You mean while driving? Unbalanced wheels, bent rims, etc, cause vibrations in the steering wheel.

Do all they have to be driving? If not then a misfiring cylinder can cause a vibration at idle. Or a big cam can always cause a little shaking
Warped brake rotors will cause shaking when braking. Rough Road |

A car with screwy cylinder deactivation will shudder a bit.
Same with cars with engine start/stop hybrid tech.

Vibration when slowing down is the rotors and if the lugnuts aren't tight and good, it'll shake as well.
Those are the only experiences I've had with a shaky wheel.

A tick over 13.0 sec. and you're through the quarter-mile. It's a rush, of course, but not overly dramatic. Try the same thing with this pair's predecessors of 1970 or so and you'll find yourself in a bit of a wrestling match. Ain't progress wonderful? Maybe yes, and maybe sometimes it's fun to wrestle."
