Well it looks like the breather is blocked for my front diff. There was oil leaking from the front pinion seal today. I crawled under there, and the hose that was attached to the breather elbow was cracked and the elbow itself was packed full of mud.

I plan on changing the diff fluid tomorrow, but what is the best was to unpack that elbow? It is pressed into the diff right? so there is no was to take it off. I was thinking of using something thin to poke the mud out, and while doing that have my shop vac to suck out all of the crap.

Any other ideas would be great.

 

If I remember correctly, when Austin, myself, and Corey were swapping front diffs or dropping them, one of our elbows came out out of the diff housing. It screws in and is a pain in the butt to put back in the dang thing.

I think we fixed it using JB weld then some silocone. I really want to change the design of the breather...make it alot like the rear diff breather...just a virtical hose fitting.

 

Hmm, well it is going to be even more of a pain in the *** because the diff is still in my truck. There is Noooooo space in that thing, none!

But what I did worked. I drove around for 15 mins to get some pressure in the diff, then I got a metal BBQ skewer, stuck her in there, grabbed the vacuum and she came right out. There was a pretty big hiss, then everything worked.

Win for me. Now I have to go and find more breather hose.

 

Belive it takes 1/4" ID hose.

 

Thanks shane

 

I could probaby break that down to millemeters if you want me to...

 

That was low...lol

Come up here, I dare you!

 

lol

 

HAHA...ok...we'll see Mr. Enterlastnamehere!

 

if i were you, i would remove it and replace the axle seals as well where the CV's go in. because if the pinion seal is leaking, trust me, the outer axle seals arent far behind, im on my 4th set of outer axle seals. and that vent screws in on most of them. mine has 5/16 vent line going to it

 

Well I drove it around today, and there is no leaks what so ever. I cleaned off the Diff of any excess oil, and after about 20 mins of driving in 4wd, nothing came out. I think it was because that vent tube being blocked. The vent line itself was split right at the elbow going into the diff, and the elbow itself was packed full of mud. I am going to keep an eye on it, but I am going to chalk this one up to the blockage.

 

im with toreador4x4 on the seal thing. . .i just did my pinion seal when i put my locker in and now my outter seals are leaking. Should of just done it while i had it out but o well.

end hack

 

Well what I think is that the pressure forced the oil out the weakest point, the pinion seal. But if it is the pinion seal that is leaking, I am definitly going to take that advise and change everything at once.
