Preload Adjustment of Wheel Bearings on Tractor Trailer Combinations - Latest Developments

This technical paper follows a series of four previous SAE Technical Papers dealing with progress of wheel bearing adjustment on tractor/trailer combination vehicles. Since 1995 there has been increased attention devoted to improvement of wheel retention due to the high incidence of highway accidents caused by “lost wheels”. This presentation will supplement the information provided in the earlier papers by discussing the efforts performed by various activities during the past several years. In addition, the attempt will be made to further stimulate highway safety by projecting the course of future activities.
