Should I Change this Diff Fluid?

So opened my diff plug and this ugly mess came out. I have the D35.

Looks like water got it in or something... i would change it deff..

One way to know if your diff fluid needs changed is to put some on your finger, let the excess drip off and then count to like 10 seconds if it doesnt drip its still good. But that mess looks nasty. Btw why didnt you use a pan to catch all that ? Or was it coming out of the fill plug ?

RTV

a diff. doesn't have any pressure inside it, so you can use RTV sealer as a gasket.

Well I did this in a Church parking lot because i smelt something (Pinion Seal gone bad kicking fluid on my pipe) So i opened my diff to see if it was low and this just started pouring out so I took a pic. And I think RTV is what the past owner of my jeep did because its a mess of a seal hahaha

If that one looks like that i would check the other one too. Cause that looks like a big puddle of water not oil

That's water in there, which explains why your pinion seal is leaking. That axle will be toast shortly if you've been driving it for any period of time like that.

Want to swap an NP242 or NP231 into your ZJ? Here's how:

Dumping on the church parking lot, classic Im just teasing because removing the plug shouldnt have done that. Looks like lots of water in there to me. Its an easy change.

If you have a trac-lok rear end, be sure and add the additive that it needs, along with the lube.

some of the higher-end gear oils come with the friction modifier already added...

Don't fear the regear.

My Trac Loc probaly dont work because it has near 190000 miles on it. It probaly needs rebuilt if i did that so do you have to add the additive?
