Been doing some hard riding and been hearing some creaking and pops. Everything has been greased up the same day as riding. Upon further inspection I noticed that the front and rear cv boots (one front, one rear) were damaged and leaking grease. Could this cause the noises I’m hearing? Would I just be able to replace the boots or do I need new axles? A buddy who has a 1000 thinks I’ll need the new axles. Thanks for your help!
