The inner CV joint sort of really, technically , known as DOJ (double offset joint)is the 23 spline variety to mate the 23 splines of the gearbox output stubs of:
std EA81 4WD
carb EA82 4WD
turbo auto EA82 4WD
A post on another forum got me worried enough to investigate to find it is not a simple swap of DOJ on the end of the EA81 4WD axle shaft to be able to make use of a 25 spline output stubbed gearbox.
I have pulled apart a 25 spline DOJ and a 23 spline DOJ - i suspect both were off 4WD
The 25 spline of the stub axle of the gearbox carries through to the 25 splines of the axle on the 25 spline EA82 axle assy
The 23 spline of the stub axle of the gearbox carries through to the 23 splines of the axle on the 23 spline EA81 axle assy
crazy as it seems, I recall the 23 spline stubs on the garbox step up to 25 splines at the crown wheel and pinion !!
every component of the 25 spline DOJ is that much bigger than its counterpart in the 23 spline DOJ including circlips and balls ! so nothing can be swapped/interchanged in order to do want I need to do, which what i was lead to believe - was simple- It ain't yet !
I need to be able to run a std 23 spline EA81 BRAT axle with std outer CV joint, but with an inner DOJ that has 25 splines to make use of a 25 spline gearbox I have been hoarding for many years.
I could simply ask - how do I modify the CV shafts of an EA81 to run an AWD5 manual/stick box from an EA82 - please ?
I recall info about doing EJ conversions and to use FWD EA81 manual, or was it auto inner DOJ cups etc to graft an EJ box to EA81 front hubs etc, there must be something I am missing, and someone on here must know, and be able to say in simplest terms..
An inner joint has the cups also known as outer race, to which the inner race (which has the splines) and balls and cage , fit neatly into. I cannot just take the inner race from a 23 spline and fit it to the 25 spline cage and balls.
Help would be appreciated
