My 2004 F150 FX4 has a vibration in the front end. I feel it in the accelerator pedal. When I am driving strait or turning left it is there but to the left it stops. I have changed my cv’s and locking hubs along with the locking hub sensor. Plus the brake rotors and had the tires Balanced and rotated no change.
So many possibilities if vehicle has seen hard off road use (such as worn tie rod ends. Bite the bullet and see a suspension expert.Correct diagnosis will save you replacing parts that do not need to be.As you can replace C.V.s you are obviously competent.Proffesional diagnosis + your labour saves time and money.Good luck mike western australia
