overdrive unit thrust bearing and direct clutch thrust plate
# 518TB / 12860-01K. Sonnax offers a replacement kit for the Chrysler 500 and 518 overdrive unit thrust bearing and direct clutch thrust plate, 1988 on. These plates fail due to direct clutch thrust plate flexing from the spring load. The bearing plate is designed to have the correct taper on the bearing face that flattens out under the load of the overdrive clutch spring. Many aftermarket bearing plates lack this taper and cause the bearing to fail prematurely. The high quality Torrington bearing is the larger, updated OEM version with a much higher load capacity than the earlier OEM bearing.
