Designed for use on Lippert trailer axles commonly found on RV travel trailers, utility trailers, and other towable applications, this spindle nut kit simplifies hub service and bearing repacks. Proper installation torque is 18–22 inch-pounds while rotating the hub, with no end play once correctly seated. Replacement of spindle hardware is recommended during any hub rebuild or bearing replacement service.
