Bad Vibrations

Hello everyone! My steering wheel strongly vibrates left and right in small, jerky movements at speeds over 55 mph. It does this especially on turns, but once in a while also on straight roads. Also, occasionally I will feel a deep vibrational "thrum" in the steering column. Can anyone give me some ideas as to the potential nature of this problem? Thanks in advance for any info!

MTN,

It's most likely a belt seperation or out of balance problem, either
way you should get it checked out SOON.
Welcome & good luck,

Thanks Ldub, I'll get it checked out immediately.
