Steering Wheel Shaking.

Have you done wheel alignments

One of your wheels may be out of balance. Or someone forgot to tighten lug nuts. I'd have it checked out before driving it, may be something simple, or maybe something dangerous.

Time for a complete front end inspection.

Get front end inspected for loose or worn parts, get front end aligned, get tires balanced. Alignment will generally not cause vibration, but suspension parts can and tire out of balance is most probable on the list.
