http://www.diversifiedcryogenics.com/ Cryogenic treating looks relatively inexpensive, and seems to make things last a lot longer. Mostly what gets broke on the axles is teh joints right? Send those in and have them Cryo treated and see if it helps.

I wonder if they could get my whole car in there.

my old highschool metal shop /cad /cam /cnc shop teacehr does cryotreating or did last i knew

does cranks engine blocks anything pretty much that will fit in his cryo freezer

works well on gun barrels also

Yep, a lot of guy's are doing gun barrels/actions around here and the Toyota/Samuri gang are all doing thier Burfield's (spl?) I guess the guy that started doing the Burfields is in Graham WA, he's well known for it.

 

It would be nice if we could put a front stub in the rear, the fronts are solid as opposed to the hollow rear ones. I wonder if the 510 stubs are solid? Anybody know? I believe they are oart of the axle.

510 stubs are part of the axle kinda, they are the same as an EA71 U-Joint axle, there is one bolt in the center of the U joint that holds the axle into the diff, and then right next to the U joint there is a flange that the axle bolts to, but it is a lot easier to take the one bolt out, than to unbolt all 4 bolts holding the axle to the flange. The 510 axle wouldn't work on a newer car though, due to the way it attaches to the outer axle stub. Like the older soob, it has a 4 bolt flange, rather than the splined stub and spring pin. Perhaps someone with access to a machine shop could make some like, Chromoly axle stubs or something?

Keep in mind, if the stub is stronger, something else will be the weaker link.

What would be next?

Which is easier to fix?

That's right Ed. When I broke the stub on the Rubicon I was up and running again in 15 minutes. But that too depends on which end of the stub you break.

With cryo-treating our axles may still be the weak point, but still be stronger. I don't see cryo-treating doing so much to our axles that they will become unbreakable. I also think that unless the axles become unbreakable they would be impractical, because everytime we break an axle we will have to send a new one to the freezer. Any body know what people charge for this kind of work?

Nothing is un-breakable!

The point I'm trying to make is what would be next to break if the axle stubs won't, and how hard would it be to fix in the woods.

I understand a lot of 4x4ers use regular u-joints for just that reason, cheap and easy to fix.

Again Ed is on top of things again, like Ken said it all depends on what breaks. I would rather have the half-shaft break cost wise compared to the tranny.....
