Could this be the answer to steering wheel play?

update on my steering wheel play. After many minutes of staring at the u-joint and steering shaft I discovered that the freakin u-joint to shaft bolt was installed the wrong way which is why it wouldn't squeeze and lock into the shaft. Only one end has thread in the hole so that is why it would still tighten but not lock into it. I have yet to test drive but it seems to have solved the looseness in that connection. My cousin helped install the shaft last week(he was under the dash) but I think the bolt was put in wrong long before that because that has been a problem since I bought the car.
