Help! Love my truck, but

Anybody got a clue whats happening to my truck? It feels like the brake is *slightly* on all the time and there is a minor shimmy in the steering wheel. The shimmy used to be worse, but the dealer changed the tire pressure and it's better. (I first tried solving it by getting new tires).He said he could not locate the origin of the problem.

What year is your Tundra?

Does the brake shimmy get worse as you apply the brakes? The Tundra had front brake problems, epsecially the 2000-02's, because the front rotors were not large enough. You may have a warped rotor.
