We discovered that my Land Cruiser had a part time transfer case so I decided to install Aisin Free-Wheeling Hubs. Besides looking cool, the manual hubs allow the front axle to be disconnected from the drive train, theoretically saving fuel and wear and tear. Note from my understanding the Aisin hubs can be installed on 91-93 80 series Land Cruisers with the shorter birfields. Also when you remove the hub face from hub body, note position so you can put it back together the same way. Some people will mark position on body when they remove hub face.
Here is a shot pre-installation. First step is to remove Toyota plastic hub cap.
Shot with hub cap removed
Hub Cap Removed
Next remove nuts and washers holding flange
Set nuts and washers aside since you will be reusing these
Small metal cap needs to be removed with a screwdriver.
With cap removed you can access snap ring which comes off next.
Snap ring pliers make easy work of removing ring

Remove cone washers. Easiest to tap outer edge of flange with metal mallet to pop them out (See below video)

Clean surface with cleaner (Simple Green) and install new gasket
Install Hub body and reinstall conewashersNote:when you remove hub face note position that it sat in the hub body.
Reinstall washer then nut over cone washer.
Reinstall snap ring making sure it is in notch. I used snap ring pliers to get this back on.

Install hub face on body making sure it is in “free” position and put back in same position as when it was removed.
