Decided to tackle this today. Previously had this problem on my '06 Infiniti G35 coupe. Back then, I took the regrease and rotate 180 degrees route and didn't have any additional issues. So, I'm considering this preventative maintenance. I also like that the axle nut is black (also comes in plain stainless steel). For those like me with aftermarket wheels without center caps, it is more asthetically pleasing than the crappy OEM adjusting cap.
This method seems more durable. I had trouble sourcing the Kawasaki nut so I found an equivalent at ProBolt-USA.com. I did need (3) spring washers per side to position the axle nut correctly to be secured by the cotter pin.

Nissan cotter pin 00921-5402A (Qty=2)
Pro-Bolt M24x1.50 Stainless Steel Axle Nut Black LSSNUT24150001Z2BK(Qty=2)
Since I have a '17 and the rear axle click has not yet presented, I didn't feel the need to regrease with the M77 moly paste.
