I agree, I'm not trying to scare you, but it could turn into a safety issue if something locks up while your driving. Good luck.stop at a dealer and have them check it out..if its getting worse you may not like the end results if you let it continue.
no offense but you don't have it in 4wh and not realize it?
You'll get a good price selling it right now.I love the power torque and gas mileage but if I have to deal with a vibration on a brand new ecodiesel I might just sell it and move on.
