Wheel Bearing Replacement

so halfway thru pennsylvania my right front wheel bearing decided to die. i tried to replace it in a parking lot in Penn, but i discovered that the inner bearing race had spun, and i now need a new hub. my dad trailered it the rest of the way, so now i have a sad broken jeep in the cage.
sooooo my question is, where can i get a cheap hub?
advance has one for 120, is that the best i can do?
also, the hub and rotor are 2 seperate assemblies, but mine looks like it is just one big cast piece (probably due to rust, i cant see the seam). anyone know if i will be able to press the rotor onto the hub with a simple hammer?
86 CJ-7 D30 front
im also wondering if anyone has a torque wrench, and a hub nut socket (im not sure of the exact size) that i might be able to borrow. ?

The hub and rotor are held together by the wheel studs. A hammer and punch is all thats needed to install them. I have a hub socket you can use. PM me.

do you guys think that this would be a good tech demonstration for the next meeting? i know leech said he wanted some suggestions...
and im gonna be doing it in a parking lot anyways lol.
also, i would like to use a jack stand if anyone has one they could spare for an afternoon, my hi-lift makes me nervous.

did either of the bearing races spin or sieze on the spindle?
recent experience shows us that breaking down parts that have rusted together for 30 years is not a good idea for meeting tech.

I got a floorjack, jackstands, and air tools if you need 'em

i dont think it spun on the spindle. although i did have to use a dremel to cut off the inner race so its possible. it is a little beat up, but the new bearing seems to fit perfectly.
at the same time, i really want to do this right this time (this will be the 3rd time i have replaced these bearings... so i must be doing something wrong.)
anyone have a spindle they could part with at a reasonable price? :)
and btw, i am well aware of the dangers of a hi-lift. i've had to explain them to my dad a few times even. :)

How tight are you torqueing the wheel bearing nut? Should only be hand tight or slightly tighter. The second nut is the one that gets torqued to hell.

what little expirence i have with a high lift tells me that the safest thing to do with one is recycle it, and even then you stand the chance for a broken finger or toe.....

I have some jack stands. We can do it at the next meeting but thats two weeks away if you can wait that long.

that would be great. i might be able to wait that long.
my repair book says to torque the inner locknut to 50 ft-lbs, then back it off 1/6th of a turn. then torque the outer locknut to 50 ft-lbs.

I would say the bearings are too tight. You need to tighten them down really tight to seat the bearings(tighten, spin the wheel 3 or 4 revolutions), but then you back it off and tighten it by hand until the wheel doesn't "wiggle"(grab the tire at 12 and 6 and try to wiggle it in and out. Tighten until it doesn't wiggle anymore) It's very much a feel thing, but I've done mine this way many times w/ no problems and it is the way most seasoned mechanics do it.
