I just had my 2014 Jeep Cherokee Trailhawk installed with MFC+ 3" lift, Fox shocks, Dobinson springs and RCV axles. There is a ratcheting, graveling sound that increases and slows with speed. I have a video of it I will try to find a way to post it. Sounds horrible. I can feel a little pulsing in the gas pedal and slightly in the steering wheel. Any one else experience this and what did you do to fix?
