Spacer lift kit

It is wise to do while doing a lift since stuff is already mostly apart but just pointing out failed in my mind is extreme until pieces start coming out on their own. This is my axle after idk how many miles (maybe 5k? Bad memory i blame the ) Note shiny spots where axle was able to wiggle inside needle bearing and begin to wear due to excess play. Been 10kish miles since install and smooth as butter and tight as well its very tight.
