Turned out, it was the tires. I had a defected tire from GoodYear. What happened was that my tire tread was moving from side to side (not straight) thus causing the steering to shake at higher speed. My tread was actually 1 inch off~!

anyway, just want to let you other TLers to know

Wish my vibration was that simple to solve. I think mine may be a bent rim. Still pending investigation. I dont want to spend big $$ on a new rim and not be the culprit.

Congrats on getting your problem fixed, man!

 

Wow! 1 inch off is a lot on a set of tires. Glad it didn't blow out and cause you to wreck.
