Greetings, my KUDS24SEAL5 was not cleaning very well. I noticed the lower spray arm was VERY wobbly. It spins freely, but is VERY wobbly. Yesterday, I replaced the washer arm bearing (WP9742946) which was worn paper thin. I also replaced the split ring bearing (WP3376846) on the bottom of the spray arm as well. Though not part of this discussion, I replaced the split ring bearing on the upper washer arm as well. I have only run one small load since, and it appears to clean better. Too early to tell at this point. One thing that bothers me is that even after replacement of the lower washer arm bearings, the spray arm was VERY still wobbly. I didn't expect it to be. The spray arm has what I would estimate to be 1/8" - 3/16" axial play if I pull directly up on the spray arm. How wobbly should this spray arm be? Is there a clearance spec for it? Could the flange on the spray arm nut be worn so much to allow this wobble, or is the wobble normal? It doesn't look worn at all. Thanks.
