Fits an early '99 Ford F250 SuperDuty. Be sure and purchase the installation tool. Yes, the tool is expensive but if you try the homemade hack with the pipe flange that people are showing on Youtube, you will never get this part installed correctly and will most likely damage it. This part is the outer seal. There is a secondary inner seal that goes between the yoke and the outside edge of the axle you will need to replace also. The part number for the inner seal, or dust seal as some people call it is 710493. The installation tool has a secondary purpose in that it seats the axle to the correct depth when installing the axle back into the truck. If you are purchasing this part, it is because the original failed. Unfortunately, this is no better than the original part and will likely need to be replaced in few years again. I could not find anything better than the factory replacement. If you are tearing your truck down this far, you might as well replace all the crappy original Ford parts. Buy some new Moog ball joints and axle u-joints that have grease fittings. (The factory parts had no grease fittings and that is why they fail.)

Perfect fit at half the cost of the dealership. Must use special driver to install, don't try drifting this on.
