Help me with this steering issue!

[dirtracer81_2]

Ok I have a 99 f250 4wd superduty. When I drive it down the road it likes to wander some and when you go around a curve it feels as if its still wanting to turn when you start to straighten back out. You can go down a straight stretch and wiggle the wheel and can definately see theres a little play somewhere. When its sitting in the yard with my dad shaking the wheel it has very little to no play. If I jack one side up and try to move the wheel to check the tie rod ends it really tight. Ball joints seem tight with a 7 foot bar. The track bar bushings look as if they may have a little bit of play but nothing major....Any pointers on solving this problem I have?
Thanks

look at the shaft coming out of the gear box good , see how much gear box play you have

From what I can tell about the same steering is being transfered out of the box. Im going to try that link on the pitman arm.

I had the same problem everything was tight but drove like **** so i put a steering stabilizer on that help but still drove bad so i broke down and bought a steering box that solved the problem drives great now.The box listed for around 265 and i got it for 209 from my ford dealer be sure and take your serial # it was easy to change other than getting the pitman arm off of box. i removed air box,battery and tube going to after cooler u may end up haveing to buy the 2 hoses that go to the steering box to get them to reaseal
