How heavy is that levee?
Whats your 60 ft?

Never ever heard of such breaks.
Surprise that motors have not fallen out of cars with those ugly bad welded K-frames also.
Notice how pit-bullish my modified steel member is compared to the factory papier mache' type posted earlier.
The aluminum will be just as bullish because it work stresses itself. That is why I keep a keen eye on my front strut bars.
I think that a bright White is an appropriate color to apply on stressed members like that so that cracks/bends/distortions could be easily discovered by the naked eye during inspection. Black, especially gloss black covers too well, thus creating a bad situation.

Maybe you should try a whole new one and throw that one in the melting pot. The factory gussets are a complete laughing stock.
