Hi everyone,
I would like to introduce myself to this group. I am an aeronautical engineer,
pilot, airplane homebuilder and writer. I have written 3 books for airplane homebuilders,
which you can check out on my web page www.caroengineering.com. They
are mainly for airplane homebuilders, but should be of interest to anyone who
wants to install engines, work with composites or flight test an airplane.
Take a look.

I don't know whether your aileron hinge bearings are similar to the ones on
my RV-9A or not. In any case, a common shop trick to remove/replace
bearings in place is to use a socket or bushing that is smaller than the
bracket ID on one side and a socket large enough to clear the bearing on the
other side and a bolt or piece of threaded rod will work as a press for
removal. Reverse the process for installation. If the replacement bearing
is a uniball type as mine is, be careful that the bushing/socket only
presses against the outer rim so as not to damage the bearing itself. The
same caution would apply to ball or roller bearing replacement by this
method. Hope this helps.

Dean,
I got out my high powered bifocals and cleaned up the bearing to take a
look. The hinge bracket coming off the wing is two pieces sandwiched and
riveted together. They are counter bored for the bearing to nest in. The
counter bores (each side) are too big in diameter and too deep. From what I
can tell the bearing is not pressed in or staked in from one side or the
other. It looks like the pieces were counter bored and the bearing
installed between them, then they were riveted together. I don't believe
that the bearing can be removed without drilling out the rivets and
separating the two pieces.
