Corbin's CTM 44s held up well for two years... that seems like a reasonable duty cycle, IMHO. There truly is a huge amount of force converged upon the single joint in a 3-link... tough to brace for force from every direction, too. Three links just seem to work best on lighter rigs.

I'm clowning a bit on the auto-locker failure... I get weary of folks slamming ARBs, which occasionally fail to work, and generally only need seals or air lines fixed (excepting the Dana 35C, which is an entirely separate discussion), when more often, these days, I see Detroits failing big, and messily. Both are great lockers, and both work well for the majority of the cases, but I guess I prefer the small, repairable failure mode of an ARB to the larger, more collateral-damaging failure moe of an auto-locker.

Sounds like the Amigo and Dodge faired fairly normally with respect to breakage in that peer group. I hope they report it as such. Even with all the wrenching and driving, that week still sounds better than a week at work. <img src="/forums/images/graemlins/kewl.gif" alt="" />
