When you receive the axle:

Make sure to grease up the axle set. You can fill up the empty space with diff grease surrounding the bevel gear and input shaft.

The gear positions are factory setup and should be ready to go. Rotate the drivetrain by hand for physical inspection.

Install spacers accordingly between the center driveshaft and the input shaft to prevent input shaft from unnecessary slop.
