It's been brought up in a recent thread that dynometer tests, upon which a 4WD/AWD vehicle is driven onto 4 rollers to have its emissions checked, are bad for an SVX's AWD system. Unfortunately and very surprisingly, the thread contained no evidence of how this is so. Since I didn't seem to have any luck asking about this in that very same thread, I was wondering if somebody would be so kind as to explain the reasoning behind this claim. Thanks so much.
