A Study of Durability Problems and Solutions for Vehicle Hub Bearing 2007-01-0633

Noise from hub-bearings of used vehicles originates from various sources as the seal, capacity, shape of related parts, lot characteristics, production quality, test method, and lack of tightening torque. To investigate the effect of each source on the durability of hub-bearings, used cars as well as part and actual car's accelerated durability tests are performed. In this investigation, load conditions around the hub in various field conditions are analyzed, followed by the improvement of ideal life-cycle equation and part durability test procedure. A new process including design, test, quality and production guidelines are suggested for hub-bearing durability improvement.
