How long depends.
On your speed and tools and 2-4W.
2.5 to 5.5 hrs book flat rate time.
First time I would figure a good day on it.
Use good quality parts for a good long lasting job.
Good luck and watch that hammer and do not hit/mash your fingers.

2WD and 4WD are totally different when it comes to ball joint replacement.
