Could it be warped brake rotors? On a once owned and quickly dumped '99 Jeep GC Ltd, the brake rotors warped w/in 7k miles, enough so that the steering was effected even when not braking. That vehicle was a traffic hazard. Convinced me to never buy 'Domestic' again... Love those Tundras! Please don't bum out my ride... just ordered an '05 DC 4x4, and am trading up from the Access Cab. Mistake?
