I've seen a few toyota's sheer the teeth off the pinion to where it almost looks like clean blank pinion, and the ring gear looked ok lol.

As for shaft breakage, don't get me wrong, I didn't claim that they break at the splines more often than the shaft body, because they usually dont due to shafts these days being tuned properly, but to say they never break there isn't true. They break their often enough.

As for the original "argument" if you will.... Alpha/Omega completely twisted my point around backwards to fit his own argument. He claimed two shafts of the same diameter and different spline count have minor strength differences. That is 100% false.

I think anything after this is beating a dead horse. Alpha/Omega, you were wrong, I have told you why... if you want to continue trying to push your false points, go for it... without me.

The entire basis of your feeble attempt at making a point is that the splines are the weak link. We have all explained to you that shafts very rarely break at the portion of the shaft that you claim to be the weak link so experience tells us that your assumption is wrong. By your claims a 14bt shaft would be weaker than a Sterling or 70 shaft and that simply is not true. I maintain that in 99.9999% of all offroad situations where you would break a 23sp D70 shaft you will also break a 35sp shaft, all other factors being exactly the same. - the point being that neither break will be at the splines making it a moot difference.

Before you come in here again trying to start trouble make sure you have a good understanding of all the facts and working knowledge of the parts we are discussing.



The mods really have us hamstringed as to what we can or cant say.

 

Spline count, and design both matter, yes, overall axle size and material are the major factors, but, spline count does affect stregnth.
Outside of the off road world it obviously isnt a huge factor, class 7 and 8 stuff is pretty damn coarse, but, it is also HUGE.
In our world, where physical size and weight are also a factor, spline count is very important; the more contact points between the axle splines and their mating parts, the better, however, in the case of the 14B, it has a much better pressure angle(angle of cut on the splines) and it's lower spline count matches the stregnth of a 35 spline dana axle. While spline failures aren't common, the do happen, and for a given axle diameter, say 1.5, a 35 spline axle has a much greater contact patch than a 16 or even 30 spline. Given the same materials, the 35 spline axle will be stronger at it's contact point with the side gears/hub/etc. Strength down the unsplined portion of the shaft is affected entirely by material, construction, and heat treating.
However, 99% of the time in automotive apps, higher spline count = bigger diameter, and that always = stronger.

AIC: Odds are what you read of IH has more to do with machining and hardening issues rather than actual spline count, depending on the date they did that, it may even have been a material issue. Technology has brought all of the above a very long way.

 

I'd like to add this to this Super Tech Thread and request it be added to top of page as a Sticky...

and Id like to add your youtube vid posting abilities to the fail thread

Ill second it to be added to the tech sticky though.

 

added tech vids fixed

 

i second this!!

 

yes it was a fail
