I'm in the process of fabbing some adjustable upper and lower control arms using Johnny Joints. Question, does it matter whether the Johnny Joints are mounted on the axle side or the frame side? And should the upper and lower arm's joints be on the same side, i.e. both on the axle side or both on the frame side? I'm thinking it would be better to have all the flex joints on the axle side, but if one look at the RE adjustable SF arms as an example the SF joint on the lower arm mounts on the axle side whereas the SF joint on the upper arm is on the frame side. This might be because they don't have a flex joint solution on the axle end like Johnny Joints have.
As it is at the moment I have three options wrt my upper control arms. The first is to modify the upper control arm mounting on the axle to work in a similar fashion to the lower control arm mounting (I'm fabbing a new front axle so I have to make new mountings in any case) and thus just mount a normal Johnny Joint on the axle end like one would with the lower control arm. Second is to keep the axle end standard and fab the upper control arm with the Johnny Joint on the frame side (like the RE arms) and the third would the to cut off the threaded bolt on the Johnny Joint (I have the ones with the dom tubing with the threaded bolt welded to it) and replace the bushing on the axle end with the Johnny Joint. This will allow the flex joint on the axle end, but with OE mounting of the upper control arms.
Any suggestions?
