I have a 2012 Pro 4x4 and getting ready to refresh the front end and upgrade to 5100's on mid perch. I want to replace my ball joints, tie rods (outer and inner) sway bar links and control arm bushings. Rock Auto has new AC Delco control arms with bushings and ball joints for near the same price as buying the bushings and ball joint ( especially if you think of time and labor). Would it be better to just replace the control arm assemblies. Are the rock auto ones worth it or should I go with some other brand?
