Which direction is the play, hand on top pushing forward and other hand on bottom of the wheel pulling towards you, rock it back and forth and see if you have movement(this would be balljoints, king pins, trunnion movement.
Move your hands to the sides(9 oclock and 3oclock position) and shake the wheel side to side(this would be tie rod end, steering linkage movement. If the wheel moves in both direction and when you put your hands at 10 and 4, rocking it then it would be wheel bearings, spindle movement. Just how much is "a little"? Ideally there should be none, but I've had slight trunnion movement on the 75 TR6 for over 3 years and no problem.
