Separate iFixit guides cover the screen, battery and USB-C port; the battery and port procedures note different disassembly details for Wi-Fi and cellular hardware.
What to check before buying
Screen replacement
The screen guide says the fourth-generation 11-inch Pro uses the long-running 11-inch display connection layout, but replacement adhesive still needs checking. A panel quote should include the adhesive and any sensor transfer required by the chosen part.
Battery and USB-C
iFixit documents battery and USB-C port replacement for this generation. Its cellular-based procedure is only a general reference for Wi-Fi units, which may need additional disassembly; model variant matters when estimating labour.
