What if any synthetic fluids did 2010 RAMs come with from the factory?

front diff, rear diff, transfer case, power steering, and transmission are all synthetic fluids from factory.

motor oil is not.

All coolant is Ethelyne Glycol based, which is synthetic.

is the front differential synthetic for sure? the reason I ask ia my maintenance chart doesn't call for synthetic but the rear does. I have a 2010 with 75000m that I feel more drag then I think is normal on when I'm in 4x4 so I bought some penzoil synthetic gear oil to do a change with when the weather gets better. Being 4 years old who knows what the last owner used if it's even been changed at all.
