    I'm comfortable with welding...i did plenty of it when I had a job

    I'm just now learning the techniques involved in heat treating and stress relieving so I'm not yet that familiar with them. I figure as long as I do some stress relief and reinforce the frame it should be fine. Nothing is going to 100% keep this problem from coming back. It's a 21 year old frame and there is a lot of stress applied to the frame from that radius arm drop bracket. As long as the truck stays in one piece another couple years I'll be happy.

    Sorry, I just got out of a fluid dynamics midterm and my brain is fryed.

    I must have used

    frame age=(Pa/gamma)+Za+(Va^2/2g)=21

    It's 11 years old

    if you want to shot peen after your done you can get an air hammer attachement like I have that will do it to it a million times by just pullling the trigger on the air hammer. pre-heat is the most important like everyone said. shot peening would be a good idea to relieve stress iwhere the weld meets the parent material...what is that, the fillet?

    Luis, Jose, and I fixed it this afternoon. Once removing the radius arm drop bracket and cleaning away some of the rust, we found the crack was actually two cracks which joined, seperated, and then made a circle joining again (see pic). I used a die grinder to cut a nice groove along the bottom side, and then the portion that was behind the body mount I used a drill with a 3/16" bit. First I drilled a through hole at the end of the crack, then drilled multiple holes about half deep along the rest of the crack where I couldn't grind a groove. We then heated the area, about 3/4" on each side of the crack and I welded it up. Before it had a chance to cool I heated the area again till it was lightly glowing and let it cool. I didn't have time to box the frame, but I think it should hold for now, I don't beat on my truck like I used to.
