Hello, having trouble diagnosing a vibration I am getting in my 2011 XLT, 4WD at 65mph+. I can feel the vibration mainly in my seat, but ever so slightly in the steering wheel too. No tracking issues, and no issues when breaking. The truck only has 29,000 miles on it, but the PO had said it sat for awhile. First thing I did was a tire rotation and balance, no change. Tires have good tread, no uneven wear. Since the vibration was in my seat, I focused on the rear end first. I jacked up the rear end and put it in drive, the rear driver side tire did not spin. Even though breaking felt fine, it ended up being a clogged line. Replaced all break components in the rear: lines, rotors, calipers, pads, and parking break shoes. Front breaks looked fine (appeared to have new rotors and pads), and did a complete flush. No change in vibration. Then changed rear axle bearings and seals, no change. Then replaced rear driveshaft u joints, greased the slip yoke, and replaced both yoke flanges as one had broken around where the retainer clip groove is. Again no change in vibration. I then read up on forums and road force balancing was mentioned a few times, so had this done. 2 of 4 tires were way out of spec when the tire shop did the road force balance. So I ordered 4 new falken wildpeak A/T tires, had them installed, and I would say about 50% of the vibration is gone. So looking for suggestions on where to go from here.
