Eric and Barry are both right, By just reading your post and noticed you crashed, or even before I read the part where you said you crashed, and mentioned you had a pull, I knew right away that you had something bent.
Check your spindles, your king pins, check your caster adjustment
A bad toe setting will not cause a pull, only negative caster or set back
loosen up your king pin bolts, spin the bolt from the top (head), if the spindle changes direction as you turn it, then you have bent king pins, replace them and check again.
It is very important that you buy a set of snipe lazer tool, or borrow one, that way you can be sure where your camber and toe is.
