i have done pretty extensive research on this, the only thing i can find different than front end alignment is camber issues? my car gets a groan/shudder, not a whine or squeal and not a vibration but a shudder. and it happens when i cut the wheel in either direction ALL the way and everyone feels it inside and out. if i could accurately break up the turns id say its the last 1/4 turn before it wont turn anymore. normally you just here the pump or something give a tiny little moan cuz the wheels are cut all the way. everything is balanced and aligned.

any ideas or suggestions? what could this be?
