Removing front hub grease caps

[jey@frame.com (Jeff Young)]

The threads don't actually matter much, since the grease cap is
less than 2 threads thick.  I've used everything from bolts to
wood screws.  Anything handy that fits in the hole without too
much room to spare.

The pounding w/ screwdriver does work, but it bangs them up pretty
good and can be quite frustrating.
