A shaking steering wheel can be a sign of improper alignment, but there are other, more common causes of the potential problem. If you feel a vibration in your steering, you may be overdue a tire balancing, or you might have problems with your suspension or brake system. That said, improper alignment is a common reason for your steering wheel vibrating or feeling “off” when driving. If you notice this, having your car checked out by a professional as soon as possible is a good idea.
