Follow the instructions in the manual, although I found it easier with the front wheels turned opposite to what the manual says. I used a bungee cord to hold the wheel well liner out of the way. Easiest would be with the front wheels off. Highs are much easier to do than the lows. Overall not torturous.
Have done 2 methods on my 2017 wheelwell and housing removed from front, and on a 2019 thru wheelwells. Either takes about an hour first time and very near same amount of work, both ways could be done by a novice. Removing the housings is scarier. Dealig with exposed body work can be, but all parts have easy access and the bulbs/dust-covers will be on a bench. KM
