2016 XP1000 Rear End Noise

Just wanting to know if anyone else has had this problem, unloaded off trailer this morning and started riding and started hearing popping noise in the rear. Does it when turning front wheels to right or left. One of my friends grabbed the right rear axle and it looks and feels like it’s moving in and out of rear end. It only has 81 miles and this was the 4th time I’ve taken it out. Loaded it back up on trailer and heading to dealership in the morning, kinda wanting to know what to expect. Thanks in advance for any information
