I posted not too long ago about my front end shaking pretty good at 55mph (not dw). Well I decided to rotate my tires yesterday and voila! party1: The shake is completely gone away. So im guessing that one of the front tires either has a bent rim, or unbalanced. And now that there on the rear it dosnt show up. Just thought I would share this so if anyone has the same problem...rotate those tires first. It may just save you some time/money.
