What does a broken tie rod end do to your car?

It wouldn't be calm and quit I'll tell you that much. If it has/will break or you think it will break, do not drive it. If it happens to break while you are on the road you will almost have no control of your vehicle. The wheel may decide to go left or right on its own,the best priority is to stay calm and do NOT slam on the breaks,this could lead to the car to lose control or even possibly roll.
