Hello,
I recently bought a 2005 f150,i dident realize untill I bought it that there was a grinding, vibration coming from what sounds like my differential when I turn at low speeds, I thought someone may have put the wrong oil in it so I cleaned it out, added a tube of friction modifier and synthetic 75 w 140, and still have this problem, I have a pic of it with the pumpkin cover off if that helps. I cant figure out what it is, this truck was in fender bender before I bought it and has some steering problem (veering heavily when let go of wheel) could that have anything to do with this? Anything helps thanks
