2015 Renny 1000– no front drain plug.

I just bought a used Renegade 1000 and I am doing basic maintenence

I watched YouTube and did the rear final drive but on the front I see the fill hole but no drain plug like the back.

Also, why do i see everyone calling the front are rear drives ‘Differentials’?

They cannot differentiate can they? They look like just basic drives correct?

Also I have 32 inch tires on this beast and I know I will be needing clutch/drive upgrades. Suggestions?
