replaced everything....

This might be a dumb question, but when everything was replaced, was everything tightened with the car in the air? I know that the suspension will do some odd things if the bushings are pre-loaded, specifically the lower control arm bushings. Sorry if that's a little insulting, that is not the intention, just thinking out loud..and wouldn't want you to sell it over an alignment issue...
Also, what about the strut rod bushings?
