The problem occurs between 35-40mph, it may be occurring outside that range, but I can't feel it. As for the vibration, it is in the front of the car, and through the steering wheel. The steering wheel shakes with the front end. You can see the entire front nose clip shake from side to side. Most of the steering components are new. Pitman Arm, and centerlink are originals. Also I'm using a new Steering box a newer fast ratio box.
I'll be looking for tires over the next week or two, I'm going to be doing some traveling so I'll be a bit busy. As soon as I get a chance to swap, I will and I'll let y'all know if the problem still exists.
