I know on these trucks the front wheel bearings are a single sealed unit with the hub. The problem is that i don't know what ones to get, and i need them ordered ASAP so i can get my truck off the jack stands in the middle of the driveway. I'm going to go with timkens, since they are a better brand. I can get them for 175-200. The problem i have is that the website i am ordering them from has different ones listed, one says for fine thread studs, and one says coarse thread studs. I don't know which i have. I'm assuming it is the 4 studs that hold it to the axle right? Or is it the lug studs? If it is the 4 mounting studs i have a pic of them, maybe one of you can tell me if they are coarse or fine. I don't anything to compare it too.
