I needed to jack up the back end of my wife's Odyssey on a bright sunny day so the center jack point was very hard to see. Stupid me kept jacking up wondering why it was raising up high... then I noticed I was jacking up the underside body of the van. I completely missed the jack point! No real incident but now I have this huge bulge in the trunk where the stow-away seats fold into. They don't stow-away any more. Unfortunately this bulge was on the area trunk where the horizontal meets the vertical. I tried to step on it and that **** ain't flexing on account of my 180 lb sorry ***.

Hydraulic jack, 2 ton minivan.... it's obvious how the body bent. But now how do I recreate as much force from the top end to pop it back down into place?
Only idea I have is a sledgehammer and wooden 4x4
