So, besides getting this transfer case for free, what were other reasons that led you to do this conversion? Was your stock transfer case needing repairs or you just wanted to do it for the sake of experiencing?

Adding efficiency to the drivetrain while adding clearance underneath a Jeep is one hell of a mod in both directions!

It was a mixture of less drag and more clearance. There were reports of decreased fuel consumption but I always took them with a grain of salt.

My car is the smallest in the club, no lift and only 32 inch tires, so it needs every bit of help off-road. It would always drag the crossmember on obstacles. I gained 4cm clearance with the new transfer case and the new crossmember.

It needs to be able to do this and then switch to road tires and drive as economically as possible

Even though you'd take it with a grain of salt, switching from full-time 4WD to part-time improves fuel-efficiency nearly everytime.

New Parts / New Venture promised that the georotor design in the transfer case would direct 100% of the torque to the rear wheels under normal driving.

I guess after 16 years of wear and tear and possibly incorrect fluid, the clutches inside start to add drag.

I'm anxious to get some real fill-up data and see the difference.

Interesting, but I wouldn't hold my breath for that.

New muffler is on and tucked almost 1.5 inches higher:


The exhaust no longer hangs lower than the crossmember:


Due to the madness in Europe we will most likely skip going to Greece this year, so long-distance fuel consumption data will have to wait a while.

Any gains from the drivetrain mods should still bring down the average fuel consumption, so I will update this as I get new data.

Turning the output yokes by hand once it was removed showed quite a bit of resistance.

The old transfer case funded the exhaust mods

Seems like the decoupling only works with the engine on. Well, I never held my breath for those "automatic 4WD" systems, unless they had a proper center differential which IIRC some SUVs from the '90s didn't resort to and relied mostly on sensors input to engage and disengage the front drive. And once the clutches wear out, it may become worse to drive on pavement.

That sounds good.
