I have a 99 F350 with the 7.3 diesel. The truck has 245k on it. The problem I have is there is play in the steering wheel. I have to turn the wheel about an eighth of a turn in either direction to get the wheels to respond. So in other words I can turn the steering wheel from about 10 o'clock to 2 o'clock without the front wheels responding.

Can you guys please point me in the right direction as to what I should start looking at first? I will go tug on any parts of the steering shaft I can reach and see if theres any play, but I'm wondering if theres any adjustments I can make. I appreciate any help.
