So did he just like gut the transfer case and still use the rear output shaft of the transfer case? I'm confused to how that even works....

About the front hubs, I've kept the stock one and I've modified them.(The front ABS sensor stay stock).

How can I disable the 4WD fonction ? Do I really need a need tail housing for a new VSS provision?
Is there a specific PCM wiring for 2WD (and work with my rear Vss on my empty tranfert case?

Removal of the front differential case.

Hubs modifications:

See??

exactly, I've gut the TC and use the rear output shaft.
it works! I will take pix this afternoon. I'm running it and tuning it using Hptuners control for shifting.
I've got ABS light and 0 speedo (so no shifting), I can shift manually to 1 and 2 gear. (No DTC)

I'm living in France, output shaft shipping is expensive (long part). That's why I've choose this solution.

you need the rear most vss for your computer to read the speed in which it is turning, and if it cant read that it wont shift either, make sure you have the right vss plugged in
