Careful inspection of the oil you drain out may be helpful.
Changing the front differential oil will probably require removing the stiffening plate, along with the famous (or infamous) bolts. Set aside some time before delving into that topic.

Did the stiffening plate removal a few months ago for my front axle shafts and one of the best tips I've seen for dealing with this is to only remove THREE bolts and loosen the 4th one to allow the plate to pivot for access. Pick which way you need the clearance and then select the appropriate bolt to leave loosely fitted.
Worked great for me and yes, I reused the nuts and bolts and thousands of miles later, nothing has snapped apart on the freeway.
For front and rear diff fluid I use this
