Big Orn - I didn't see in your posts which rotors you used. Were they the pre or post 3/99 rotors? I am assuming you used the pre-3/99 rotors with the post 3/99 hubs and that was why you were questioning this?

That is good to know. I have a brake job coming up and I am researching parts now. Makes me wonder if I should get the pre or post 3/99 rotors. Still have my orginial hubs (build date 7/98). I suppose I should go ahead and get the ones that match my hubs now and if the hubs need to be replaced I can use your information. Thanks so much for sharing and being FTE's experimental rig on this!!

After 4500 miles there is nothing to report...which is good news.
I will say again: If you decide to use the post 3/99 bearing assy, please assure that the caliper will have ample room to work freely. Not all tolerances for mating surfaces will be the same.
Just FYI

Update:
I have almost 10K on this bearing with no troubles to report. As a matter of fact the tire that ran on that bearing had much less scalloping, almost none at all.
I will definitely replace the other bearing with the same setup.

I think I found the difference to be 1/8 in on the backspacing of the rotor from pre 99 to later .My problems started when I tried to fit new rotors on my 99 truck built in 98 ,the rotor sets to close to the caliper grinding my rotor into the bracket . I still need some rotors that fit with an 3.375 backspacing rather than 3.5 that it the problem .
I have been through 3 sets of rotors from summit and still cant find one that fits .it almost seems easier to upgrade to newer hubs but I just want some new rotors.

I have to replace my hub assembly on a ealy 99 F250 and want to make sure I am getting the right parts. So I can get a later hub assembly and use a rotor for that year too and all will be fine? Here are the parts I am looking at.
