Do the normal testing on inner pivots. If they are at all loose, it's easier to replace the control arm complete if you have a means of getting the alignment close enough to drive to an alignment shop. Otherwise, replacing the inner bushings requires making a tool, they are swaged in place and can be a pain.
I've not replaced any of mine, even at 400k miles. Ball joints usually last 200k or so, give or take a bit, but that depends on driving conditions and the presence or absence of road salt. You will need a good, not a cheap, ball joint tool. The cheap one will bend.....
