Disk Brake Conversion question

I'm an old, haven't done it since 1972 ,front end mech. If it is the calipers, rims won't seat on the hub. If the calipers don't rub, it is something loose/moved, in the front end.Like the adjustments bolts/nuts were not tight enough. The brakes can't cause that. Check wheel bearings, bushings, idler, ball joints, and especially- upper control arm bushings, and location.
