had car on the ramps earlier,and when i spun the rear wheels,the opposite wheel spun the other way,i thought both wheels should spin both the same way,i enquired at my dealers and they said this was normal,is this correct or are they fobbing me off with bull ****e..

thanks in advance

 

There right, the wheel opposite should spin in the different direction

 

Its only when they lock under load ie one spinning that will engage some sort of clutch which will lock both wheels together. Limited slip differential LSD.
