Stop in for a cup of coffee
But toe is done last.
Ride ht, - > camber - > caster - > toe.
recheck camber after caster as those two are tighty related.
Alignment shouldn't cause a vibration. It should cause pull or tire wear, which eventually might cause cupping.
Strings are OK for toe.
Need a bubble gage or digital version for camber and caster... I assume you have that.
