On this side of the frame rail there were four cracks under that piece of 1/2 x 2 Flat bar. All the cracks were stop drilled and the cracks were gouged out and filled then we put the flat bar over the top to strengthen the bottom of that frame rail.
I'm sure someone's going to ask why I didn't skip weld the flat bar. The answer is if you skip weld that aluminum bar you create a stress riser at each end of a weld so that would be someplace for a stress crack to start by welding the hole Bar you eliminate the stress risers and you are less likely to have cracks overtime.

Yes that is true, and with the aluminum welding it presents problems of it's on. The cracks that I am repairing all started at the ends of the welds for the rest strip.
This brings up the question is the frame rail on the box too thin? Or is it just fatigue over time and the weld ends being a stress riser?
I think what I've done is going to be good for at least 5 to 10 years depending on how the truck is used, or is that abused?
