It does look like its flexing to me right around the area thats bent to clear the dif.

But it seems like if it flexed under conditions as light as those, it would be almost undriveable on the freeway.

Just curious, what width tires are you running? The wider the tires, the more stress will be applied to it.

EDIT: I see you are running 315's on 8" wheels. So that should not be that big of a deal.

 

Actually, right now I'm on the stock tires (255/75R17). I'm gonna try airing them down tomorrow to see if it's more noticable.
