Crack repair requires good knowledge of exactly how the stresses are causing the cracks, welding process, and reinforcement needed to strengthen the cracked member/joint. Yes, if not properly addressed, the crack will return, usually along side the weld. One must consider the direction of the principle stress, stress risers, joint prep for welding, heat affected zone, and fatigue stress, to name a few. I think in our case, it can be done, with a really good TIG weld operator, and proper reinforcement of the tube. I know if it happens to mine, with the nearest dealer 450 miles away, I will be dusting off my engineering texts, and practicing my TIG skills. Keeping the suspension pickup points in the correct location during welding could be tricky as well. Yikes!
