If you are going to be bashing about in the woods, you can get rock sliders and weld them to the frame. JohnHarden has them. He posted pics of using them as a jack point, so they seem plenty strong. If you replace the studs, they will break again under the same conditions. I had an old FJ40 with an overhanging rear step. After replacing broken bolts about 10 x, I finally just left the step off.
