Troubleshooting sounds from rear suspension/drive

I recently bought an Outlaw 525 IRS. The people I bought it from let the suspension out as much as possible so they could lower it…I know I know.

I reset the suspension to my weight, according to the service manual. When I did this I took it for a test right and immediately noticed a loud noise coming from the rear of the bike, especially when I turn (left or right). The noise is a loud clicking, the noise increases in speed as the atv increases in speed. It also does this whether it’s going forward or in reverse, again mainly in a turn. I lowered the bike back down where they had it and the noise goes away.

I’m thinking that it’s the CV joints because when I raised the bike back up it increases the angle of the axles which could put more pressure on them. I’ve been told it could be wheel bearings or the center carrier bearings. Also the inside or outside CV joints. So my big question is how do I troubleshoot it down to the problem? I don’t want to throw money at something that doesn’t need to be replaced if I don’t need to.

Also it may need to be noted that the rear upper a-arm bushings are worn out and need to be replaced, they’ve been ordered already. I also replaced the chain (I know that’s not it but figured I’d still mention it.
