What is the proper way to change the lowewr unit oil? Do I just use the 90w gear oil? Thanks

Pump oil into the lower (drain) hole till it comes out the upper (vent) hole. Replace upper plug before removing filler from lower one. Then quickly replace the lower plug. DO NOT remove the phillips head screw!!!!

Yes, 90 weight gear oil. Or 80-90.
