IMHO, use an EZ-out, inexpensive and work. I've never seen a Zerk that
was
not tapped but surely could exist. Mine are tapped. Even if you have to
end
up drilling it out you can rethread. Just keep the drill size of the EZ-
Out
doesn't work less that the tap size specified for the Zerk thread. Be
sure
to THROUGHLY flush out the fitting hole, don't want any chips or crud
getting into the bearing. You can't put to much grease in, you should
see it
oozing out before stopping the greasing.

Good information everybody.  And quick too!  Thank you.

One more question.  Removing the remains of the Zeck fitting, would
anybody know if this is tapped or pressed?

the bearing, the Zerk fitting broke when I was removing the grease

Does anybody have an idea of what I should replace it with?  I got
crickets from US Tower.
