posted earlier, but i think because i posted a link it didnt get approved: my car had the issue where the nut came loose, i tightened it up and it was fine for about a month or so, then the noise came back and the nut was still snug. took out my hub and hearing tho. as for the price of the hub, yeah, ford is the only one who sells it. on the bright side, ford racing sells one too, for about $160 + shipping from summit racing. the bearing they sell as well for about $50 or so. a few things to point out from when i did mine: 1) make sure to replace that nut that holds the half shaft onto the hub. my understanding is that its a one time use item 2) make sure you mark the camber bolts before you remove them, that will make your life a bit easier and not make you have to get an alignment afterwards 3) make sure you have a machine shop locally who is open on whatever day you decide to do this as you will need the bearing pressed off the hub and you will need the new one pressed on. unless you have a press at home, in which case that would be awesome.
