How do you change the hub on a Toyota T100?

I have a 97 T100 4wd. If it is a 2wd the front hub should be just like any other hub-remove the axle nut. The rear shaft and hub has a retainer on the axle on both 2wd and 4wd. On the front of the 4wd there is a cap screw in the end of the drive shaft and the hub is splined on the shaft-unscrew the bold and the hub should come off.
