Here's mine...2014 All Terrain. The photo was taken with my drone.

Mine is a 3.42 All Terrain. Not a bad ratio.

My drive shaft was both out of balance and not straight. After addressing that at Advance Driveline, there was a significant improvement. The dealer still says I have three bad tires (after Firestone replaced them four times - changing brands as well). Firestone checked them again, and reported that they disagree with the dealership's assessment (of course). I think Firestone is correct. I don't have a wheel hop. I have a high-frequency, very mechanical, vibration.

I actually still feel Firestone has stepped up. I have no problem with them. I stopped in to a totally different location for an alignment check. They looked at my history, re-aligned, rotated, indexed and balanced my tires again. No charge. Vibration still present, but not eliminated (again, this is after a substantial improvement from the drive shaft re-balancing/straightening). I went back to the dealer again. They said I have 3 bad tires. So...Firestone, who has invested a lot on their dime (3 sets of tires, including a brand change from Destination AT to Revo2s at no charge, plus multiple alignments, balances and indexes) thinks they are dialed in. The dealer says (again) I have bad tires. It should not be this hard to balance tires on a truck. I've had multiple trucks and SUVs during the past two decades. On most, I've had either Destination ATs or Revo2s. Rarely any issues...(Ford Expedition, Nissan Titan, Toyota 4Runner - previous vehicles). The dealership blamed the tires and charged me for the vibration investigation last week. I've decided I will replace the tires. I'm going to buy them from the dealership. And if there is a hint of vibration, They will own the problem. And since I'm under and extended warranty, I'll ask for reimbursement for all of the vibration related work I've had done that they blamed on the tires. I have a GM case number, and will also copy them on it.

I'm new to the forum (bought my truck in August 2016). Having been active on previous forums for previous vehicles (Nissan Titan from 2006 to 2010, and a 4Runner from 2010 to 2016), I sought this site out pretty quickly. I'm experiencing the vibration issues as well. I bought my 2014 truck last August. It was a 24 month lease return - perfect condition. But the vibration problem is bad, and like chasing a ghost. Steps I've taken: Multiple dealer visits Bought new tires one month after buying the truck (Firestone Destination ATs - tires I've had on 4 previous trucks/SUVs) It shook uncontrollably - Firestone replaced the tires 3 times - the final time changed brands to Bridgestone Revo2 (BTW, super Kudos to FIrestone...they covered all of this thinking it was a tire problem) Took it back to the dealer - I told them I suspected the drive shaft, or another drive train problem They said that wasn't the problem - explained it is the "frame harmonics" I took the truck to Advanced Driveline - the drive shaft was WAY out of spec - off center, out of balance and not straight...other than that, it was well made Still some vibration - but the drive shaft repair helped Having the tires rotated, balanced and alignment done tomorrow. If that doesn't work, I'm riding the warranty until they glow in the dark. Somewhere down the road, I'll probably go the the Ford dealership to check out the F150s.
