Had this issue for a year and a half now on my 2018 JLUR. When I lower the tire pressure below 35psi, the thrum thrum thrum noise is better, less noticeable. Been following this topic since day 1, does not seem that anyone had found a solution yet. So maybe this tip helps to make your life just...

I have the exact symptom on my 2018 JLUR, it only happens around 61 to 67 mph. "Thrum.. thrum.. thrum" is really the best description of this vibration. It happens every single time when you are in this speed range. Feel like more noticable if your 8-speed tran is in the 8th gear and just...
