Ball Joint & Manual Hub Lock Parts
IF THE IMAGE IS TOO SMALL, click it.

This diagram shows a common manual hub lock.

Ford 8.8" axle uses 10 lug studs D6AZ-1107-A ('83-00)
Dana 44IFS uses 10 lug studs D6TZ-1107-A ('83-96)
Ford TIB axle uses 10 lug studs F4UZ-1107-A ('94-96)

Note that, to make the drawing easier, the axle tube (bright green) is shown inclined. But in actuality, it is perfectly horizontal, and the spindle (olive green) & outer stub shaft (red) are angled slightly down.

The axis of the ball joints (through the centers of the balls; not necessarily along their shafts) must pass through the center of the U-joint whenever the U-joint is rotating. That's why the location of the outer stub shaft (red) is critical, and the snap ring must be installed outboard of the spindle.
