The other night i was driving home and i didnt see a turn coming so i stepped on the breaks hard and there was a stop sign ahead. So when i was breaking i was turning the wheel slighty so i wouldnt hit the curb at the same time so, now my steering is kind of stiff and when i'm going straight and i turn the wheel it immediately goes back straight. I thought i didnt have any power steering fluid so i checked it was kind of low so put more in. And it still stiff anyone know why it is happening?
