Yes, Rzeppa. But I'm not convinced the factory size or angle capacity is a problem at the diff. We will certainly sort that out though.And by high angle CV at the pinion end I was specifically referring to a high angle Rzeppa style joint, assuming it can be built with a stronger more high angle version than the OEM Rzeppa. A single cardan joint is not possible on the pinion end as it can not be properly aligned without unacceptable changes to the caster angle.
The Tcase joint seemingly fails due to a failed boot and the subsequent release of all its life blood. Once the grease is gone the joint starts to fail rapidly. That said, I have yet to see where the joint fully failed except for one guy whose C-clip on the joint failed.
