Rubicon Express rear adjustable upper control arms.

will putting flex/jj upper control arms while having regular lowers give you any more flex? or do you need to do the bottoms also to gain any flex?

having just went the weld-nut route last week for that problem (luckily only one) i cant help but ask how its holding up?

I wanted to pass on my experience with the RE Superflex Joints. Be very generous with the Never Seize on the thru bolts. If you need to remove them, they are famous for freezing up. I have removed 4 of the joints after breaking a bolt on the rear uppers on two seperate occasions. The bolts that I sheared were 10mm grade 8. I had to cut them on both sides of the misallignment tabs to remove the arm, then buy a new steel ball due to the fact that the bolt was frozen inside. When I say frozen....I mean putting them in my 50 lb vise and hitting them with a 5 lb sledge about 150 times with no luck. I talked to RE and they said it is common in the northeast due to road salt and weather conditions. My jeep is garage kept and i dont drive it in the winter. I solved this problem by doing two things. First, I drill out the hole on the metal ball so it will accept a 7/16 bolt, which is slightly larger than the 10mm, remember your going to have to drill out your brackets also....which is very challenging with the rear uppers, especially on the skid plate side. I use a diamond barrel bit in my angle air grinder. I use grade 8 hardware and coat the bolts with never seize. I have never had to remove the ones that i have repaired, but with the larger bolts...hopefully I wont have to.
