Question about 1989 Ford F 250
Remove the wheel, remove the brake caliper, then remove the rotor. I believe on your vehicle you have to remove the dust cap in the center of the rotor, then remove the cotter pin, then remove the hub nut. When you put it all back together you will want to change the grease seal at the back and clean and re-pack your bearings. Make sure you look at your bearing races closely for uneven wear patterns. If you are replacing your rotors they will come with new bearing races installed, this is an opportune time to replace the wheel bearings with new ones. and again, make sure you install new grease seals and pack the new bearings with grease. When tightening up your hub nut make sure you get it tight to where you can feel a bit of drag when spinning the rotor, then back off your nut about 1/4 of a turn. This is vital that there is a bit of play as when you start driving the friction of the bearings going around and around will still generate heat and expand the metal of the bearing, even with all of that grease. If the bearings are tightened all of the way up they will seize and fail very quickly.
