sorry

when i go to assembly the rotor hub assembly after feeding through ABS wire and trying to mount the rotor to hub it seems like the rotor wasn't cut out big enough for the hub to slide through

grabbed the pic from the how to

and when the rotor goes down it won't go back the flange where i mounts to the spindle

Fixed my other post I misunderstood your issue from reading too fast. I thought the rotor was hitting the spindle as you were installing the hub to the spindle.

Also how much does it seem to be off? You could just have a sloppy casting on the hub, if it's minimal just file it until it fits.

Looks like those rotors were casted badly without enough clearance. I would return them and buy them from someone else.

The flange on the hub is the same for all years so it has to be a manufacturer flaw from the maker of the rotor. Bring the hub in and explain when you return them so they can call and alert the manufacturer.

What brand rotors did you use so others can avoid this problem?

Not only is there a casting issue the mounting holes appear to be off center.

Are both the rotors and the hub supposed to have the bolt hole threaded, seems like that would cause a problem bolting them together.

just the rotor is threaded for the rotor to hub mounting and then the hub i threaded in the case of hub to spindle mount

and i used Centric Rotors

I have seen this issue from centric rotors before. Those two rotor castings are awful. Spend a little more money and get some better ones. Just my opinion.

I would still swap those rotors back out, the holes on them are off center on the flange and look awful. They shouldn't give you any trouble returning them.

Also if you are using z71 make sure they are 2wd the 4wd will fall apart in a couple days without the cv and axle nut preloading them.

The rotors are definitely the issue. Even if you find a hub they fit on, I suspect they will not run true and cause vibration while braking because of the way the bolt pattern is set in comparison to the stopping surface.
