Re: Front Tire Wear
More wear on the outside of BOTH front tires usually means too much toe-in. Easily fixed by turning both tie-rod adjusting sleeves to move both wheels leading edge out a bit. Could try one turn each, then watch over time to see if you need more. Turn both sleeves the same amount, so your steering wheel centering is not affected. Mark sleeves with chalk first, so you know where you were. Been doing this for years on all sorts of vehicles.
I am assuming that you don't have a camber on both sides problem, caused by front spring spacers added, or new coils that are tall or something like that, since these are swing axles, they move in an arc, not in a parallelogram like A-arm suspensions!
