Jack up so the wheel is off the ground, Grasp wheel top and bottom and try to rock, any play will be in the wheel bearing.
Grasp wheel at front and back and try to rock, any play here will be in steering components. Lastly turn wheel or get someone else to do it whilst looking for movement in the U/J.
You can drop the wheel back down and get a friend to rock the steering wheel side to side whilst you look at or put your hand on all the joints to see/feel any movement.
Good luck
