Maybe the rear end

I am not clear on what you are trying to do. If you are trying to spin the wheels by hand, your car is a rear-wheel-drive model. The front wheels are free to spin. The rear wheels had better not turn if only one is off the ground. If it could spin, the car would roll away when you parked it on a slight incline. If you have an "open" rear axle, you will be able to spin one rear wheel by hand when the transmission is not in "park". Typically it will turn easier in the forward direction than when turning it backward. If both rear tires are off the ground, and the transmission is in "park", turning one wheel forward will cause the other rear wheel to turn backward.

If you have an optional limited-slip rear axle, the only way you can rotate the rear wheels is with the transmission out of "park", and both tires must be off the ground. When you rotate one wheel forward, the other one will also rotate in the same direction.

If a third option is that you can start the engine, put it in gear and the car does not move. That could mean transmission damage, whatever took out the tires may have damaged the transmission pan/cooler lines and you have no transmission fluid, or it damaged the shift linkage so it is not shifting the transmission.
A good visual inspection would help isolate those. Pull the trans dipstick - is there fluid on the stick? Does it do anything when you shift? Idle speed change at all?
If it has fluid and no changes when you move the lever, check the shift linkage and cable underneath.

You still have not said what the problem is or why you are trying to do whatever it is you are trying to do. That is why you got three different answers for three totally different symptoms. From everything you included in your original question, you could have absolutely nothing wrong except you are expecting the rear wheels to do something different than what they are doing.
