Thanks for the info. Please keep us posted after the spring change.Took delivery of an OT in Oct. Now have over 6k miles. What seems odd with mine is sometimes I have the vibration and other times not. Over New Years I drove from Colo Springs to Tucson. I noticed driving out of Colo Springs, the vibration was pretty noticeable around 70 to 75 mph as has been the case since I got it. If I noticed that when I drove at 80 mph, it smoothed up. I stopped in Albuquerque to eat and afterwards when I got on the interstate, it was vibrating badly at 60 to 65 mph like it never has before. So I accelerated to 80 for awhile and then the bad vibes at the lower speeds returned to normal vibrations. I suspected at the time that the BFG KO3 tires may have had a temp flat spot formed while eating. But throughout the rest of the trip, I never experienced that bad vibration again even after similar stops from interstate speeds to eat. It did seem coming home that the vibes weren't as bad. In the past, I have had two 4Runners (4th and 5th Gen) dnd never had this kind of vibration. In summary, the vibration comes and goes. Puzzling to say the least. I will soon be replacing the rear springs with heavier Dobinson springs as I am adding a Victory 4x4 rear bumper with spare tire carrier and will be towing a 5000 lb off-road camp trailer. Curious to see if these changes affect the vibration experience. (BTW, changing out the stock Toyos that came with the OT with the KO3s Load Range E tires did not affect my vibration experience - tires are not the cause IMHO)
