When I put the control arms back together, one of the most important things is to make sure that the jam nuts on the flex joints are torqued down VERY well. Rock Krawler specifies 300 ft.lbs. of torque. This is needed in order to keep the jam not from backing off. Once it does the threads will start to wear and eventually the joint will just pop out of the control arm.
I built this jog from some 1/4″ steel. It’ll keep the one end clamped to the workbench. The other end is slipped into another jig into a vice, keep then flex joint properly oriented. I’ll then be able to get the wrench on the jam nut and crank on it. Should do the trick.
