I have ran my 5.29's for over 2 years now. no problesm at all. broken 1 detriot, 1 lockrite, one birf, and one inner axle. no nicks or chips out of them at all. When i replaced the detriot with a welded carrier i even set-up the ring gear in a couple seconds. I am not a ring anf pinion installer so i half assed it. It felt like the backlash was good and the pattern look ok. It hasn't faliled me yet and it has been run hard for about a year. I guess it has to do with what factors you facing at the time of breakage. I pulled mine out last week and it is still set the same as when i half assed it. Maybe i am just lucky. And i have no idea what brand of gears i have. i bought both sets used already in the thirdmembers.
