I’m preparing for a road trip, a I just pulled off my wheels to take them in for balancing (maybe I don’t trust DT to properly jack up the rig… and partly b/c I have spacers). Anyway, I lifted the rear via the pumpkin, and then released the parking break in order to listen to the hubs. To my surprise, the rear wheels spin with the transmission in Park.
SQOD: the Park Pawl only locks up the front wheels?
The rear diff is what allows the wheels to turn if both rear wheels are up. Independent of whether the vehicle is in park or if the front wheels are off the ground.
If you only lifted a single rear wheel, it wouldn't turn.
