Hey fellas i bought a 2011 xtz 1000. Been loving it so far. Airdam stage 2 clutch, commander v, and dual muzzy's. Its loud and fast! It has 800 miles on it, only one issue, when i start to reverse it sounds like front brake shoes dragging, i took a better look and i think its actually wheel bearings, the noise is coming from where the axle goes thru the spindle. Is this normal? I sprayed some grease in the opening behind the cv boot and the noise stopped so i'm thinking hub bearings. Am i wrong?
