PS Front axle seal on a d30

[Car RamRod]

I'm leaking gear oil from the passanger side on my d30. I searched and it seems for the driver's side you need to pull the differential, but what about the pass. side?

I'm gonna change the seal, bearing and u-joint while I'm there. Anything else I should hit?

 

Thanks

Is this a front axle with the vacuum disconnect? If so it goes in and out through the disconnect opening.

Wow, looks like I'll just be changing all the seals on the front axle.

Yup.

Hey I'm having a little trouble locating a replacement for the passanger side axle seal (with disconnect). It seems like all of the write-ups are while converting to one piece axles which use a different seal.

 

If anyone has a part number for that I'd appreciate it!

NOS (Napa Oil Seal) 11771 from your local Napa store.

....... :fs1: mine is now doing this. Ive had it on the road for a week.

Every time i stop.... it makes a little puddle about the size of a 50 cent piece.... :fs1:

 

So... the seal is in the pumpkin next to the diff? its not out at the end by the joint?

[mountainman]

Happy now. I found this.

and rockauto has the seals. So ill be tackling this soon, i even planned a write up too but..not needed. Stu is the man. lol

My god, I can't believe this was a year ago.

 

I jumped through a million hoops and finally got the right parts. I'll dig up the numbers that worked for me. IIRC, I needed seals specific to the 1986 model year.

Ok here's my few pictures. As always I mean to update my threads but I was so agitated by this one that I forgot to. One of the seals was a real PITA to find the right one. I tried all the seals offered by my commercial parts warehouse, and the aforementioned NAPA seal. They were all wrong. I pulled a number off of Autozone's website, cross-referenced and got it from my local guy. Bingo. Again, I think my truck being an 86 was the issue. What a headache this was.

 

Here's the numbers and what they look like:

 

Seal driver:

 

Primed:

 

Painted:

 

I hope this helps people in the future, I know I was going nuts.

ok question.

So is the seal in where the disconnect fork is? since you have that hole in the pic? or is it in by the diff like all the rest?

[Car RamRod]

Yes it's outside of the fork. Hence the fork is lubricated (when you open it oil comes out).

[mountainman]

whoa... so i don't have to pull the diff? i can just tear down that side and change the seal outboard? thatd be SWEEET.

I want to do a 1 piece axle down the road, but for now thats low on the list.

Need tires ASAP and not gonna buy 800-1k in tires and then lift and need tires again.

So going up a bit before tires.

THEN axles are next. :)

I don't recall 100%, but I think I pulled the diff to make it easier to drive the seals out and in. It's not really a big deal.

You may have to pull the inner shaft to have enough room to work with. And the inner shaft has a C clip inside the diff...
