LEAKAGE. Do not know wur its coming from

[JHarris1385]

Not to sure if I am up to the challenge of the adding that seal? Willing to learn. How hard would that be?

I might as well go look at it tonight and change the oil? 75W90 right? How many bottles?

If it is the seal is there a temporary fix?

Thanks for the info and the diagram.

You may want to go 85 or 90/140 this time of year, go back to 75/90 in winter.The job itself is a fairly complex and time consuming one. If you are totally green on 4x4 front ends, it would be a good idea to,at the very least, have some help from a bud who has cracked one before. You may want to farm this one out...it won't be cheap though. If you had the Helm manual, and a decent set of tools(snap ring pliers, torque wrench etc.) and a bunch of time, you could do it. Second time through, it goes much more quickly How are your CV's, tie rod ends,wheel bearings and such...you'll be in there anyway Good luck either way you go. Wayne

Having just done a lot of work on my front end, I can tell you that it's a PITA to replace that seal. You have to tear out a helluva lot to get at it, and while you're in there it sure wouldn't hurt to replace the inner bearings(I did) since they are pretty cheap, and after you know what this is like, you're probably not going to want to do it again. Be very careful getting your upper and lower balljoints separated. I tore two of the boots on mine, and just ended up buying four new complete units. You pill probably need a balljoint separator(AKA pickle fork) and a bearing press helps a lot too. I know mine were in plenty tight and after soaking them well in advance with PB blaster and beating on them with a 5lb. sledge for quite awhile, they still didn't want to come out. The book is goin to tell you that you need some special tools, but they can be ignored if you have a little ingenuity and some common sense. I would take a good hard look at those CV boots while you're in there. Mine were showing signs of dry rot cracking from the nasty desert I live in. Good luck.

I would have to say I have now become completely discouraged to do this repair. I wish I was more confident with this. I would really like to learn this but am to afriad I will damage something in the process. I forgot to upload the pics I took last night. It seems like it is just not a slow leak but spinning/spitting out of the gap between the two becuase the metal above it is wet as well.

Take it to a Cv/axle joint. The only downside is you won't get to do all those bearing, boot, tie rod end swaps, unless your pockets are deep.Swaping the front axles entirely is probably the cheapest and easiest way to go...I would be inclined to do both at the same time though.

Damn now I am worried.

Hate to add to the injury but here's some news you should know.

It suddenly dawned on me in the middle of my day, " hey that dude has a bad bearing and that's why he's seeing fluid slinging out, AND hearing a noise. He needs to get in there soon!!!"

Yep. I think you have a bad bearing, the seal is completely worn out because of the excess play in the bearing and that's why it's leaking.

You need to do something soon!! You could do this I think. Yes it's intimidating but you can do it and you should because labor to do that seal is gonna be (educated guess) about $400 - $500.

At any rate, I think you should take action soon and at the very least, top off the diff oil!!!!!!
