While trying to retrieve a deer from a bean field this fall, I found out the hard way that the 4wd on my '74 fj40 was not working. After digging it out, I checked to see if the front drive shaft was turning. It was so I am guessing that it is a problem with hubs. I am getting ready to go through all of the brakes, and want to take care of this while I have it apart. So I am want ting to know if anyone has any Ideas. Should I just go ahead and replace the hubs, or is my problem somewhere else? Any advice would be greatly appreciated.
