I'm thinking "get new tires" is the answer. My 2002 Trooper pulls to the right. On a flat, level road, you have to hold the wheel cocked slightly to the left of center to go straight. I know a bit about cars and alignment. This prob has nothing to do w/the brakes; i.e. it pulls to one side while braking. This happens when just driving or coasting. I've had it checked out by two different alignment shops (the first one the Isuzu dealer sent me to since they don't have an in-house alignment rack). Both place told me that all the specs are dead-on factory settings and that the problem is being caused by a tire defect called "radial pull." WTH does that mean? There's nothing physically wrong w/the tires, as far as I know...I keep them properly inflated and rotate them every 6K miles.
