I am hearing the click, click, click from my RF CV joint, so it's time to upgrade to Chromemoly axels. The Rhinos are 1/2 the price and made from the same material. The cages are different, as Rhinos are stock configuration and Gorillas are of their own design. Can any one who has used either give input as to why they would choose one over the other? I believe the Rhinos are available from Super ATV, which is a supporting vendor, do I get a discount from them? Is there a coupon?
