breaking loose the outer ball joint is the hardest part of this job
these easiest solution i've found is to...
go to autozone and rent out their tie-rod end puller, it's a small puller type press, it just happens to fit almost perfectly and allows you to push the outer ball joint out of the hub,
here's a picture of what you should pick up
using it on the car is pretty self-explanatory
but if you need further guidance, just let me know
