I have a 2016 Ford Transit Connect XLT SWB with only 39,914 miles on it. Today I was driving and I felt a "knocking" through the firewall directly behind the floorboard under the dash. I instinctively turned off all noise makers in the cabin (blower motor, music) so I could listen to see if I hear anything with the "knocking" I was feeling at times through the firewall. When turning to the right, there was a intermittent clunking noise as I'm turning. I pull into a parking lot, put my van in park and gradually turn the steering wheel and again, I hear and feel a clunk then turning my steering wheel. Sometimes it's minute..I hear a clunk but don't feel it and other times I hear and feel it. Yes, I have some general car knowledge on noises a car and make and what could be creating the noise. So in the empty lot, I put my car back in gear and drive around a bit cranking my steering wheel left and right to see if I could isolate the noise. I couldn't. It didn't have a "click click click" of a cv joint, but I probably has to be something mounted against the firewall of my van, directly behind the drivers side for me to hear AND feel the clunking noise. My van is low miles for its age so I never thought a component would fail this early. Can anyone help me isolate what is making the noise that I could even FEEL the knocking?
