Bought a used manual ford mustang 2014, huge reversing problem. Transmission?

I bought the car for around $15k. It seemed pretty good, but i noticed the reversing problem after purchase. So when i put it into reverse and turn the wheel fully to the right or left, it seems like my car is hitting something and my car is driving over a huge rock. And then after reversing and putting it into first gear, it also seems to run over a rock but much smaller. What the hell is thr problem? Is it the transmission? Axle? Tires too big? Am i putting too much clutch? I brought it to the place i bought and they said its something all manual cars do. Need to know what's happening. I have around a 20 days for the lemon law. Let me know please.

The lemon law is for new cars. Yours won't qualify. I've had several manual cars and haven't experienced anything like that. My only thought is if it has a locked rear end (positraction) that might cause those symptoms. Have a transmission shop check it. If it doesn't happen when you take off straight then I suspect it has to do with the rear end.

EDIT: If you say so; federal lemon laws generally cover only new vehicle purchases. But there's one major exception: if the owner has received an express written warranty along with the used vehicle, then federal lemon law will likely cover the used car.

EDIT: In one your previous posts you're only 15. What state issues a driver's license to a 15 year old?

I'm UNDER LEMON LAW SO DWAI. MY CAR WAS NOT SOLD AS IS.

I've drove manuals for over 52 yrs., and more than 6 million miles, and i've never felt like i was driving over a rock… When going in reverse or forward., i have no idea what you mean when your saying this. EXPLAIN

Sounds like the limited slip is binding up a little. If that's the case then it's normal. Also I don't think you understand what a lemon law is. In order invoke the lemon law, the car has be brought in for the same problem x number of times in certain time frame. You can't invoke it for a single problem that the dealer hasn't had chance to rectify. Some dealers may have a return policy, but that's not a law.

Let another driver test your car.
