I have searched and read and cannot find any suggestions. So any suggestions are welcome. I just replaced wheel bearings and races and put new rotors on the front of my 1999 100 series. After reinstalling the rotor/hub/wheel bearings I get a rubbig sound and it looks like it is coming from the large heavy piece of metal the brake caliper mounts to (sorry I don't know what it is called).
It is acting like the hub and rotor assembly are sitting slightly off, causing it to be closer on he top, and further away on the bottom.

I have adjusted the dust shield and nothing changed. The brake calipers are not mounted currently. When I tighten the wheel bearing adjustment nut to the specified torque the rotor is clearly rubbing. Is the caliper mounting bracket (not sure what it is called) bent? Is the thickness of the new rotors causing a problem I didn't notice before. Are my wheel bearings reinstalled wrong or did I press the inner bearing axle seal in slightly past flush and I can't see it with my eye, but it is enough to cause this problem?

The screw driver is pointing to the concerned area.

Can you take another pic showing the outer flange in relation to the caliper? Just like the lower pic but farther out towards the stud area. It's just cut off in the lower pic but something doesn't look quite right there, like the caliper isn't seated or something.
 
There should be no gap between the hub (flange) and caliper. I think I see a huge gap in the lower pic. You may need to draw it tight with lug nuts and washers to seat it fully if it is not seated.
 
Something is fishy with your bearings. I would pull everything off and recheck. The larger inner bearing should limit how far the hub/rotors sits.
 
Maybe the inner bearing seal isn't even. I read all your responses and checked all the bearing orientations and think everything is correct. But this seal isn't perfect.

I connected the caliper. Pressured the pads onto the rotor to see if it aligned it any better. Nothing. I will reinstall and see. It is almost like it isn't sitting well on the spindle or the caliper mount is bent. I can't see anything wrong with my bearings or races. Thanks all!!!

Just reinstalled hub and bearings along with caliper, new pads and the new rotor. I also installed the front wheel and still have the rotor rubbing on the upper caliper mount (which should mean play at 12 and 6) or something allowing it to go too far in at 12 o'clock (bearing seal set too far in 1/64" or something?). Is the thickness of the new rotor what is causing me to notice a previous problem not bearing related? Not sure if my tie rods or bearings or seal or spindle or what is the problem. I am tempted to bolt everything on. Drive around the block and see if it settles. Probably a bad idea and luckily we have somewhere to be so I have to stop till tomorrow. Hanks for any tips. I will remove the "real time" from the title.
Thanks for any more tips.
 
It seems to me the most likely cause would be that the new rotor is not fully seated on the hub. This is assuming the hub splines slide freely onto the spline of the axle (which means the inner part is not the problem, and likely not the bearings or seal).

I would recheck the rotor/hub and insure the 5 bolts draw the two pieces up tight to each other.
 
I just did rotors and pads today, something isn't right if you're rubbing. Like others mentioned, make sure that rotor is fully seated to the hub.

It looks like there is a gap between the rotor and the hub in the second pic. They should be flush, no gap. I'd pull it, set it flat with the rotor down and work your way around with a mallet or dead blow hammer until it's nice and snug.
 
I will try the hub and rotor spacing tomorrow. When I spin the rotor it doesn't wobble. The top of the rotor is too close, and the bottom is far away and it stays consistent when I spin. Earlier I checked the rotor to hub clearance and couldn't find any space. Before putting them together I checked for metal burrs or anything that would keep them from bolting together. Maybe I missed something. I made sure I tightened the bolts down evenly drawing the hub/rotor together but maybe I need to try again.

I will mess with the hub/rotor more tomorrow. I hope I don't have to remove the seal, bearings and races and redo those.
 
If the inner bearing race was not fully seated there would be more clearance between the rotor and knuckle, not less. I don't think you have to worry about redoing the bearings and seal. Either wrong rotor or not seated properly. Have you verified the rotor part number to confirm it is the correct one?
 
Swap rotor sides and see if you have the same issue. Also, there is a brass bushing on the back of spindle. What's the condition of it?
 
If you have all the old parts verify that the new parts are the same. You may have received the wrong rotor or bearings.

Since the OP reports no wobble, my next best guess would be the wrong bearings or race - can a correct race be driven in such that this could be the result?
 
Thanks again for the help. I think my spindle may be worn in places and causing the problems...
Ok, I think I have all the right parts after double checking my numbers. The passenger side went really smooth. The drivers side is where I am having one issue, the hub/rotor seems to be sitting to far inward and rubbing. I separated the hub/rotor, made sure there was no debri or metal burrs keeping them from mating. I reassembled and the same thing is going on, rotor rubbing on upper Brake caliper mount. . I removed the wheel bearings, hub and rotor. I cleaned the spindle off and was inspecting the spindle. It looks to have wear spots on it. My old bearing seem to need a packing sooner than later. But I can't imagine the spindle would be damaged enough to not allow my new hub/bearings to sit properly. Any place I can find new spindles besides Toyota? I can contact the mud dealers also. I have heard the axle spindles are connected to the steering knuckle which is going to cost me if this is the problem.

Any way my inner bearing seal, or bearings could be causing it still?

Pics of my spindle coming soon.
 
Here is an up close pic of the spindle. The old bearings didn't look bad just didn't look like they had good grease in them (kind of thin and not very much left compared to the passenger side).

Trying to be logical, if the spindle was worn, I'd think rubbing would have occurred prior to the work you did this weekend. If the spindle is ok and you confirmed that the hub and rotor are fully seated, that leaves the rotor, and the bearing/race combo. Also, your seal looks properly seated.

Things I would confirm, is it the right rotor, is it the correct bearing/race combo, is the race installed correctly? Sounds like you're doing all those things, I'm sure you're going to get it figured out.

edit.. just saw you posted a picture of the spindle, I don't think it's causing your problem.
 
I don't think the race can be pressed in too far. And if I didn't press it in enough, it should be keeping the rotor even further away from my caliper mount like others mentioned.

Not sure though. I used a shop press, an old race with a slit cut in it and a block of wood. It seemed to go in smooth and it is the same part numbers as the passenger side. But I might have to pull the seal and bearing and check it again. Here is some more pictures of the wear on the spindle. Nobody has a seal in town I can buy, so I would have to order. This is taking way too long for my patience.
