You are going to have to be a bit clearer in your description.
If you hold the spur while also holding one of the "rear" wheels, the other "rear" wheel should not spin freely by hand. What should happen normally is... if you hold 1 wheel and give slight throttle, the other wheel should spin under power. This is how a differential works. You can also hold the other wheel and do the same slight throttle and the free wheel should now spin. If not, your diff is too loose or damaged.
If the suspension is set correctly, none of the wheels should lift off the ground.
Do us a favor and set your car on a table and take a close picture from the front and rear of the car showing how the suspension is set. A picture is worth a thousand words.
