might be dumb question but i noticed today that the rear wheels on my 85 berlinetta spin in park while being on jack stands.im doing my rear brakes and the rear wheels spin freely in park without spinning the driveshaft.is this normal or is something wrong because the rear end in my chevy truck dosent spin without spinning driveshaft and all.thanks for the help

 

Its normal. They are spinning in different directions - it's a open rear end.
