Yes, technically they can, in a classroom (cough), but they don't.....They can "vibrate" if they are moving around in their sockets but it's always something else causing the abnormal vibration or shimmy.
Shimmy is an "abnormal vibration"
Shows how much you know.

If you are trying to diagnose a vibrating component on a vehicle, the vibration (low frequency) is most commonly caused by wheels or tires. Steering wheel shimmy (sideto-side movement of the steering wheel) is always caused by tire/wheel imbalance. Low power steering rack friction can also amplify the steering shimmy response to imbalance. Normally the vehicle will show very low steering effort when compared to a known good vehicle.
Vehicle shake (up-and-down movement of the steering wheel) can occur with balanced, non-factory tires and wheels. Tire shake and shimmy will vary with changes in vehicle speed. Speed sensitive vibrations are usually due to an out-of-balance wheel. It is also possible for tire shake to occur ONLY during braking. First-order tire/wheel vibrations usually produce a vibration frequency of 10-20 Hz.
