if you have ripped into your front suspension any time recently then it wont be that hard....took me about 45 minutes to completely change out the axle....I have had the hole front apart due to the swap so all the bolts were still very easy to undo and I knew exactly what I was doing, so I suspect with a few tough bolts prob around 2 hours especially if the hub bolt hasnt been undone in quite some time. (my cv boot ripped 2 days after I finished my swap...go figure....)
