I have a 13 xp 900 with 1700 miles. Noticed some clacking coming from the rear end so I took it to the local cycle shop and he said the splines in the axles were starting to wear. He packed them with grease and said it might last a while or might not last long at all. So I did some searching and noticed it’s a pretty common thing. I’m just curious how long everybody waited to get new axles or jus keep a clacking…….
