New project

I am about to take the diffs apart and and look at them for fun to learn more about them and was wondering...what fluid do you recommend to put back in...and I was also thinking about cleaning up the diff covers as well and re paint them...(no chrome)...I hear atf4 and mercon 5 alot so I figured it was safe to ask for opinions.

Not in the diffs. You use gear oil in the diffs. It tells you the recommended oil in the manual. Something like 75-90 in the front and 75-140 in the rear.

No problem, you were probably thinking the Transfer Case. You use ATF+4 in the transfer case.

I am not understanding your comment or humor...is 85-90 good or synthetic.
On a serious note...I have now noticed that the bleeder from the rear diff is always leaking...I have asked and was told I am either too full or not enough in it and it is foaming up...that is the main reason that I am taking it apart to see what is going on. Tips on what not to do and what to do is helpful. Can't be too hard...remove bolts and clean off old gasket material and re caulk it black rtv and bolt it back up and fill it to the fill plug...right???

I'am a "CHEEP B@$T@RD" & straight 85-90 is a few $$$ less than the synthetic...

I filled it up to the fill plug, but the manual states to go a 1/4 below I think. I just filled it all the way up because I plan on draining it and putting synthetic in this summer.

Buy the black RTV with the name "right stuff" This way you can fill up the diff about 1/4" below the bung hole after waiting about 15- 20 minutes. First take the all of the bolts off leaving the very top bolt loose but attached to drain. A putty knife works to seperate the cover.
