Ok got my 14bolt ff with 4.56s and a detroit, Turns out the brakes were trashed and looks like a spindle is messed up, Can I just speedysleeve this as a temp/permanent fix?

so what needs to be done here 14bolt ff

Mine look like that and I'm on the hunt for a better housing w/ newer looking spindles. I'm not happy with it, but it works just leaks like crazy.
There is a speedi sleeve for the seal area but not for the bearing surface. I can give you the part number for the speedi sleeve for the seal as i have a set in my garage right now that i need to install on my axle since my seals are leaking. It's a 99282 and thats a Car Quest number but i think other manufacturers use the same number.
wow say good by to that spindle.

Probably, but I'll follow that up with the question; is this a trail only rig or a street rig?
You can speedy sleeve a seal surface but both of the wheel bearing surfaces on that spindle are seriously messed up, unfortunately 14 bolt spindles are welded on and are not easily replaced (finding a new spindle and a jig/welder to remove and replace them will cost way more than a new 14 bolt in most cases).
I would find a new 14 bolt and swap your gears/locker into them (which will require setting up the gears again but lucky that 14 bolts are the easiest diff to setup, you can always post up here for help).

Couldn't you just clean up the bearing surfaces and see if some new bearing cones will press over it ok? As long as they are fairly snug shouldn't it be ok?
By "clean it up" you mean hit with a grinder? A lathe?
Either way you're going to have significant gaps on the surface that the bearings ride on. Less surface area means more pressure in the remaining areas, not to mention stress risers at the sharp edges of the remaining areas.
Would I run those spindles on a trailered rig? without question
On a rig that sees any kind of highway time? I would be looking for a new rear end.
Rear 14 bolts aren't worth much because they're so common, no sense in risking anyone's life over a rear end that's only worth $1-200.
As easy as a 14FF is to find and aquire, I would just replace it. To bad my last machine shop that did metal Plasma spray was not into rebuilding axles. That would be an easy fix with metal spray. We would just chuck the housing between centers in a big lathe, turn it down undersize, tape off the rest of the diameter not requireing coating, grit blast the spindle bearing lands, Plasma spray it over size with what ever type of material, then either chuck it back in the lathe and turn in back to stock or put in a big grinder between centers and grind it back to stock if it was a coating too hard to turn. Easy repair with that process. WAY to expensive though. It would cost more then what you could find another 14FF for. I had my D60 spindles done with that process. The material in SUPER hard, will NEVER wear out again.

I meant steel wool to remove any high spots. Don't the roller bearings them selves ride on a steel cone that slides over the spindle? It's not like a semifloat where the rollers actually ride on the axle surface. Am I just missing something?

Thats what i was kind of thinking as well.
I am by no means wanting to endanger myself or anyone else out on the road if this is not safe, new territory here for me and need solid advice.
We are gonna be going wheeling memorial weekend and funds are now running pretty low, Just bought this axle, disc brake conversion, trac-loc for the front, and a transmission. The cheapest I have found a rear axle for replacement is $150, so i dont think im gonna be able to get the wife to jump onboard with more money into this trip.
It is about 100 miles each way, plus the wheeling and running around, so i would say 300 miles tops, I was really wanting the detroit in there, but will weld up my dana 60 rear if i should hold off.
Well, they do. This spindle would need a lot more than steel wool.
Regardless, less contact surface area (i.e. a damaged spindle) will mean less friction holding the inner race down. Also, the edges at each end of the gouges in the spindle are big stress risers, begging for cracks.
I wouldn't trust it at highway speed but for a trail only rig I'm sure it would work fine.
