Some things to take into consideration when going with any control arm would be how easy it is to rebuild the joints and find parts for them. Click to expand...

Yes and no, sorta, maybe. There are things that logic dictates which you can apply to any product if you view things a bit objectively but that doesn't always work which I will illustrate with your next sentence.There are a lot of things to know about a rod end (generic for the thingy on the end of a control arm that lets you attach it to the axle and chassis) One of them in the case of rebuildables is how well the cartridge bits or the stuff that fits into the barrel can handle side loads like when you slip off of a rock with your tire and land with the weight of the rig pushing sideways on the arm.The Currie JJ has urethane races to provide a bearing surface for the misalignment ball and they are a very tight fit into the barrel and they get compressed very highly when you push the washer down to install the snap ring. The outer surface of the urethane gets no grease so when you load the joint sideways, the misalignment ball further expands the urethane so it grips the inner wall of the barrel and really slows down how much load is placed on the snap ring and groove. It works so well that I've seen single joints used to locate a rear axle at the end of a wishbone with the joint mounted horizontally.Now to the ease in rebuilding part and why that may not be the best criteria. Daystar was the first company to knock off the JJ. Their claim to fame was how easy it was to push in the races by hand and how you didn't even need a vise to do it. While that sounds great on the surface, they defeated one of the key features of the joint to make it easier to rebuild. They also defeated the portion that makes the JJ solid, firm, and yet still has isolation.So, to your first criteria, which one is best? The one that is easy to rebuild or the one that is a bit harder to rebuild?To add some stuff to the mix that may invoke a bit of reflection, I just removed a set of JJ's from my rig that have been on there for at least 10 years, mostly on 40" tires, mostly in JV, and they were as tight as the day I installed them and they have been through hundreds of trails in JV without ever being rebuilt. The reflection part is perspective as in they have been in use longer than some of the companies have been around that are now selling the latest and greatest.
