Axle Slinger/seal

[gmduncan]

I have two, new Outer Axle Seal Slingers. I'll take a guess and say the parts I need are Inner Axle Seal Slingers...? If that's what they're called, where can I buy them? I found old posts and someone said to check with torqueking.com

I checked torqueking and didn't see the part I need. Thank you

That part doesn’t go on the inner axle shaft. Nothing goes on either inner axle, except for the seals inside the housing, next to the carrier bearings.

What year and model is your front axle assembly? I don’t remember ever seeing an inner slinger, but if there ever was one it was probably on a Dana 30 model with the outer axle tube seal.
And I’m not sure every Dana 30 had one of those even.

It's a '77 Dana 44
Here are two more pictures. Maybe I have my wording incorrect or calling the parts the wrong name. Looking at the top down view, to me, that seems like it's the inner.

Thank you...

I appreciate the help, but I already have the larger of the two parts. I just bought them...

What else can I do to show there are two different size axle slingers? Again, my terminology could be wrong. The one on the right is smaller. Look at the picture where I have the axle slingers, placed above the axle shaft. The "axle slinger" to the right is smaller and it fits on the axle shaft. I will be more than willing to FaceTime to explain in person rather than pictures. Thanks again and Happy New Year.

Looks like a slinger to me.
But all you can do is what you’ve been doing and look for a source of either a specific one or take measurements like you have been doing. Maybe somebody here has run into the same issue before and there’s a source.

In the meantime though, it’s not a wear item. So it doesn’t need to be replaced unless it’s already damaged. Just keep the existing ones in place.
If they are no longer a light pressfit, use a little silicon or epoxy to glue them in place.

FYI.. just tore down a 73 44 yesterday and it had the dust slingers on the inner shafts as well .. my 72 doesn’t though.. I’ll tell it doesn’t seem to make a difference on what builds up inside the axle tube though…

I rebuilt the front axle housing on my Bronco last spring. Its a '76 Dana 44 and, after a lot of research, I found Spicer part number 35168 is the correct inner axle slinger. You can get them now through Rock Auto. I got mine through Summit but they are currently back ordered there. I ordered an item of 1 through Summit and that was what I received even though the quantity states package of 5. Not sure what Rock Auto will do but you may want to order two. PM me if you end up with 10, I'll buy two from you as spares.

Was thinking the same...

Great find Master Chief! Thanks.

My 1974 had the inner axle slinger until I broke an axle. My replacement axles from currie didnt come with slingers and since the axles were bigger the factory slinger could not be reused. I gave up trying to replace them and have run over 25 years without the slinger. the slinger does nothing as when my old axle were removed there was loads and sand and crap inside the tube that had to be cleaned out.

I just replaced the small slingers, am I missing a rubber seal between the tub and the slinger? Just seems odd that the design leaves the tub exposed to water and dirt.

 

[DirtDonk]

No seal in most axle tubes. The slinger is merely to keep the bulk out, and especially larger items that can damage the axle shaft and inner seal.
The slinger design also allows the water that does get in to drain back out quickly and dry sooner.
Is it perfect? Nope, but there is so much flex of the axle out at that end that a standard seal would probably not last long.
I don't think any Dana 44 ever had an outer seal. Only the 30's and maybe some other designs. But the use of the seals was discontinued and the axle left open after that, other than the slinger.

The outer slinger behind the spindle is the same thing. It simply keeps the excess away from the spindle seals.
Same for the slingers inside an engine. They are to keep excess oil from splashing up against the seal and reducing the percentage that does eventually get past the seals.

Thank you for the clarification, great info here. Much appreciated Paul.

the inner axle my or may not have a slinger but there was not a seal for it. the outer stub axle slinger did have a seal which sealed the back side of the spindle. early dana 30 axles use a different spindle with a normal grease seal pressed into the spindle,

Apparently the 44s did as well. Doesn’t seem to be any real accurate consensus on what year the change was made, but Broncos came with both types over the years.
