Tester is 100% correct. This vehicle is not safe to drive in its current state. Until you have the money available for it to be inspected and repaired, park it and do not drive it. As Tester stated, it could be as simple as a bent wheel, or it could involve damaged tie rods or other front-end components.
No matter what the cause may be, this car is not safe for you, for your potential passengers, or for anyone driving near you when something finally gives and you have no ability to steer the car.
