I don't get it. Why are Superior's front axle shafts *thinner* than stock? Why would this be a good thing???

chrome molly are stronger i guess

 

The best way to design an axle is to do "wasted body". This means that the body of the axle is the same or smaller in diameter than the root of the spline, this design allows for torsional deflection. If you make the body of the axle the same size as the spline or bigger, the weak point will be the spline.

 

Can you explain that more? I was certain it was just to bug the crap out of me as far as fixing the leaking right side. i finally bought AlloyUSA's and put in a stock seal to stop it.

 

Aaaaaaahhhhh... So you're saying the shaft will break before the splines.... And breaking splines, probably followed by a bunch of stuff in the diff, would be worse. Hm. Makes sense. And comforting to know, considering I'm using CTM u-joints with those Superior front shafts! :-) I was worried the weak link might be the splines or something else in the diff. This way maybe the shaft will be the weak link (it certainly won't be the u-joint!). :->

So it sounds like seer1 should stick with Spicer u-joints! :-D

The Alloy front shafts appear to be the same thickness and contour as the stock rubi shafts, but made of chromolly. I believe the u joints are bigger with the Alloys than the superior. I got a hard time believing anything is going to break before that ujoint...

 

I'm with you on that. It is and the Superior is only .010 thinner. Just enough to with the stock seals. And yes, the U-joints are quite a bit larger.
