I don't mean to disagree with Mr Harris, but I would do the ball joint flip now because you are going to get new tires. I lifted, but didn't flip the bj's originally - I did get an alignment right away tho. The wear on my tires after that was my indicator that I needed to flip the bj's - pretty expensive way to figure it out the alignment didn't take. Also, I went to Firestone and got the lifetime alignment deal that Tone mentioned awhile ago. That way I can keep an eye on things before I wear out my $200+ tires, and when I get HD tie rods I will get a free alignment, and when I get new shocks I will get a free alignment, and when I re-lift I will get another free alignment. I think it cost $160 or so.
