This is a break-away piece to the outstanding editorial done by Harvard in 2011, in which he discusses the issues dealing with too little caster in e350/e450 vehicles. If he is still around, and might respond, I would appreciate it, or someone else with intimate knowledge of this issue. When he mentioned that he did adjusted the caster while in an Arizona campground, but later in his piece he stated he had no way of checking caster, how did he know what caster setting he had to begin with, and how would he know what his starting point was? Also, I would like to know if a truck front wheel alignment shop does that does wheel alignments will adjusts the caster as part of the process of aligning the front wheels. Finally, should i let the wheel alignment shop take care of ordering the Ingalls 594 camber/caster sleeve, and is this required for the actual wheel alignment process, or only when adjusting the caster? Thx.
