NP149 or NVG149 into 03+ Denali/Escalade?
so i've spent all night looking & can't find one recorded instance of somebody swapping the crappy BW4481 (open diff reliant on Stabilitrac & brakes for torque management) for the mechanical NP149 (NVG149) with the viscous coupling inside.
is this a possibility, or has nobody really tried in the last 15yrs? i see 50 million discussions about the 4x4 -> AWD or AWD -> 4x4... AutoTrac vs Manual shift... blah blah blah. i'm talking crappy AWD -> better AWD. is it simply a matter of swapping the front passenger axle & reprogramming the BCM to ignore the disconnected t-case?
i'm asking because i got to thinking i'd be about $20k richer to get a nice low-mile '06-ish Escalade or Yukon Denali to swap an NV4500 into rather than buying a new-ish 2500 Dodge (i only drive stick shift vehicles), considering the most i really tow is about 6000lb. the problem is the output shaft mismatch & all the electronic bullcrap associated with the auto trans driveline. the NP149, after doing the 32spline swap, would solve those issues, drive much better, and be stronger than the BW unit... handy for turboing afterwards.
am i off my rocker here? yeah, i could try to find an '02 or older, but then how much of a step up is that from the '99 i've been driving for the last 13yrs other than a back seat? this'd be a truck i'll keep for a LONG time.

and with 01 & 02 being the only options for factory NP149 SUVs, that also really narrows the available selection down.
that is, unless i break down & do a sierra denali - but then it'd feel like having a less-capable truck than a more-capable SUV... hard to explain why.
