Hmm I don't remember that being a hard spot to seal, usually they leak at the sector shaft. Check my supermotors for pics of my rebuild, it seems a popular spot for the Fsb guys to reference. If it's one of those seals where the outside is metal on metal, I like to slick some RTV around that to ensure it doesn't leak.

West Texas offroad. Not super helpful to you but it's how I fixed my box

Yea that's my last resort. I took the box apart and found that the last guy who rebuilt the box put the input seal in backwards like a dum dum :mrgreen: Teflon seals looked good so I put a new seal and bearing in there and put it back together. I haven't had a chance to install it so we will see how it goes after that.

By teflon seals you mean the 4 seals that roll onto the input shaft? My solution to those is to leave them alone. I've never seen a failure there. And I've caused a failure there cuz those things are impossible to get on :mrgreen:

That's exactly where mine failed. Good thing is, you pack a whole spare box.

Interesting. I guess I've now hear of a failure there. And yes I carry a second box, drilled, and tapped for hydro even.

And enough power steering fluid to fill it at least once? Throw in a pitman arm, mounting bolts and hoses and it really makes me hate this hobby.

The 4 Teflon seals were fine. I had installed the seal in the housing around the input shaft wrong. I still need to install it to see if that was it. And a spare box will be carried. Anyone have one laying around

I have a spare I carry too. Danny and I talked briefly once of cordinating large spare parts like that so that we didn't all need to carry such large heavy parts. Wish someone else had a dana 44 to share carrying knuckles with me. :P

The Scout II guys I sometimes run the trails with kinda do that, but most of the spares seem to be used up by the same guy.

Put the box back in and no leaks. Looks like the backward seal was the issue. So my sag swap is officially done. The knuckles are reamed and the tie rod is flipped to the top of the lower porion of the knuckle. Now I just need to ream the pitman arm and high steer arm which have been slow going. Might be time to replace danny's reamer

Wonder how many UC4x4 people have used that thing? when i used it someone other than Danny sent it to me, I sent it to Dave and I think he sent it to Larry. has anybody changed the tape-depth-o-meter that was on it or has that survived?

I used it to make "fifis". The taper gave it a different sensation

The tape depth o meter is long gone. One been using the drill stop check method. It worked great on the knuckles but it's slow going on the pitman and high steer arm
