Steering wheel shakes
Assuming that one is referring to a front wheel alignment, there are a number of signs that can indicate that this process is required. If the car has driven over 100,000 miles since the last alignment, the front tires are wearing unevenly, the front of the car shakes when driving on a smooth surface, or the car is pulling to one side, a front wheel alignment is probably needed.

Uneven tire wear. If the car "pulls" to one side or the other. If the steering wheel is not lined up properly when the car is pointed straight ahead.. BBA
A wheel alignment is what syncs your steering wheel with your wheels. It ensures your car will drive straight when your steering wheel isn't turned.

you need a whell alignment
The only that I know of is that you need an alignment.
I just took my all wheel drive Subaru to Town Faire Tire today. Before the service man knew my car was an all wheel drive, he explained about alignments and said that all wheel drive cars often need alignment more frequently. At 12,000 the print out figures showed that my car needed one.

if the the car has never had an alignment, do that first and have the shop check rear wheels for tracking, they can adjust if required
At least every 30,000 miles. If you let go of the wheel and your car veeres right or left. If you drive and your car and your steering wheel shakes, its not an alignment you need, you need your tires balanced
Sounds like your car might need either an alignment or the wheels have to be balanced.
