My hat is off for this TJ Build it is truely perfect in my opinion. Great job to Robert and Mr. Blaine. I have grabbed a few ideas from this build. Very well done with all the right parts. I sent Robert a PM asking a few questions. Thanks for shareing your knowledge and more pics would be great.
I wouldn't be worried about the actual joint or even a bolt (providing you used a 1/2" or larger center ball) failing. The smaller joints are just not as preloaded and the bushing halves are smaller. It certainly wouldn't happen overnight but they'd wear out....at least that's what I feel would be the case. They do fine when sharing the load but the bigger joints have been proven to hold up no matter what for a very long time.
I would agree with the longevity issue, I've already replaced 1 upper JJ and probably should rebuild another if I don't upgrade soon. My lowers are still tight as can be after 20,000 or so miles.
Going price around here for a high pinion 30 is $350-400 (if you can find one) and I got tagged $10 for the upper control arm plus environmental fee. The factory locktite was still on the stock torx bolt and the only way I could get the axle out from the Jeep was taking the upper off at the unibody. The unibearings are also rusted onto the knuckles and I didn't have enough hammer with me to knock them loose so the axle shafts added to the price too.
