I'd say it depends on what he calls the rear frame rail. I've discovered that the part of the frame rail where it'* welded to the underside of the unibody is not strong. I've seen many bent "frames" where people have tried jacking it up. I'm not sure how strong the rear "frame" is where it is welded to the underside of the unibody. I'm just not going to take that chance.

That said, I don't like using the pinch seam either, which is supposed to be the jacking point for changing tires. I had a pinch seam crumple on me once.

I prefer to use the control arm or crossmember.
