Isn't that how the rear axle operates, to some extent?

 

LOL I thought the same.

 

TOO FUNNY!

 

Seriously, I would love to hear the story about that first picture.

 

This picture I 'borrowed' from I do knot know where, to make a point. I haven't a clue how that could happen. I do not think gear oil by itself could ever become that.
Looks like asphalt or crude oil.
The second picture I posted of the tube seal is mine.

 

To an extent i guess.The inner seals still keep your diff submerged in fluid no matter how off camber you are.. Filling an axle tube with diff fluid would not.. The fill point is well below center meaning if you filled it all the way up with no inner seals you would probably only be about 1/5th of the way to filling your able tubes... Meaning when off camber, it would drain to that side leaving the diff with no lube...

The outer seals work great for what they are designed for... Too keep mud/water away from your inner seals. The reason they tell you *important... Run inner seals* is not for liability... Its so you don't destroy your diff.

They do have a possible downside as well... Anything that does get in there is trapped in there.

 

The fill point is slightly above center.

 

not even to some extent, that is EXACTLY how the rear seals work.

 

*edit* ignore last post.. I'm wrong

 

and all of those axles have only outer axle seals.

also, the 8.8 fills above the centerline from the front of the pig :P

 

You are correct.. Only the old D44 rears have seals. I would not run without a inner on the front but I feel like I am arguing a useless point at this point lol.

 

i wouldn't run without the inners either, those outer seals only seal with rubber on the outside, they aren't a press fit, i don't like that.

 

Sometimes putting a new shaft and an old seal or new seal on an old shaft might cause leaking for a few days, sometimes it will never seal properly and oil leaks out while sand, mud, crap leaks in. Over filling the diff can sometimes cause leaks as well. You might want to give it a few days to see what happens. If the leak stops and your gear oil level is sufficient then you can run the outer tube seals and have double protection from crap getting into your diff. Remember to always use emery paper to polish the shafts where they contact any seal anytime you pull axle shafts.

 

^^ Good advise.
Also when installing tube seals I clean out the tubes and axle shafts and coat both in grease before being sealed up.
Most shafts are pitted where the tube seal will go. Emery cloth is a must.

 

Good advise Steve and Schirm.

I already have everything apart again sitting at home waiting for me. I did not clean out the axle as well as I probably should have, so I am taking it slower this time and making sure to leave nothing to chance.

I will certainly use emory paper (great advise) after I clean the axle tubes out really well. This just gives me better practice on breaking things down and putting them back together if (when) I break something on the trails.

On a separate note, as I was behind the house testing out the Spartan locker that caused me to go through all of these gyrations in the first place, it worked awesome (course this is coming from a guy that is used to open/open).

I am quite excited to get all of this buttoned up and test it on some real stuff.
