The vehicle makes a buzzing sound and vibration you can feel in the steering column. It occurs at speeds over thirty five mph. The vibration goes away when wheel is turning the steering wheel a few degrees to the left.

Those are the classic symptoms of a noisy front wheel bearing. Usually it is the left one because weight comes off of it when turning slightly to the left, but with bolt-on bearing and hub assemblies, that can be misleading. Sometimes the other one is bad and the noise gets transmitted to the other side of the car.

Noisy bearings are rarely felt in the steering wheel. A better suspect for that is a broken belt in a tire.

Thank you for the comments. Unfortunately I already replaced the wheel bearings. The tires are less than a year old, but I might bring it back to the shop to have them checked out.

I had one mechanic suggest that possibly it could be a drive shaft bearing. I do not know to much about that and when I have looked up symptoms of that type of problem, is commonly associated with crunchy sounds upon acceleration and I have no such symptom.

Still in the dark. Illumination welcome.

Defiantly get the tires and rims re checked. also, get all steering and suspension looked at as well, there are many things that can cause this type of vibration, but tires and rims are the main culprit.
