1 - The reservoir in the picture below...is it a brake fluid reservoir? I know the one behind it to the right is the master cylinder but what's the other one??
2 - Should I be concerned with the other picture, front diff?, Not wet or dripping but......?
The one your arrow is pointing at is the brake master cylinder, the smaller one behind it is for the clutch.
On the diff, you have a seal going bad. Nothing new under the sun there. Check the fluid level, make sure it's up to snuff, fix it when it's warmer outside.
Pinion seal.
Is it hard? Look in your manual and youtube to see what's involved.
Most auto parts stores have the puller you'd need as part of their loaner program.
