1. A suspension system for a washing machine, the system comprising:
a frame member defining a joint recess having a curved profile, the joint recess defining a rod opening; a suspension rod including an upper end configured to be inserted through the rod opening; and a ball joint configured to vertically support the suspension rod relative to the frame member, the ball joint comprising:
a joint body including a lower portion configured to be seated within the joint recess and an upper portion opposite the lower portion, the lower portion defining an outer surface having a curved profile generally corresponding to the curved profile of the joint recess, the joint body defining at least one lubrication inlet port extending between the upper and lower portions and at least one lubrication channel extending circumferentially around at least a portion of the lower portion along the outer surface, wherein the at least one lubrication inlet port is in fluid communication with the at least one lubrication channel such that, when a lubricant is injected into the at least one lubrication inlet port at the upper portion of the joint body, the lubricant flows from the at least one lubrication inlet port into the at least one lubrication channel and then flows circumferentially within the at least one lubrication channel along the outer surface so as to lubricate an interface defined between the joint recess and the lower portion of the joint body. |
