My plug isn't really bad, but I'm thinking of swapping it out since I'm draining the oil. It does come out...I just want to replace it before any issues.

Looked and looked and cant find part number for it.

Anyone know this?

Make sure you can remove the fill plug before removing the drain plug. Sometimes the fill plug is seized and you can’t refill the diff.

I did. It does come out all the way.

Just looking to replace it. Not a necessity but a desire.

Up here to the right
I said FILL plug. Believe me, there’s plenty of people who remove the drain plug, drain all the fluid, THEN find out the FILL plug won’t come out and they’re screwed. You can’t add fluid into the drain plug. Happens a lot in the rust belt. Just a heads up. Not sure on the drain plug- are you talking the one in the cover? I think you just need to buy the cover with the bolt in it, they’re not expensive, maybe $20.
Another ‘dig’ at my rusty ass trucks...;)

almost time to move outta here...

Thank you swathdiver SOOOO much.

Ordered it. Not cheap for a silly plug...but the any bad alternatives are worse..:)
@new2yukon am I mistaken or did you originally ask about the drain plug? I am hoping I’m not getting so old I make mistakes like that but anything is possible!

Mark, Mark, Mark, Mark, Mark, Mark, Mark, Mark, Mark.....the thread title. Usually it is this old guy, 67, not reading correctly. I don't feel so old now. Thanks!

Ummmm... you DO realize thread titles can be changed by the original poster, don’t you? Because I swear it was titled “PN for rear differential drain plug” at first and was changed but like I said, maybe not. That’s why I asked @new2yukon but he still hasn’t answered....

Mark, I did not know that you could change the title. Thanks for the info. All I ever saw was "fill" plug.
Any thread that you start will have the option at the top right that says “thread tools” with a down arrow. Hit that and the drop down menu has 2 options- edit title and add a poll. It’s real useful if you want to change the name of a build thread or add “sold” to the title in a classified ad. Or correct a mistake.....

Yea, I just figured that out. I saw what you said and went to a thread I just started in Detailing and saw the thread tools and opened it. Thanks for the info.

Oh. Crap. I slowed down and more clearly and the AAM might be only for the drain in cover style.

But it looks like my fill plug. Maybe it will fit.

Not a huge waste if it doesn't I guess. I cleaned up the threads on the plug and lubed w/ antiseize and will prob grease around it as well. This fill plug is on the diff case....not the cover.

And yes, this is about the FILL plug.
