I'm not going to pretend I know how the AWD works, but when I lift my car and engage first gear the passenger front tire does not spin.
My car will barely move forward or rear, the speedo climbs with RPM even though the car isnt going anywhere.
After doing some research it appears that its often an axle that has popped out. With the symptoms of the above test, can I assume its the passenger front that has popped out? When looking under the car it does not appear that any axle is out at all.
