I drove the wifes wagon today since she said it felt weird and when I start to brake it pulls sharpley to the right. I also noticed on the highway when I push the gas pedal it pulls a bit to the left and when I let go of the pedal it goes back to the right. I'm planning on doing ball joints, the right side tie-rod and the rear struts. Is there anything else you guys can think of.

 

Maybe the left side caliper is broken.

 

I'd check the bushings too.

 

if I brake hard its less noticable but I noticed today that the left rotor has no screws in it would this make a big difference.

 

sounds like your left front caliper maybe getting stuck (theres a pin in there and if the system gets old or isn't maintained [flushing brake fluid]...it will cause the caliper piston to stick and not go fully back...this causes the pad to drag on the left rotor making it track left when not braking and causing it to pull right when braking since the right side is getting much better brake contact b/c the pad isn't worn as much as the left one

 

Pulling right under braking and left on acceleration sounds like a suspension problem to me. Ball joints, shocks/struts, and bushings.
