take both hublocks out of the hubs. You dont even need to take the tire off. Popp the center cap off and take the metal snap ring that holds the hub off. I have found blugening my fingers is easier than using pliars. Once the ring is off, rock the hub up and down and side to side while pulling till it finally pops out. Once the hub is off, go drive it.....see if it still makes the noise
