I'm a newbie here and need help with an old problem. My 03 Extra cab has started pulling badly to the right. I had the front end aligned and they told me the alignment was spot on when they finished it up. Tires are properly inflated etc. My question comes up now as a result of putting it in 4 wheel high and noticing the truck feeling very stiff at next to no speed and it wants to lurch and grab. Just did a brake rebuild rotors, calipers, pads and all associated parts , so i know it's not a stuck piston ... Could this be in the CV joints ... HELP !!!
