Intermittent whine ’02 Grizzly

Hey guys I’m brand new to the forum. I have a couple of issues with a 2002 Grizzly 660 that I’ve recently purchased. The first one is a new noise that I’ve just started hearing after a buddy replaced the rear bearings. I had them replaced because he thought it would fix the clicking sound that my Grizz makes on sharp turns in forward and reverse. New bearings did not remedy situation but did introduce another possible issue. Below is a link to a video. You can hear the noise I’m talking about pretty well. Any ideas on potential issue and fixes would be greatly appreciated.
Thanks in advance!
David
