The thing about the uppers on dual A arm GM vehicles is they are just a follower and not a weight supporting joint. That is why if greased they should last and last. However on the lowers some slight play is ok as the load takes all the lash to zero ( except on severe washboard road surfaces). The uppers need to be tight as they do not benefit from the zeroing of the loading. If they rock under acceleration, braking or steering the caster, camber and to some lesser degree toe will keep changing.
