How to Dolly Tow Unlockable Sterring Wheel Car

The OP said he had the alignment checked, Did they check the alignment on the rear axel? Vehicles that are front wheel drive must have the rear aligned. I am not familiar with the vehicle but if its an independent rear it definitely needs to be aligned and if its a straight axel something is bent. Its like pulling a wagon, the rear wheels will follow the front unless something is wrong with the rear wheels.
