Don’t have one in front of me to compare to, but right off the top I’d say you’re correct and it’s bent.
I don’t remember there being that much of an angularity difference between upper and lower.
It doesn’t really have to be precise in some cases, because the ball and socket of the ball joints can compensate for a little out of whackness. But yours looks pretty far out of whack!
Yes, cast can bend. It can also break if taken too far or under the wrong conditions.
But I’ve seen it bend. At least I thought they were castings?
Could they be forgings? Don’t think so, but I don’t know either. I’ve always just “assumed“ and you know what that can do.
