rzr 900 4 2015 REAR AXLE

here the video of my rzr 900 4 2015 with strange noise coming from the rear axle ( second 04 and second 20) and which is heard from 0 hours of use, already in service where you are also checking the noise and vibration of the axle front and only has four hours of use, I inform you in a few days I spend with the guarantee and solutions

if someone had that noise would appreciate help to know why you do that if I fix it already

greetings
