Alloy Tube Seals on a D30 - Worn?

I have Alloy tube seals on my dana 30. The have been on for about a year. Originally both were tight and would not rotate in the tube. Now one does Is this a problem? It moves in and out of the tube to the point of resting against the ears of the shaft. Needless to say, I don't thinks it is sealing anything. Do I have to pull the whole shaft to press it back in? Do I need a new seal?

If it's going to press on, you don't need to remove the shaft to do it. Just push it into the tube. But I don't think it will stay put if it came out the first time. Mine are so tight that I'd have to ruin them to remove them. That's how it should be. Just get another one. They are definitely a great thing to have if you encounter any water or mud at all.

I have pushed it back in by hand and tried applying a bit more leverage with a screw driver only to see that readily moves with little force applied to it (hand). The drivers side will not budge. The passenger side does now. I am guessing that the o rings are shot.

Does anyone know if you can pull them off, clean them up and re press them? Buying a new one isn't the end of the world by any means, but I want to have the parts in hand if I end up having to pull the shaft. The less down time the better.

You could call to find out what size o-rings are used, order new ones, and put it back in. You'll obviously need to pull the shafts.

Thats kinda what I figured. I was really hoping there was a way to avoid pulling the shaft. But thats what you get when you use your Jeep.

Did you put RTV on them when you installed them?

Read here: http://www.jeepforum.com/forum/f9/fr...runout-944532/

i think you'll find removing the external seals all together is the easiest thing to do....

I had one size that started to spin with the axle. I just removed it and reapplied a better dose of RTV and reinstalled it. It has been fine every since. Make sure to keep them greased.
