The area in question is on the bottom of the front crossmember.Over the years people have lifted the truck up by putting a floor jack underneath the center of the crossmember ,and over the years it has pushed in a little.The structure of the crossmember is still fine.Its over a space of 6-8 inch square.I doubt anything bad will come of leaving it like this ,its just anoying to look at ,because its not right.How could I pull it back out?
