I have purchased ARB for 30 splines and drive axles Rcv 30 splines in both outer and inner ends. Now that I'm going to mount these, I see that they do not go through the hub.There is no material to drill this up.
Anyone who knows if there are stuff to buy so I can get yours these ?? Otherwise, I can order new RCV short drive axles(stubs) with 30 splines in the knot and 27 splines at the hub.
What and how do I do?
:confused:
Thanks in advance
 
When you say hub are you refering to the lock out?
 
No not lock out, I mean to able to mount coarser drive shafts in the spindle(snout) .
Orginal is only for 27 splines drive shafts.
I must find parts so i can mount my new 30 splines drive shaft.
Someone who know what suits and where to buy the parts?

I’am sorry for my bad english.

What's the diameter of the 30 spline outers compared to stock?

I would try calling RCV and see what they recommend for the outers.
 
I mean if you can bore out the spindel so that the new 30 spline outer stubs shafts fit. There will not be much material left, especially not where the track is to lock the nut.
The question is if that's how I'm going to do? Does it hold for drilling?
Will it be strong enough?Anyone who did this?
In the case of the freewheel hub, it is easy and is available for replacement.

My CJ does have the 30 spline front axle, Dana Spicer 297x u-joints, and a 27 spline stub axle. I did this years ago and purchased the parts along with a custom built Dana 44 front axle housing from a local builder, brought it home and put it together using the Dana 30 spindles.
