Had the tires rotated and cpl days later get a grinding sound and it will roll in park if center diff is off. It won't engage, just some spinning and scratching noise!
 
Check your drive flanges. It sounds like they may of sheared a few splines...they transfer the power from the CV axle to the tire (located under the dust cap on the front wheel hub)
 
Diff went kaboom........, pop the caps off your front drive flanges and see if the circlips are still in place.
 
This happened to me a couple of years ago. Hub flange and half shaft were replaced. Wasn't cheap, but it was much cheaper than a transmission.
 
Sounds like internal transfer case issue to me. I'm new to the 100 but if it rolls in park and drives with the t- case locked, it's not the trans. If it was the rear diff. Wouldn't the computer sense the difference in wheel speed between front and rear and engage the front diff too move the truck. Just my .02 not real familiar with the way the system works yet.
 
It is your drive axle flange in the front. Remove the center cap from both wheels and you should be able to see the end of the cv shaft spinning within the cap when you put it in drive with the center diff unlocked. It would be a good idea to apply the parking brake first for safety when checking this (although the parking brake levers are probably stuck and ineffective like the majority of landcruisers out there) . The passenger front drive flange cup went bad on mine and caused the exact same thing to my 2000 landcruiser. Not really that big of a deal to fix. Good luck and let me know if you have any questions. I know all about this repair.

I hear you about the parking brake buddy!

Could be this, but doubt it since he wasn't wheeling or stressing it.

Yup probably this.

If the front Diff or cv broke, I would think the rear axle would still move the truck.

The rear axle won't move the truck unless it's getting power. If something up front is free-spinning you're putting all your drive to that point. Have to lock center diff to get power to the rear axle.

Back to the drive flange, it's probably this. When TT05 said remove the center cap, he means remove the wheel center cap and then the dust cover that's pressure fit to the drive flange protecting the components inside from dirt/moisture.
