Need Help Rigging a Landing Gear

[Aelno]

So I'm learning how to rig in Maya and I just can't get this landing gear to work. Can anyone show me how to rig this in Maya to animate properly? I've attached the full project file with these objects. I avoided adding too much detail to the objects since I may need to make changes. There is also a Skydome Light in the scene, but you'll have to insert your own HDRI or light source as the file was too big to add.
