Speaking as an engineer only:
It's about physics. When is the entire system (the whole jeep) under the most stress? Not always but typically it's when going up a slope. Steep, only slight, rocky, smooth, slick, whatever. Where is most of the weight and most of the traction? On the rear axle. In theory a great deal more weight/stress is on the rear axle. 200%, 300% or maybe even more. So it would appear a broken rear axle to be weak when in fact it was likely about the same strength as the front.
From my limited wheeling experience. I've only seen 2 broken axles and they were both front D30s. While at the same time I wheeled the same trails with my rear D35 as my buddies' broken front axles.
So in conclusion it's just my option that a D35 is not weak/bad but just small for the job.

I didn't say it was bad, but for the money and more options the 8.25 is a better choice, and more options than that would be a 8.8 or cutting down a 9". I hate engineers BTW bwahahahahaha

I know what you mean about engineers, they think WAY too much for their own good and go off the deep end pretty often.
