Yes I can tell the weld is broken...and yes...I looked at that C_AP stuff and it looks thin and weak just sitting there...nothing like the RMS arms. I see the weld broke but like the other comments made, that short arm would probably stay straight and if it got hit on the shear plane then the weld would have broke on impact.....bad weld or bad mistake.....who's to say now.....I just have a hard time believing that a break like that occurs just driving down the street. Look at the whole damaged area around the wheel.....there is a lot more going on there that the pictures arent showing.
Mop.
