Well, I've been struggling to get my caster back up in the +3s for the last 2 months. I'm happy to report, after 10, yes 10 alignments and a couple control arm brands later and new cam bolts... JBA off-road high caster control arms were the answer! First time I've seen my alignment this good in years. See photos (look at BOTH of the "afters" to see caster)... So if you've been struggling to get your caster back up to spec this is your ticket!!! Just fyi for the 4Runner you will prolly have to ever so carefully hammer the thin washers in on one side, no other way.
