Nuisance Vibration
Alright Brain Trust,
Situation for the Day...
Stock 2015 F150 5.0L Lariat, 4x4, crew cab, 6.5' bed, 124k miles. I have a nuisance high frequency vibration that has been going on for at least 4-5 years. The vibration occurs between 60 -72 mph whenever the drivetrain is under torque. Truck cruises fine >75 and <55mph. You feel it through the seats whenever the truck is maintaining speed, accelerating or decelerating. Vibration goes away momentarily when you let off the gas before the truck starts decelerating or at the crest of a hill when the cruise control allows truck to coast before drivetrain drag kicks in on the downhill side which brings the vibration back. All rear drive shaft sections have the tack welded weights intact and the bearings and bushings appear secure. Vibration occurs at the same speeds regardless of engine rpm.
Any thoughts as to the cause of this vibration?
Thanks Charles

I had a similar issue with my 2016 F150 XLT with 5.0, 6 Speed, 106K miles. My solution was to trade the truck on a 2025 F150 w/Lobo Package. However, I just read a post on this forum describing a similar problem that mentions torque converter chatter and suggests the repair is $1500 to $3000.
