For about a year I had this buzzing sound. Kind of like someone put a bunch of playing cards in the spokes of a bike. And it came from my front left wheel. After my truck shot a wheel bearing and the dealership told me I could have lost the whole hub I decided to take little noises more seriously and dug out my front wheel bearings. Bought a great kit off Ebay that swapped the regular stock bearings for a cone and roller system which, since I work on Attack Helicopters in the Army, I know they work well. Thats what our wheels use.
The stock bearings were worn down to flat, filled with sand and little pebbles. The seals looked great but obviously were not. And the grease turned to a paste. If you have been sinking your quad in mud be sure to repack your carrier and wheel bearings. Next im looking at repacking my swingarm bolt if its in good shape. But all the work ive done on my quad lately im amazed at what ive been riding on. And how easy it could have been fixed before the bearings wore flat.
Just putting it out there to check your stuff, I didnt, so who knows who else hasnt either.
