So i have 2022 Lariat 4x4 with the 3.5 Ecoboost and i have a slight but constant vibration at or above 75MPH. I know the first thing people will say is tires. Well that's another story too...i' put BFG KO2 on at 2,000 miles and i drove on them for about 15,000 miles before i decided to start looking into possible issue with tires vibrating. I found out that one of the BFG tires road force balanced marginal. BFG would not do anything so i sold them to a co worker who was aware of the issue with the one tire and i bought a set of Falken Wildpeak AT3W. The vibration was still there but worse...long story short ended up going through 7 Falken tires before we got 4 to pass a road force balance but there was still a slight vibration. Ended up returning the Falken tires while i could still get my money back and put a set of Yokohama Geolandar AT G015's on today. Things are better but there is still a slight vibration enough to make a car seat in the back rattle at times. Tire shop is saying that the Yokohamas all balanced out good with the highest having 15lbs of road force and the lowest being 10lbs of road force. Tire shop is telling me to go see Ford about potential driveline issue causing vibration. I haven't research road force balancing enough yet to be able to interpret the lbs of force to whether or not the tires are good and properly balanced. I've spent a bunch of time and quite a bit of money over the past few weeks trying to get the vibration gone thinking it is the tires but i'm beginning to believe it may be something in the driveline. I feel like Ford is going to blame aftermarket tires and the tire shop is going to blame Ford and i'll just be stuck in the middle running back and forth. Anyone else experience a similar situation or can shed some light on the road force numbers that they provided me? Thanks in advance!
Forgot to mention it seems to smooth out a little bit when letting off the gas and then vibrates again once i'm back on the gas pedal or using cruise now that the Yokohama tires are on there. This to me would suggest powertrain (engine/transmission) issues and not the tires. I did have TSB 22-2224 performed yesterday at the dealer to try and take care of low speed low rpm vibration/shudder.
