    Quick update,

    I took the truck to a 4x4 specialist this morning. He did something I thought was brilliant and cant believe the dealership didn't think to do. He confirmed via sound the transfer case and front axel actuators worked properly, put it in 4x4 and did a full on brake stand in the dirt. Obviously only the back tires spun.

    After that he concluded that a look into the front axel/diff was warranted. His initial thoughts are either the actuator works while out of the axel but is tired or does not have the power to push while in the axel as one possible solution. Or the actuator works and the collar that the actuator engages in the diff is broke and the plunger just goes through that. With no obvious noise from the front diff, he initially ruled out something terrible gear wise.

    Unfortunately he was booked till next Fri, so he will start ripping it apart then. He had way better common sense and real world knowledge in my opinion than the dealer service manager.

    Ill keep this up to date with new info.

    We'll I got the truck to the shop finally. The mechanic deduced that the transfer case is slipping and says I need a new one.

    Guess I'll start getting quotes.

    I recently replaced mine in my 05 yukon xl. After searching around I found that going thru the dealer and buying it from GM was the best option. Mine was $1,300 from GM. They carry a 3 year 100,000 mile warranty. Since it is a power train part if you have any issues with it after install the GM dealer will fix it for free. I had mine installed at an independent shop thru the extended warranty company that I had at the time. Mine had a rear and front output shaft leak after a year. GM fixed it for free. I did not have to remove the case, just took it into the dealer. Other re manufactures wanted almost the same amount of money for theirs and it did not guarantee that they upgraded the back half of the case to remedy the known pump rub issue.
