Hopefully this helps people understand what the "clicky axle" problem in the 350z is. Most of this I've not written myself but pieced together passages from various places to make something relevant to the 350z. Before I had my own clicky axles repair I had hoped to get a sound recording of it to add, if someone could do this it would be much appreciated and could be added into this post.
Something worth noting is that "clicky axles" shouldn't be confused with a "clunk" from the ARB drop links. These two sound different, the "clicky axles" are a higher pitched clicking like steel ball bearings or marbles rolling around hitting together while the ARB drop link "clunk" normally sounds like a shift in two mechanical components past each other transmitted through the chassis to sound like a "clunk".
