Are you running aftermarket rims? If so, and even if you aren't, certain places are better at balancing wheels/tyres than your dealer.
My brother in law bought a Durango with dealer installed 20s, he took it to the dealer with this exact complaint, they couldn't fix it.
A few minutes at a real aftermarket wheel place and he's shimmy free.
