Suspension question.

We took a trip to windrock this weekend, and put over 250 miles on the 900. I noticed that when the suspension was flexing there was a popping noise coming from the front and rear. Has anyone else had this problem? And does anyone think it could be the sway bay end links? I know it’s not a broke axle, definatley had my share of those, but just looking for advice! I’m new to the sxs riding
