My 2002 2500 4x4 LB EC has the usual wandering problems apparently aggrevated by The big Rixon wheels and tires (are they still in business?). I tried the Luke's link tracking bar fix, Borgeson shaft and positive camber. It still has to be "driven" all the time or you end up in the grass or median (depending on the crown). SSI's track bar and steering box gizmos (see TDR 46 p 154) look like an answer BUT I'd like to hear more than one opinion. thanks, Larry
