Hi everyone, I currently have core 4x4 control arms with rubber bushings on one end and Johnny joints on the other. The rubber bushings have failed twice now so core 4x4 is going to replace the base of each control arm. Basically I will reuse my old Johnny joints and install them into the new bases which will have either Johnny joints or poly bushings. My question is, is it worth extra money to get Johnny joint bases instead of polyurethane? My Jeep is strictly a daily driver but I want whatever will drive the best and last the longest. Thanks
