Excess tread wear
I am having a problem with excess tread wear on the inside of the left front tire and to a lesser degree on the right front tire on my F-150 tow vehicle. About 20,000 miles on the Goodyear Wrangler. I...

Our E-Series had wear like that when we bought it. Found the front wheels were "Toe-Out" by much more than the specs allow. Turned out the tie rod ends were worn and I eventually replaced them. In the mean, I cranked the adjusting sleeves shorter and got to slight toe-in.
You can check Toe with a Helper, a Tape Measure, and Two Hat Pins. Drive straight on a smooth flat surface and come to a gradual stop. Sight across the tread of the tires behind the axle and stick a Hat Pin into the tread, square with the tread surface. One each side, as high as the truck will allow your tape measure to go across without interference. Measure and record the spacing of the pins. It doesn't matter What the Spacing is, only that you'll compare with another measurement. Drive the truck forward till the pins are forward of the axle, low enough that you can get a straight measurement across the pins. If the front measure is More than the Rear measure, it's Toe Out. If so, I'd suggest you try to work the adjusting sleeves to get Zero (equal spacing between the pins) or a little Toe In. We went from 3/8" Out to 1/8" In. The wear stopped and it tracked better.
