On mine the front axle is disengaging. When i make tight turns in 2wd high it turns normal when i make tight turns in 4wd i can feel the front axle is engaged and making it harder to turn and a little jurky.

 

jbrew and kingfish51 thanks for the tips. I will take a look into what both of you where saying i dont know too much about how the 4x4 works on my truck except the basics. I wont be able to do it till Oct. thougt cause i am deployed in guam right now. But when i get back could you too just keep an eye on this topic so if i have any questions
Thanks
CJ
