Axles, Which Ones & From Where?

I soon plan to replace the "rear axles" in the 2005 Sportsman 400, as they have started to "click" from time to time when starting out in either forward or reverse motion.

Note: This machine does not get used hard, does not have large tires, nor does it have the power to twist off an axle….. so the heavy duty models aren’t required. :yaya:

With that said…. what would be the "BEST" and most "REASONABLY PRICED" OEM or Aftermarket axles I should go with?? :ditsch:

Please list brands and links to the best prices people have found…

THANKS!
