After 3 week's in the shop because Polaris shipped one wrong length axle I finally picked my XP up yesterday. No more clicking noise coming from the rear and it run's even better then before. Front end look's OK but mechanic will go ahead and change out the knuckles and ball joint's later when they come in just as a precaution. Also had them put on wheel spacer's in the rear for more clearance for the XTR's vs. the swaybar. After 6 inches of rain yesterday we have a lot of mud to go try it in later!!
