When was the last time you had your wheels balanced thats probly your problem. While your at it get an alignment too. And if that dosent work your driveshaft could be out of balance ive done that before.

Honest,
hate me.
You may have hit a curb and moved balance weight!
I discovered MY WIFE DID THAT ALOT!!! Tires showed it!
Spend the effort, rotate, see if it'sinthe front or the rear. Then the shimmy test, steering wheel. Or look at the tires, yo may see what's happening, easily.
How's the Temp gauge situation, Chad, Solved??
