Would it be a good idea to replace my Dana 30 axle shafts with chromoly?

I’ve seen those but the downside of those seals is that you won’t know if your inner axle seals are leaking
Yeah, you would think so. In reality though your gear lube will work it's way thru the grease barrier of the outer seal. It'll thin the grease right out and present itself plain as day. Ask me how I know... ;)

I've pulled several long side shafts and the axle tube was full of gear oil. There was no indicator on the outside of the tube seal that had happened.

I wish you would have read the instructions on the little square of brown paper in the box with the u-joints.
I’m guessing here but I had instructions something about not mixing up the caps? How the right amount of grease was placed in each cap...

Dang, mrblaine, what did it say? I took the u-joint paper off and did not even see any instructions. I went back to look fot the little paper but couldnt find them.
 
One of the dumber products out there.
And why do you feel that way?
My typical trail environment includes plenty of mud. My gut says that isn't the case for you?

It says that there is a very specific amount of grease put in each cap at the factory and since we can't predict how much will stay in hte cap and how much on the cross when we pull a cap off, each cap should go back onto the trunnion pin it was removed from.

Yes, and the way you know that wasn't done is the lack of markings on the caps and cross. ;)
man, ya know i called and even asked about adding a little grease to the caps, was told I could dab a little inside,, but if i put too much the grease would ease out he little seals. So i did add just a dab or little on my finger to each cap , so far there is no grease coming out the seal
 
What did 4 wheel drive vehicles do before those became a product?
My guess is that they drove around with axle tubes full of mud?
I know that's what I was doing before I added the outer seals...
 
when yall are doing axle changes , do you also change out he hubs for good measure? im sure its a great time to look at ball joints too. mayby even change out front brake pads if needed????

Just because folks say stuff, does not mean they know what they are talking about. Right from Spicer, right out of the u-joint box.

And that was such a big issue that the OEM went a very long way to figure out how to solve it, right?
