at 63 mph the car jerks to the right not hard but enough to get you seasick if you stay above 62 mph?tires are all at the right pressure had wheel alignment new ball joints 6 months ago, same time.any ideas.also what shocks are recommended

 

Jack the front of the car up and test the wheels for any looseness or play
Both in the horizontal and vertical directions
Also check the tie rod ends for play
Are the wheels/tires speed balanced??
