There's a clicking sound when I turn the.

There's a clicking sound when I turn the steering wheel far to the left, it only happens when the steering wheel is turned all the way to the left or near it, and happens with less intensity when making a similar far turn to the right. The clicking is rapid and the rate seems to be dependent on the speed of the car.

Also on the highway when the car travels faster than 60mph, I can feel a fast vibrating shake in the steering wheel, its subtle and not too intense, but increases with intensity with speed, it scares me to the point where I won't drive this car faster than 60 mph.

The car has snow tires also, and I just bought it used.

Thanks for any input,
