17. Use a ratchet or breaker bar and a 1 ¼” deep wall socket to turn the flange half threaded bearing cup in until the
ring gear contacts the pinion (zero backlash). Back the cup out two notches of the adjustment plate.
18. Turn the plain half adjuster ring until there is zero preload on the bearings. This is done by turning the adjuster
plate clockwise until you feel the threaded cup gain resistance. The threaded bearing cup should only be slightly
snugged to achieve a zero preload condition.
19. Obtain two notches of preload by tightening the plain half adjustment plate two notches. Start with the notch at the
top, count two notches counter-clockwise on the adjuster plate. Turn the adjuster plate so that the notch is facing
straight up.
