step 3
ASSEMBLE THE SHORT OUTDRIVE HUB
Slide one #6573 washer onto the #6575 bolt.
Apply a generous amount of #6588 black grease to the washer
on the side facing away from the bolt head.
Place six #6574 balls into the grease against the #6575 bolt
and washer. Add the other #6573 washer. The grease will hold
the balls in place during assembly, sandwiched between the
washers. See figure for installed view.
Slide the thrust assembly into the #3912 short outdrive hub,
bearing careful not to lose any of the balls.
Insert the #6575 bolt cover.

ADJUST THE DIFF
As you tighten the diff bolt, you will notice the T-nut ears moving closer to the bottom of the diff hub slot. This compresses the spring
behind the T-nut. The spring should be fully compressed at the same time the T-nut reaches the end of the slot.
Caution:
Pay close
attention to feeling when the spring is full compressed.
Do not overtighten the bolt.
When you feel the spring fully compressed, loosen the diff bolt 1/8 to 1/4 of a turn. No more, no less. Your diff should now operate very
smoothly when turning the hubs in opposite directions. After you have driven the car once, recheck the diff adjustment. Never adjust
the diff any other way.
Now assemble the second diff the same way.
