Should all wheels spin freely in park fully jacked?
My neighbor has a 2001 330XI. He is replacing the drive bearing. While the car was jacked on all fours he put the car in drive to rotate the axle to get to the other bolts on the guibo. He said it felt a little different when he put the car into park and after replaying his actions in his head he thinks the axle may have still been spinning when he went into park. Now all four wheels can spin freely while in park. The dash says we're in park. We can go into neutral, reverse and drive no problem and the wheels spin appropriately. The shift back into park feels fine. We did several tests to eliminate the differentials like spinning the rear wheels in the same direction at the same time. In all scenarios the wheels still spin. Are we just noticing this now and it's always been this way? Is this normal? Does the car go into some maintenance mode when all four wheels are off the ground that lets them spin freely? Any thoughts?
