An axle is only as strong as the application. Any idiot with a heavy right foot can break any axle. Google 'broken Dana 60' and you will get quite a few results. While a bigger axle works great for internet d*** measuring, there are vehicles of all sorts with "undesirable" axles doing just fine. My old rig was a V8 ZJ with a rear Dana 35C which is by no means a strong axle but with smart driving and knowing the vehicle and its limits it never gave me any trouble.
