proud truck. I just finished replacing 4 of mine that broke off. It's easy to do. You will need a 21mm socket to lossen the caliper, a lug wrench, jack to lift it up, and a brass hammer. About a 1 beer job, if you stretch it out. Just break loose your lug nuts, remove the wheel and loosen the top caliper mounting bolt (21mm). Then remove the bottom bolt so you can rotate the caliper out of the way and remove the rotor. There is your access to the studs. On my '02, I had to insert the new studs from the back side of the axle because the dust/debris metal piece that protects the rotors had a small relief cut there that allowed this. Line up your broken stud with this area and gently but firmly tap with a BRASS hammer outside in to remove the stud. Next, get your replacement stud and insert from the back trying to make sure the "teeth" that are near the head engage with the ones in the hole. Gently tap the new stud partially into place, just enough so that it won't dislodge when you are bumping against it to replace the rotor and the wheel Revers all steps to re-assemble and don't forget to tighten BOTH caliper bolts! Replace wheel and tighten wheel studs. When you tighten, you will notice your new one is still short a bit. Slowly wrench down on it with your lug wrench and it will seat the new stud into place. On my '02 I neede about three threads past the rim for it to be completely seated, but you will know when it is because it will be tight. Don't forget to check your lug nuts after a day or so of trying to make sure everything seated fine and re-torque if necessary. Part number for the wheel stud on my '02 F350 was F81Z1107AC

Make sure what size yours are. Mine are 3.125" (3 and 1/8") long and all the auto parts stores had were 2.875" lengths. Had to go directly to dealer with MSRP of $8.12 each. If yours are short (2 and 7/8"), I have a few extra new ones that I can't return and would be glad to send to you. Let me know.

So far so good. I put them on for plowing only, not that I've seen snow yet. This is my second season with them and they worked great last year. They replaced a set of GY MTR's. Mileage is unknown because I switch tires depending on season. But if I had to guess 5k and they still look new.

There's some pretty-expensive bearings that you're going to be putting flat-spots on.

So the picture below shows where I'm at. 4 broke studs & 4 slightly bent studs. How in the world do I get these things out? The Ford Shop Manual I have says to "use a suitable press to remove it from the disc brake rotor" I'm assuming they mean the hub. Do I really need a press? I don't want to damage anything with a hammer but I'm a bit up a creek here.

How in the heck did you manage to do that much damage to the studs? Was the truck in a accident? Is the wheel OK? Replacing the hub units might be an easier task....
