I have had this issue since day one of my rcx install on my 2012 ram 1500, after fighting with RCX for weeks , I sent pics , described the issue and still no help from them , I had to take and send a video to them of the shutter to make them believe me, strapped a go-pro to my frame rails this is more common then people think . Its just that most people would no notice this unless you know your truck . They finally built me a set of rear upper adjustable control arms and sent them out . I had them installed and readjusted 4 times , my issue is about %80 gone but I still feel a small shutter on acceleration .. Talk to mitch at RCX he knows all about this issue , don't let them off with this ! .

They told me to snap some pics of the pinion angle and send them in.
Does this happen alot? I couldn't find any posts about this anywhere. You are the first person to tell me I'm not crazy
