This component secures the inner wash drum or basket to the gearbox drive shaft and helps ensure that the drum rotates correctly during washing and spinning.

Important Fitment Note

LG top loader washing machines may use different hub nuts depending on the gearbox, drum hub and production run. Before ordering, compare the OEM number, thread diameter, thread pitch, nut height and overall dimensions with the original component.

A replacement hub nut will not repair a stripped gearbox shaft, damaged threads or a worn inner drum hub. Inspect the gearbox shaft, drum hub and splines before installing the new nut, and tighten it according to the correct appliance service procedure.
