I want you all to assume that this is the set up, 35inch tires auto 4 dr rubicon. Now I want to re-gear to say 5:13's and add cv joints to the front axle, new rive shaft with u joints probably 1350's and c gussets. What will be the weak link? will it be the ring and pinyon , the axle or the u joints? I am planning for breakage some time and would like to set the jeep up so the in that event. the easiest thing to fix is the one that breaks.

 

I would say your pocketbook. Lol j/k.

Actually that's a good question.
