Hey need some insight on a problem with my 2010 expedition El. 5.4 two wheel drive. I was getting crazy grinding noises from front brakes when driving from a stop and low speed Accelerations. Read where putting the vehicle in Tow/haul mode would help determine the problem if the noises stopped while in that mode and they did stop. However now when I put it in reverse I get an even louder grinding and I'm pretty sure it's on all 4 whls that way, it doesn't happen until tapping the brakes and continues after brakes are released until its in drive. Really want to fix this as it sounds like it could be very expensive if I don't soon?
