2006 yukon xl denali awd

[Snotek27]

So I took my awd denali to get a 6 inch lift and put on 35s. Everything was good until they test drove it and front passenger axle blew out. Then there was grinding from transfer case and had to have that replaced. Both pieces fixed and then when they test drove it again the next axle went. Ended up using cv axles from 08 to. Correct length issues. Truck was then taken to alignment but the alignment guy had the truck in the air with the truck in neutral and all wheels spin freely. He saw when the truck was in the air in drive only the rear passenger spun to 40 mph and heard whining sound from transfer case. All other wheels would not moved and locked. On the ground he said when the car is in neutral car won't roll easily. When in drive on the ground the truck won't roll on its own. When it drives that it feels something is braking the car without hitting the brakes. Any idea what this can be? My car was fine before the lift and now have all these headaches.

Problem=Genius with the lift doesnt know that you cant run an AWD vehicle with wheels off the ground. The noise coming from your Tcase was your Tcase self destructing its viscous coupling and internals.
