My low 5.83s that I got from Heather were
set to .008" by Trail Tough, so the ring gear
(crown) should move .008-.010" with a dial
indicator set up touching the ring gear teeth
The most important setting is the pinion depth,
but if you didn't change gears and just installed
the locker, adjust the back lash to meet the 8-10
and you should be good.
