As a DIY project my suggestions are to refer to the writeup at http://www.outdoorwire.com/4x4/isuzu/. Also, make sure you don't lose the shims. They tend to stick to the hub, at least on my 1999 Trooper, until you go looking for them. In addition make sure you have the proper allen wrenches for the job. I also did not pound off the hub bolts as suggested. Instead I added a piece of pipe to my metric allen wrench for extra leverage. This seemed a better approach to me but then again like I said I am no mechanic.
For what it is worth, I probably would have purchased the premium Warn hubs had I know they were available at the time. However, since doing the install and reading about the pros and cons of premium Warn (not the basic level product) and Superwinch I think I would stay with Superwinches as they seem to be just as reliable and cheaper. Seemingly the hardcore offroaders would go with rebuilt AISIN hubs due to their supposed superior strength.
Depending on your mileage, you may also want to grease your front wheel bearing as part of the hub job as your will be 1/2 way there.
