'05 F150 5.4 Sounds like a whinning noise from the front end when turning to the right or going straight. Goes away on left turns. Thought it was tire whine but put originals back on and got same thing. 13.5x35 verses 275 Truck has a Fabtech 6" lift. Right CV axle seems tight, rotor assembly replace 2k miles ago. Any suggestions before going into front diff?

 

Let me know if you figure it out. I've got the same peoblem on my 06 F150 2WD. I'll let you know if a solve it.

 

turned out to be the left hub assembly but I don't think they are the same in a two wheel drive. Maybe I forgot to say mine was 4x4
