So. I had the dealership install a 2” MOPAR lift on my Rubicon. My wheels and tires hadn’t come in yet so i drove on the factory 33’s for awhile. I don’t remember noticing a vibration.
Op
Fast forward to my 37x20r20 BFG km3’s. Vibration starts. Notice it at highway speeds. Comes through the chassis, seat.
A day of road force balancing yields a bad tire. The front right would not balance. They ordered a new tire and put the bad one on the rear. Vibration stayed the same even putting the bad tire on rear. Nothing through the steering wheel.
New tire comes in. Mounts and road force balances great. Test drive- same vibration after new tire.
My friend has a JL with 37” bead locks that doesn’t vibrate on his JL. Swap wheels and tires to my JT to see if it’s in my wheels and tires.
Vibration is worse with his wheels and tires. His wheel and tire setup is 12 pounds per corner heavier.
Conclusion - it’s not my wheels and tires. The heavier weight of my wheels and tires over factory is amplifying a driveline issue.
It’s currently back at the dealership.
Looking for any kind of ideas and input in possible issue. Bent axle, driveshaft, etc...
Jeep has 6000 miles on it.
