This is an excellant website but when it comes to rotor removal its not. It stops at 1985 so I have a 91 and it does not explain how the aluminum hub housing comes off. I know there are 6 studs with acorn nots on them OK now the nuts are off so whats next. There is good detail as to how to seperated the rotor and install a new one but it dont tell how to get the assembly off the truck.I know there must be something inside there that that aluminum housing is preventing me from accesing.
