I ended up finding out the issue my style axle is a FA 617 I need a faw617, I bought another dm cut off with 425s on it and the axle itself is a couple inches wider than the current

i have a 1985 mack dm686s i bought the truck and it came with the narrow street tires on the front axle, i changed them out to dayton 425 65 22.5 and they rub very bad on the pitman arm. other dms i have driven have 425s and they stick out 3-4 inches past the fenders mine do not. i was told mack offered two different axle widths for these i have the narrow, does anyone have the part number for the wider style axle 18k
