I have a 2019 JLUR 2.0l with 23,000 miles. It is stock except for 2.5 Clayton lift, 37” KM3 tires, 1.75” wheel spacers, Fox 2.0 IFP shocks and stabilizer, front bumper and winch and Cav Fab tire carrier/license plate relocation bracket.
I have been experiencing a weird vibration or resonance at low speed that can be felt and heard as a drone as the vibrations transfer through the hardtop. It happens between approximately 2 mph and 15 mph whether coasting, accelerating or decelerating. No vibration while stopped or from 15-90 mph. I cannot figure out where the vibration is. I didn’t feel it when accelerating/decelerating either with the rear lifted off the ground using jack stands
I don’t think it is the engine and it happens/doesn’t change when the transmission has been shifted to neutral. Shift to 4WH doesn’t seem to make a change. I’ve re-torqued the wheel spacers and wheels. The rear driveshaft appears tight without damage or wear signs.
Has anyone experienced this? Any thoughts or tips.
