Do the threaded rod ends come loose?
I’ve been running one version or another of this setup for over a year and have yet to have any rod end work loose. If the jam nuts are properly tightened against the rod ends they should not work loose. I’ve been running my linkage on a diesel engine vehicle (with worn out motor mounts no less – so I know vibration:) and not one problem. If you want to be extra secure, once you have the linkage adjusted to the proper length for your vehicle, you could use a thread locking compound on the jam nuts, just back them off, apply a drop of thread lock and tighten them up again. Or for the ultimate in staying power, you could try tack welding the nut and rod end to the threaded rod. The rod ends also feature a spring steel safety clip that mechanically retains the rod end on top of the ball stud.
