It is being suggested that the transfer clutch is holding retained torque against the rear wheel parking brake until this torque ceases when the engine is turned off, whereupon this available torque is applied to the front wheels.
However it is reported that at this point the transmission has been placed in park ready for the parking paul to engage. At which point the transmission should be running free and any retained engine torque should have been disconnected and released.
It would appear that engine torque must wrongly remain applied, when in park, until the engine is turned off. A control solenoid could be faulty and a diagnostic check is the obvious next step.

No Harvey hit the nail on the head... Constant fluid pressure is applied to the transfer clutch assembly... This w/ turning the vehicle causing an uneven rotation of front and rear wheels will cause torque to build in the driveline... Not until the engine is shut off and the oil pump ceases to create pressure is the clutch allowed to release.
