Ford 6.7L Power Stroke Diesel :: 2014 F350 - Grinding Noise And Tire Wear

Ok haven't been on here in a LONG time. Sold my '12 and bought a DRW '14 F350 to tow our fifth wheel. Just got back from a 775 mile round trip pulling our fifth wheel. My dad noticed my passenger front tire was going bald on the outside. I said yeah it was pulling to the right and thought my tire was low but when I checked it was the right psi.

Turning to the left I was starting to get a grinding type noise. If I rolled my passenger window down you could here something just grinding away but when you straightened out nothing.

So I took it into the dealer and they tell me the outside tire wear is normal. I said it has 22,000 miles and the passenger tire will be bald on the outside in 4,000 more miles or less. Said they can't hear any noise, yet my wife can hear it, kids can hear it and people outside the truck can.

It's not normal for the passenger or drivers tire for that matter to go bald in less than 25,000 miles? Tires have always been kept to proper psi, I've towed only about 5,000 miles total with it. They are also taking the worthless rancho rebranded shocks off and going with bilstiens. I should have replaced them 10,000 miles ago. They are horrible shocks.

It really torques me that they have it for a week and can't find anything wrong. When turning to the left it's almost like bump steer in 4wd just not quite as bad but with also a grinding sound that you can hear inside the cab and can feel it in the floor board. Nothing evident but just looking under the truck.
