US Patent 11754119 Apparatus for preloading a bearing

A method for preloading a bearing includes releasably, threadably, and directly attaching an attaching member to a circumferential outside surface of an exposed end of a threaded shaft of an axle or spindle. A frame is axially separated from, and coupled to, the attaching member. A plurality of extensions extends from the frame axially past the attaching member toward the wheel hub assembly. An adjustment mechanism moves the frame and the plurality of extensions axially towards the wheel hub assembly to contact the wheel hub assembly and/or the bearing to apply a preload to the bearing within the wheel hub assembly.
