I have a 1998 F150 5.4 4x4 that my dad just put a leveling kit on. I don't remember the size of it, but we put torsion keys on the front and blocks on the rear. Anyway, my dad and I put them on and now the front right CV axle is binding. My dad's employee said his girlfriend's truck did the same thing. Has anyone else had this problem or any idea what it might be? My dad has been a mechanic for 25+ years. It's got him all in a pickle. Please help!
