I had about 400 miles on it, but i do spend alot of time in the mud. But if you haven't greesed them yet take a look at them. the factory ones are not sealed. I bought a greese gun that comes with a needle on it and it workes great for the boots and bearings. I saw on your pics that your from lower Al. We do alot of riding at southern Ridge ATV park when there open. Ever been there?
