Thanks for your input. How about practically speaking? These altimas do not have an upper ball joint. How much does changing a lower ball joint really effect camber, caster, and toe? All things being equal - the ball joint is attached to the knuckle the exact same way the old one was, and I used the same control arm. The old one was very shot (20 years old) and was flopping in the breeze. Interestingly, it was still functional though.
