The years have finally taken a toll on my truck's frame, producing a 3" long crack behind the driver's radius arm drop bracket.



What's the proper way to fix this? From what I've understood I need to drill a hole at the end of the crack to relieve the stress there and keep the crack from continuing. Also I need to grind a groove along the crack to give the weld something to flow into. But should I do this on both sides or just the outside? The crack is very close to the body mount rivets so I dont think I could plate the inside of the frame, but I do think I can box the frame to help strengthen the frame in the in the drop bracket area. Any other ideas?
