So lately I have noticed a vibration under my feet under the floorboard however I can only feel it when I am gradually turning right in a gradual curve with the RPMs at about 1200. I thought it was the Y pipe exhaust at low RPMs but I am not sure. Jeep is a 2015 JKU Sport with a 2.5 Teraflex lift with 35 and 373 gears. It only has 5000 miles on it. Anyone have any ideas??? I have been under the jeep and wrenched on everything. It's all tight.... Don't know what else to look at. Driveshaft is tight. Thoughts or suggestions.
