technically yes, but guys are trying to mark it before & hopefully not have to. personaly, after doing my own alignment I can tell you that even the slightest movement of these bolts are going to affect alignment & theres really no way your going to be able to maintain an exact alignment with the just marking it technique, especially considering that when it was adjusted the suspension was under load while being aligned & you just can't get the exact same acurate alignment by just marking the same spot, although it should still be kinda close really I guess......
