While backing my GPW and trailer into the garage, the trailer lunette got bound in the pintle. The resulting force bent the pintle to frame brace so that the pintle is no longer square. How can I straighten the brace without having to disassemble the vehicle?

Re: How Can I Straighten a Bent Pintle Brace
You would need to heat the metal and bend it when red-hot. Then attempt to re-weld the broken welds in the photos. Unless there is a very good reason to do this, why not fabricate some shims for each of the two holes in the plate to get the pintle to stand off at a 90 degree angle like it was and forget about rebuilding the K brace on the jeep?
Since this real repair might entail removing the tub, the short cut may be more appealing and since the structural integrity of the K brace and the plate do not seem compromised, you should now sweat towing your trailer with just shims installed and the broken welds re-welded.

Re: How Can I Straighten a Bent Pintle Brace
I would pull it back into shape by applying force in reverse of what caused the damage. Since you probably don't want to use the pintle hitch to pry with for fear of breaking it, you might fabricate a simple 1/4" steel plate to pull with. As mentioned if you have access to an oxy torch that would be the best way to get the metal to yield while pulling back into shape. Then weld the broken welds back up and your good to go.

Re: How Can I Straighten a Bent Pintle Brace
I was just thinking what I would do so this may not be the best thing but I would be temped to remove the front and back plates and get some nice straight replacements. This would basically make the thickness to straighten go from 8mm to 2.5mm approx. Then I think would try pulling the remaining part out to straighten it. As the steel is only about 2.5mm thick it should move quite easily and even easier with heat. You could maybe fabricate a bracket to bolt into the holes on the bent side, chain it to a bollard and in 4 wheel drive, gently move forward. Then refit/weld the new front and back plates to tidy up.
I've never tried this but it maybe worth a try if all else fails. I've always liked a bit of trial and error.

I would just hammer it back out. Sometimes in situations like something like a brass or steel rod to hammer against enables you to hit it in just the right spots, especially corners.

I would grid off the welds and remove the plates and if they cant be straightened then replace them. Your best chance if straightening the frame underneath is to first remove those plates. One layer of metal will be easier to pound out, rather than 3 (exterior, frame, and internal support piece. The support plate inside the frame that's welded in the center which may be hard to remove.
