What is the best way to align the fron end at home? The lasy time I did it I took off the wheels and clamped 4' levels to the brake rotors. I continued to measure in front of and behind the rotor until I got the same number and then toed it in just a hair. The hassle was knocking out the rod end. Do I need to or is the coupling rod made with a right and left hand thread? Also the reason I am having to do this again is that one wheel fell out of adjustment when I cranked the wheel hard one way and heard a pop. When I looked one of the wheels was badly toed out. Is it possible I stripped the threads in one of the couplings?
