Door latch/actuator assembly --- WEEEEEEEEEEEEEEEEE... Those are fun to do, especially the rears, you gots to release the window glass from the lift plate, 1 tech has broke the glass a couple time before figuring out how to release the glass.
Then you got to take the door handle off outside of door so you can swap plastic cover and link assembly, and switch the cable.
Fronts is a wee bit easier to do
