Message Long. Maybe 1/3 to 1/2 revolution. When I turn them by hand I can hear a slight whrrr once per revolution… from differential… hub… not sure and don’t know if that’s normal. However when I had the wheels on grabbed them and tried to move them side to side and up and down. Seemed solid, no movement. No sounds or clunkiness when driving either. The CarX guy noted that as well, that there didn’t seem to be any typical failed bearing sounds but I wondered if it could be possible.

I will say the front wheels spin much freer, but they don’t have half shafts attached to a differential either.

How freely should they spin with car in neutral?
