A Body upper controll arm problem/question

$500 on a frame pull is not that much money if it fixes a good reliable car as opposed to buying a $500 car that would likely also need work.

If the car has been hit hard enough to drastically affect camber and caster then toe has been affecting also. You cannot adjust camber/caster without it affecting toe. Camber will affect tire wear, but generally won't eat tires fast. Caster has no affect on tire wear. Toe will cause all kinds of steering effort and drivability issues. Before buying any parts you should get the car on an alignment rack and found out what is going on.

You should see what the wheels on my valiant look like when they turn caster +5 camber-1. It goes down the road straight and easy.
