(I could leave a stop light in 5 gear in my vette and it would move, try that in the M and it will most likely just stall).
I have stated it prior and was dismissed by the rude posters of this board, that I have personally heard a few different cars have an audible knocking on tip in of the throttle when slightly lugging the car around. The first car was constant and I don't know if it is still running and the 2nd car only had the issue after presumably bad gas and the noise was never heard again. Either way, a light knocking under load is no good.

S85,
Yes, exactly! You nailed it.
I recall your post, and your post is what put this idea in my head. I thought about it since you mentioned it, and it seems, at the surface, to make sense. I'm not saying this is what causes the bearing issue, but I can see how it is likely bad for our engines to be exposed to that type of driving.
If I recall you had planned on making a post about this issue, correct?
