When you jack up the front end up and spin one wheel does the other side spin as well?

I used a front differential out of an AWD vehicle too so I wouldn't run into any issues with the old locking hub front diff. That could be your problem. Not sure though.

On a 4x4, the hubs don't lock, but actually the right side axle is a two piece that locks together, while the AWD has a one piece axle which to me seems like it would be stronger

im glad this thread got brought back can we get more info on this swap... other than bolting up the t-case, axle, and shaft what else needs to be done for this to work properly?

Oh, thanks for the info.

Before buying (4 months ago?) I was mildly disappointed that I couldn't shift to rwd for playing around in the sand or snow, but now that I've driven it in winter, I far prefer awd, that way you're never caught off-guard in 2wd. Especially driving on half clean roads. Glad to know it might have a stronger front axle setup too. Bummer I'm pretty sure I don't have LSD front or rear, but htat's ok.

While I'm typing about it, when I spin the tires a bit too much in the snow I get a little kind of grinding/slipping noise. I try to not do it though I'm thinking it's probably normal, as otherwise the truck drives mint. Can someone verify that noise is normal or do I have a ticking time-bomb?

Also a guy at a junk yard told me the two rpo differential options for my truck and that one was better, mechanical instead of electronic, and I had the better rpo according to him when I checked later. Not sure exactly though, any other info is appreciated.

The option code for the NVG-149 would have been NP3, but as far as the noise is concerned, it could be as simple as you are causing the viscous coupler to go into hump mode if you’re spinning the tires viscously or a stretched chain. These things are pretty reliable, but they do suffer from the same type of issues that regular 4WD cases have plus the non-typical viscous coupler failure from time to time. It’s not 100% as anything can wear out, but usually failures of the coupler arise from abuse, whether it be from lack of servicing, causing the unit to overheat or humping the unit also causing it to overheat.
