Front end? Tires? Shocks?

[Bo Loo]

Up till about a month ago, the ST was driving smooth and straight. With no accidents or anything else I can imagine that would cause problems, here's what's happening:



Around 35 mph, the steering wheel will "shimmy" slightly back and forth.



Around 45 mph, I hear a low "humming" sound which increases with a slight turn of the steering wheel. Straighten the wheel and the sound decreases.



To my untrained eye, the tires look good and have a very good amount of tread left.



It's not pulling to the left or right that I can recall....



Ideas?

Tires cupping and out of balance.... Rotate and ballance the tires and go from there...



ALSO make sure the tire pressure is good before ballancing...

If not the tires. Take a look at the tie rod ends. Inner and outer..
