Upper A-arm bolt

["Daniel Beatty" <nowroc@pacifier.com>]

My upper A-arm bolt that acts as the pivot point for the arm has a great
deal of up and down mobility within in the hole.  How easy is this bolt to
replace?  Is it merely releasing the pressure on the suspension by dropping
the lower A-arm and spring, then replacing the bolt?  My concern is that the
hole has been misshapen.  Is this possible or does the bolt have a bushing
that it is riding on that has just deteriorated?

Thanks,
