Toe will not cause a pull, just eat tires and possibly set the steeringwheel off from center. A bad CV axle can cause trouble like that depending on how bad it is. You should definitely check your suspension and make sure nothing like a lower control arm bushing has worn out. Have your engine/trans mounts checked too. They way they position the engine, they keep your engine/trans from creating torque steer on acceleration but it could also cause some weird stuff on decel if the thing decides to get itself twisted a bit weird.
