Good job. First its not a gasket its a seal. Next you need to remove the spindle from the knuckle. That's held on by the 6 bolts. Then we can walk you through the next step. Before you do the rest get a proper parts washer. It only needs to be an old canning kettle or metal wash pail and a parts cleaner brush and a gallon of diesel.
