Johnny Joints... Great.... they will wear quickly with off-road dirt and grime. Then you'll have another reason for DW. They are great for articulation, but terrible for anything that sees miles on the street. Drop Brackets and support braces from RE will solve the DW for you... Trust me... I spent a year chasing this back in 2000 before anybody was really lifting the XJ's with more than 4"es of lift... well not many XJ's were lifted at all 10 years ago. I found a Jeep Mechanic (now a good friend of mine) that saved me from dumping the Jeep. He told me the CA short arms were at too steep of an angle. Way out of Jeep spec. He had me get the caster down (which Tereflex also told me to get to -2 degrees to solve the problem, as they were working to fix the DW as well at the time), and he told me that RE was making DB's for the UCA's, and LCA's. When they came out, I ordered them, had them shipped out the overnight, and put them on that weekend. Ride was fantastic, and never had DW again. Get DB's for the short arms, or get LA's...
