Had the vibration before tires, rotors, pads, steering rods, and a couple less gray hairs

Oh, NOW I see that in your first post. Sorry...

Hey lash,
I know what a 180 t-stat is but what is drilled?

For us in hotter states, the drilling is done to help keep some coolant flow at all times and help reduce the potential for heat related damage to our 3800s (I.E. UIM and LIM failures).

Here'* a really good thread that talks about it and also includes some links to TechInfo and other good threads:

180* Drilled Thermostat

Ok, the Gabriels go back to Autozone. Which Monroe'* are best?

Reflex is best. Sensatrac is next. Be warned that you may have an imbalance if you only do the fronts. Try it for awhile.
