differentials, oil, covers, and questions

I figured I would show some pictures of my work this weekend.
I pulled off the differential covers and found a LOT of water and some gooooo that used to be differential fluid.

My questions are this.

I have a 1976 CJ-5 with a AMC20 rear and a D30 front.

I know water is bad in there, but what am I looking for when I take this apart to see if it is bad? It is my first time taking apart differentials on a 25+ year old machine. My 2001 Dodge Ram 1500 looked nothing like this.

Secondly, I am figuring this is unlocked from what I see in the pictures, but let me know if I am wrong.

Thirdly, I need to find out what gears I have in there. I am not sure if they have ever been replaced.

Front

Rear

And lastly, my humor for the day. You have to stay positive when you are sinking tons of money into your love.

Thanks for the info.

the first pic looks like it had water in it for shore the second looked like it had some water but not as much gears the tag on the rear should have 2 sets of numbers like 9-41 = 4.55 or jack up the rear mark the drive shaft turn the drive shaft till it goes 1 turn and see how many times the tire goes to the drive shaft = 1 drive shaft 3.5 tire turns

Another way to tell the gear ratio is to look at the stamp on the ring gear. It is on the side and will have the tooth counts of both the ring and pinion on it. Divide the ring gear tooth count by the pinion and you have the gear ratio. Should be pretty easy since you already have the cover off.

Well the cover is back on now so that is going to be a little hard. I guess I can do the jack up the rear end test and see now many turns the wheel does test as mentioned before.

Thanks!
