If you can take front wheel off then getting the rest of it apart is easy.N4HHE ,I kept asking because it's out of my comfort zone . But if it's an hour for you to get apart I'll go for it even if it takes me all day. I have to figure out a way to secure the bike but not worried. I may as well try as losing faith in shops.
Driving the old races out of the chassis is pretty easy. Just don't bang on the aluminum lip backing the race. Each lip has 2 half moon notches to get at the race.
This is the view from underneath after bottom race has been removed.
Hardest thing is to get the bottom inner race off. Next hardest is to install new upper and lower races in the chassis. You might be able to do without but a race driver eliminates the possibility of a drift slipping to mar the race or your aluminum chassis.
Did a friend's 2018 with 4,000 miles a month or two ago. He had lots of doubt but no more.
