Aisin Free-Wheeling Hub Install on a 80 Series Toyota Land Cruiser

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.
