the hub is a NON-servicable unit. You can goto carquest or napa to get a new front hub. It includes new bearings, seals, and hub. It bolts to the spindle with 4 9/16" head 12 point bolts. Take one of those bolts off and take it to a place that has fine thread bolts, and get another one that has the same threads. Take the caliper off, and the 1 11/16" axle nut, and then the 4 bolts on the back. Take your new bolt and put it in one of the holes, beat the heck out of it, move it to another hole, repeat. Do this till it falls apart. Do not use one of the origional bolts, because it is grade 10 and hard to find. And you will mess the head up on the bolt so it might be hard to remove and move to another hole. Throw it all back together the way it came apart with plenty of antiseze. This will make life easier down the road. Mu hub was $227 + tax at car quest.
