Question on rear axle seal leak

I am curious if anybody has had this problem?

I have a rear dana 44 non rubi that I just upgraded to Yukon 35 spline axle and ARB locker. We got the yukon kit with seal and bearings. About a week after driving the Jeep my axle seals started leaking were the axle shaft goes through the seal and bearing

Do you have an aftermarket diff cover? If so too much oil may have been put in causing it to leak

Yes aftermarket but still use factory amount of fluid

Dont those seals get pressed on? I dont see how it would leak around the shaft. I know after I did my gear swap I got some leaking out of one side. I pulled the shaft and cleaned off the seal and the housing where it sits, didnt have any problems after that.

I've seen too much gear oil cause it to puke out the breather tube. Never seen too much oil in the rear diff to result in a leak from the outer seals.

Longtime lurker here.

Just put in ARB lockers as well, do you know if your housing was ground to allow oil to flow back around carrier bearings. Maybe too much oil being trapped in tubes. Just a thought.

Now I'll go introduce myself

Not sure I can find out. Do you have more details on grinding ?

It shows where to put the oil drainage slots in the instruction guide. The axle hasone per side but they are up too high, around the 1 oclock positions, you need to make two more around the 5 oclock position(one per side).I found a link:

http://www.jeep4x4center.com/arb-air...arb-rd117.html

Click on the pdf instructions and I think it was in section 3.1, there's a big picture of the diff housing that shows where the bottom two slots should be ground out for oil drainback. I noticed when I looked again it has a big "IMPORTANT" box that describes exactly what it happening to you. It says that inadequate oil drainback will pressurize the axle tubes and cause oil to expell out the seals.

Yes.

With the rear axle, because oil is shared and scavenged between the diff housing and the axle tubes/outer bearings, there needs adequate flow paths past the carrier bearings to equalize the pressure.

Is the leak only from the driver side tube?

seems like if the axle had poor drainage now it would have had poor drainage before the ARB/Yukon shaft install, no?

Yea I would think so. Here's the quote, sounds like a design flaw that was changed. I had leaks in both sides before I rebuilt my axles, brakes were oily and dirty, surprised my ABS sensor worked at all.

IMPORTANT:
Some Salisbury axles were manufactured with poor oil drainage
between the axle tubes and the differential housing. This can
often result in one of the axle tubes filling up with differential oil
while running. In most cases this will result in a blocked air vent
which will cause the differential housing to pressurize and expel
oil from the axle seals at the wheels or force oil into the air
system of the Air Locker, eventually expelling oil at the solenoid
valve. This is a design flaw which was corrected by most
automakers in the later releases of their axle assemblies. If no
lower drainage point is present in the differential housing then it
is critical that you modify the housing to include one.
