I agree you can eye-ball it to drive it to get aligned.
now if you only took one side off then you can eye ball it pretty close.
to eye ball it you need to make sure the front of the car is up on jacks both sides
turn the steering wheel to straight and with the wheel off turn the knuckle
intill it looks like its straight with the frame of the car.
then turn the locking nut all the way out and away.
then turn the knuckle till its looks straight then hold the tie rod under the hole and keep turning it till it lines up with the hole.
insert and put the top nut on. put wheel back on but you only need one lug stand back and check if it pretty close. if it is then put the rest of the lugs on and turn the locking nut back to lock, insert the cotter pin and drive to align shop.
if its not keep doing it till it looks good.
but you def need to get alignment.
and dont do it again LOL
