Axle Vent

kenny811 · Aug 27, 2012

So I noticed my D44 was leaking and it seems to be fron the yoke seal. I also noticed the vent tube coming from the axle tube is blocked, I tried to put air from the tube bact to the axle tube, its blocked. Any thoughts?? Is the breather tube at the axle just go right into the tube?

Yep it goes right into the tube. Its not unheard of from them to clog up. I don't know how to remove it to clear it but i hope that answers your question.

It does. I have a place to start. Thanks Ryan.

I wonder if this might be causing my reap pinion to leak too.Ill have to go and check this out.

I figured if its not breathing and building pressure its going leak at the weakest spot.

The vent is just a plastic hollow piece pressed into the axle tube. To clean it out though just shove something through it, there's no valves in the way. Probably just gunked up oil in there.

With my old 44 I considered tapping it for a barbed fitting.

Ok so the tube was on a barbed threaded fitting in the axle housing. The other end of the tube plugged into a fitting in the uni-body rail. I unplugged it from that and just left it to breath under the jeep ( zip tied it to the fuel lines up high ). I didn't see any drips. Im thinking the tube in the uni-body was blocked or plugged.

I would hit the wrecking yard and pull some vents off and put a new vent on the end so you dont suck dust and water into the diff.

Good idea, I think I will do that.

I bought several feet of rubber line for my old toyota, ran it up into the frame as high as I could go with some loops in it to help keep out water, seemed to work pretty good. no issues with water in my diff, thinkin of doing it to the jeep now. whats the new way of venting your diffs now. been away awhile

I unplugged mine from the nipple in the uni-body, its just tied up high and no leaks. I hear the way is to get the old lines with the filter at the top from the JY. Or you can fit a small filter on the one there now. I think that how I will do mine.
