any help with this would be greatly taken and used. i have a binding or slipping when ever i take off from a dead stop and turn the front wheels. the back wheels fell like they are trying to hop or catch. if i take off striaght it perfect and there is no problem it i am already going just if i take off from a dead stop. i have had the front end checked and it is all in good shape so i know its in the rear but dont know where to start. thanks josh  

Does this truck have a LSD diff in it? (Posi)  

does it happen everytime? i had a similar problem on my 2002 f150. an ignition coil burnt out on it and i was having a similar problem. when you drive does your rpm gauge bounce up and down or does it just accelerate normally with the truck?  

I have a 03 f-150 that is doing the same thing did you ever find out the problem
