HUB ASSY., 545 SM EZ ID KIT

This is a trailer idler hub assembly kit designed for a 3,500 lb axle. It is an E-Z Lube style hub, which means it has a grease fitting accessible through the hub cap to make bearing lubrication simple without taking the hub apart. The kit includes the hub, bearings, races, seal, grease cap, and lug nuts, so you have everything to replace a worn or damaged hub on your trailer. You would typically replace this if your existing hub is damaged, has a bearing failure, or if you are doing a complete axle end rebuild.
