Does anyone know where I can find any service info on the front knuckle assembly. I was doing a front brake job on my truck (02 F250sd 4x4) and when I was trying to remove the rotor I was turning the wheel hub and heard some grinding.So I removed the front hub from the knuckle and spun it it was smooth.Looking into the knuckle I found what I think was the problem.The big seal in there was all tore up and completely wasted. I am just wanting to know how it all goes back together so it is done right the first time. I did some searching and only found that it takes a special tool to reinstall the seal. I am just looking for like an exploded view or sevice manuel for this Thanks Mike.
