imagine if the driveshaft was at a 45 degree angle to the outdrive and the the dogbone and outdrive was glued up so it didn't pivot (super-extreme case of binding) when you apply the power if they are sweeping forwards they will 'push' down on the hub end (wheel)
if they are sweeping backwards they will 'push' up on the hub/wheel end.
we dont have 'that' much resistance in the outdrive/bone end but the effect is there. on some cars more than others depending on how efficient their outdrive/bone end materials move on each other
its not the easiest thing to explain, but I hope it makes sense
