F-53s will not track very well unless the toe-in is set correctly. Loose front end parts also contribute to wander. If the grease boy doesn't understand that kingpins need grease, those will wear quickly. When the toe-in is set properly, tires will wear on the outer edge a little (generally enough to necessitate replacing the front tires before the rear). The price of admission for big truck tracking straight. Front end techs that aren't familiar with long chassis with straight axle adjustment will try taking off some of the toe-in to help with the tire wear. Boom. Wandering motorhome.
So, what's your recomendation for toe setting on the F53? Factory says ZERO. I believe in a little toe but hesitate to change from the recommendation. It's also set where a reputable chassis shop put it, changed from 1/8" IN to 0. They found no problems with the chassis, as far as wear goes. This did not seem to change the "wander" I have now, and before the alignment; even in calm, smooth surface conditions. I do not believe it is me doing it with steering corrections, as some suggest. Been driving for a lot of years and think I recognize an alignment issue when I encounter it.
