Warning: my drawing is crap but it probably an accurate depiction for why all the threads are busted.
I have an aluminum undertray for the ralliart. It bolts up between a chassis brace and the frame. Unfortunately, all 3 bolts that hold the brace/tray seem to have stripped their threads. They all turn wonderfully freely and never release. This is blocking me from servicing the transmission and transfer case. Anyone have any sweet tips on getting these things unstuck using my driveway and charisma? Happy to drive to harbor freight and pick up an extra tool or two if it will help.
I’d like to avoid drilling them out if possible because it’s a really awkward position under the car.

Sell it & buy a Juke.

If they’re free spinning, the drill might not even work. From what I’ve seen of things like this, there’s usually a nut tack-welded inside, so if free spinning I’d think those welds broke. When I ran into this with the rear sway-bar on my car, I had to cut into the frame rails and weld a new nut down. :(

JB weld a nut on the other side...or to the front if you can’t get to the back.....or get a helicoil kit.

I’m guessing there’s a tack welded nut, or a cage-nut that the screw goes into that’s spinning. You may be able to get something between the undertray and the body to pry down, putting a force on the screw to hopefully pin the nut in place and allow the screw to unthread itself. (I do this alot with screws that thread into plastic grommets, the plastic will strip and the screw will spin in place).
Or just take a grinder and grind the head off of the fastener, and replace.

This post was just waiting for that reply.

These were the two options I was thinking too. Get a screwdriver or pry bar to pull down on the bolt while unscrewing. If there isn’t room to get something under, you could get a vice grips on the head to pull down while turning it.
When all else fails, just cut that shit out.

Clip tools work really well, too. They’ll fork around the bolt/screw, and focus or isolate the pressure.
PS: You know it’s a slow day at work when you’re taking photos of clip tools.

I am guessing stripped is the wrong word sounds more like the tacks have broken off allowing the nut to spin freely. If so you can pry down on the head of the bolt and use an impact or what not to try and get the nut to jam against the remnants of the weld/friction to get it to spin out.
Alternatively just cut the heads off the bolt and push the remnants up into the under tray. Then replace the stuff after with a longer/better bead.
