If the c bushings are in wrong will this make truck road walk all over the road? If not what do I need to look at? I have new steering gear & hiem joint steering linkage that has no slack. Please let me know, I can't drive it like it is. .

Yes, caster is the #1 cause for a poor handling Bronco. The C bushing could be in wrong, or could not be providing enough caster correction for the suspension lift, if present. An alignment shop should be able to tell you your current caster reading, a good # is between +4 - +9 degrees of positive caster.
