easier than expected, needed bearing knife, press with assorted pipes and such. I was able to purchase a factory lock nut tool for 4x4 but a modified dana 44 spindle nut socket filed down a bit would work just as good, if yours is a 4x2 its not needed. If you are just doing a bearing and seal rebuild its even easier.
Here is a good thread with videos and pics.
