Twisted rear axle shaft

[Nay]

the first shaft was sent back to Nay and I have a second being turned.

If anyone wants to get in on the testing we can arrange a swap you just need to pay shipping and machine costs.

I fractured my tibia skiing over Spring Break (tibial plateau fracture), so I'm toast for another 4-6 weeks. Haven't even opened the box, but I'll let you know when I get somewhere with it.

I took the easy way out and took all the measurements fron the diff end of the shaft. So I'm not sure if they will transfer over to the poly shaft.

Personally I found the poly shaft to be inferior as by nature the chromemoly will twist sooner and creates the problem with less stress.

I hear what you are saying, but I think this needs a bit more examination. Chromoly is not designed to just twist - it is supposed to allow some twist rather than breaking and then "return to center".

What I hear you saying is "forget about the PP, because they twist", but this would only be a problem compared to stock if the e-locker is somehow keeping it twisted, i.e. the interaction with the locking collar is effectively countering the attributes of the chromoly and turning a commonly understood strength into a weakness.

Are you making the argument (I'm not saying you are wrong) that this specific e-locker application effectively negates any advantage of a chromoly shaft?

pretty much, The issue I had was that the chromoly twisted easier which caused a problem with the e-locker which would have otherwise been averted with the stock shaft.

With the e-locker it's not a typical scenario where twisting is preferred to breaking. Twisting is just as debilitating as breaking in that the rear axle is likely locked permanently and the axle is not likely easily removed.

in my mind the best solution is an axle if twisted won't inhibit the e-locker from functioning properly and if it breaks it will do so, so the diff can be removed easily.

maybe a chromoly shaft is still the answer but with sectioned splines so the twisting problem is eliminated.

Any updates on this?

figured it's time to bump this up....

any updates on this project? should I be shopping for a D60?

I can tell you that I wheeled the living hell out of an 80 rear with Chromoly axles and an Aussie locker (abandoning the e-locker entirely) while retaining the front factory e-locker and never had an issue or another break of any kind. If you wheel an 80 hard, this is a very viable option.

I hasve an axle myself and NAY has one also. They have been fine as far as I know.

Impressive work Rick. Any feedback on the prototypes yet?

 

[landtank]

nothing negative

Availability?

Right now I would need your shaft and then have it machined. I have a couple of shafts myself to do and would first have to talk with the machinist to confirm he is still interested in doing the work.

I really don't have the time to do this on a one at a time basis so possibly open it up for a group buy time of thing and deal with this as a single batch.

Let's get it on.
