2015 Tacoma Pre-Runner (2x4) differential and transfer oil change

Help please! I have searched threads and am easily confused. I understand how to change my rear differential gear oil. My question is is there a transfer case on a 2x4? Also is there a differential on the front that oil needs to be changed? All the pictures and videos I have seen don't look anything like mine as far as the front differential. Sorry guys for being a rookie. I am trying to save money and I just bought the truck with 50k miles and it's never been done.

 

Only 4x4's have a front diff and a transfer case.

 

Thank you so much, it has been driving me crazy. I couldn’t find that answer anywhere.

 

Of course...I've learned a lot here, so I try to help when I can.
