Use this guide to replace the upper case of the 2018 MacBook Air, including the keyboard. This involves removing all the parts in the MacBook and transferring them to a new upper case. Make sure to keep track of screws and small parts so that they can be easily reinstalled in the new upper case.
Due to overlapping prerequisite guides, there are some repeated steps and inconsistencies in the photos. These are expected and do not effect the procedure. If you notice a repeated step, skip it and continue with the procedure.
To minimize risk of damage, turn on your MacBook and allow the battery to fully discharge before starting this procedure. A charged lithium-ion battery can be very dangerous if accidentally punctured. If your battery looks puffy or swollen, take extra precautions.
Do not reuse the battery if it is swollen or was deformed in any way during the procedure. The battery is likely damaged and can be very dangerous to reuse—it should be replaced.
This guide involves removing the speakers and battery. You will need new adhesive to reinstall the speakers and battery.

I will be tackling this repair soon for my MacBook Air… I see I will need new adhesive to reattach the battery and speakers. What kind of adhesive should I use, and where can I get it?
I just repaired mine, if you buy the whole upper case part, it already comes with adhesive for the battery. The speakers were still tacky enough to hold mine down. Don't forget to take off those hex nuts off the old upper body because the new part won't have them. I believe it is about 6 of them
