How would you remove this busted stub>>>>

If it were mine, I would sink a cutoff wheel flush with the floor, then reweld the square tubing back after doing the spindle repair

Best choice might be an air-arc or plasma if you have access
 
Not gonna work well on weld. Need a stone of some kind. Carbide bur may do with a lot of patience, if it gets away it will chip.

This, if you do not have an air arc or plasma, welding up 2 slots I would think would be the easiest/fastest.

Well, it’ll probably be a lot less of a PITA doing it off the truck and where it’s easy to reach. No sense welding in place if you don’t have to

Post pics when you’re done!
 
Is it just square tube? If so I’d lop the end off with the spindle and cut a new piece with a square sleeve inside of it.
That's not a bad idea.

You could weld the bottom of the spindle to the replacement chunk out of the bumper for better welding, then weld the chunk with the spindle back to the bumper. Then weld the top side to the bumper.
 
Personally I would use a hole saw to cut through the top and bottom of the bumper to remove the old spindle. I'd then cut two fresh cores out of a piece of plate steel the same thickness and weld the bottom core to the new spindle so you don't have to try and weld inside of the bumper. Then you can chamfer the bumper faces and the two cores, tack weld the two cores to the spindle and the bumper then do a root weld and a many filler welds as needed to bring it up to past flush. Then bust out the grinder and smooth it out.
 
Just cut it off as close to the top of bumper as possible and grind it smooth. Then install something OTHER than a trailer spindle and count the old remnants as stiffening. Why put it back to the way it broke before?

I did think about a re-do.. the fail was not the spindles fault. Hours of Pismo dune running + Ey-Bolt latch vibrating loose.. add a fat hill climb .. gate swing open and Snap! <<< at the pit stops made I SHOULD have been checking that Eye-bolt but I did not... so it's my fault also :-)

Thanks for al the replies :saweet:

You beat me to it, I would use the hole saw.
