My wife's pacifica started shaking when on the high way and doing over 60MPH. below that, its fine. anyone experience this ? i took it into the shop to check it out, hopefully its just the "service tire system".

"Service Tire System" ? Meaning there's a light on that says that? That's the tire pressure monitoring system and that means the pressure in your tires is too low - and that causes more wear AND the tire is more prone to irregular wear, which can cause a vibration - and you generally feel tire related vibrations between 50 mph and 70 mph.
I should also mention that mis-alignment will also cause irregular wear.
You can fix the alignment and the tire pressure, but you can not put rubber back onto the tire, so perform a rotation, and if the problem goes away, consider yourself lucky.
If the problem doesn't go away, you can either live with the vibration (it will probably get worse) and closely monitor the tire wear (it will probably wear much more quickly) or get new tires.

I have the same year and model and had the same problem (among many others!) I recently had my tie rods replaced and got new tires and the problem was pretty much resolved. I think it was more of a problem with the tie rods, as I had my old tires balanced and rotated and still had the issue. My shake would happen at exactly 62 miles per hour.
