I own a 2015 TRX420FA5. Less than 20 hours and I tore a boot on the outer rear right. I was able to put the boot back on. I replaced the boot a week later. It now has an audible click when backing up and turning right. Apparently, I had a small rock in the cv joint which I failed to clear when I replaced boot and repacked grease. It is not covered by warranty. Any suggestions on new rr axles? I appreciate any useful advice.
