Front end wobble.

Dana67dart has it right with the toe in or out scenario I would almost guarantee it is alignment. Does the steering wheel wobble at quick acceleration,but go away when accelerating slowly. Problem is that one tire is pulling one way while the other is trying to turn the opposite way. At faster acceleration or high speeds there is less weight on the front of the car causing the tires to fight each other. Both tires are trying to go straight causing the steering wheel to go into what they call a death wobble. Not fun. First instinct is to hit the brakes slowing down the car adding weight and temporarily fixing it. At slow acceleration with full weight on the car the tires will balance each other out but will wear the rubber down to cords in just a few hundred miles because they are still fighting. Had it happen in my 37 hotrod. Hit a smooth rubber patch at a railroad track, car pulled right as passenger tire gripped pulled steering wheel through my grip and I almost rolled the car. When I checked tires with a tape measure. Front to front rear of tire to rear they where out over an inch. If the bushings and ball joints,and tierod ends need to be replaced. Do it, or the alignment shop wont be able to properly align it any way.
