I have a 2011 Mazda CX-9. The car is AWD. Should all 4 wheels spin freely when on a lift and the car is in park and the parking brake is off? All 4 of the tires do spin freely. I believe I have a bad transfer case and was trying to diagnose if the transmission or transmission splines are shot before yanking the transfer case. Thank you for your help!

    In park I don’t think the front wheels should rotate. Also, you can switch into AWD? I had a CX-7 and I thought it’s full time awd.

      I thought the same thing. There is a AWD button on the lower left dash. Default is AWD off. When the front tires start to slip the AWD automatically engages to compensate for the front tires slipping. The AWD button allows you to switch to AWD manually.

    Yes, unless you have a locked differential. For park to work one set of wheels needs to have an equal amount of traction.

    What exactly are your symptoms that you think it’s a bad transfer case? Wheels spinning isn’t likely to be able to tell you anything about the transfer case.
