2018 Outback - front axle - alignment ?

[craigmcd]

I recently had a whole super negative experience when DIY replacing the REAR hubs and CV axles on this 2018 Outback. The electronic parking break needed to be reset by the dealer and other issues. It was costly. As a result, I am a little gun shy to replace the front axles on this Outback.

Q1 - is it advisable to get an alignment after an axle replacement? 

Q2 - is there anything which needs to be turned on, shut off, reset or otherwise completed with an OBD2 scanner when replacing the front axles? I have a decent scanner.

Q3 - I have done front axles before on Subarus, but is there anything I should be preparing for or anticipating before I start with the nuts and bolts ? (insert your sage advice here)

Thanks,

Craig
