Hey everyone,
Looking for your insight and experience here. 2020 XLT FX4 super crew with 34k miles. No mods - all stock.
Over past 1k miles noticed two separate issues:
1) truck vibrates at 70-80 mph, both under power and while cruising/coasting. Same experience whether using cruise control or not - smooth roads or janky highways - felt in body of truck, seats vibrate, steering a little. Truck was recently at dealership for this - had alignment and balance done- was not resolved and I was told techs couldn’t replicate, which makes me wonder if they actually drove it.
2) shudder/vibration when braking - but really only when going downhill - I travel a lot through mountain areas, and on paved roads when decelerating from 45/50/55 feel a shimmy/shudder coming from rear of truck. Feel it in brake pedal, not steering wheel- thinking rear rotors. At dealership they shave off a small increment from rotors, but this has had no effect and issue still present.
So- looking for your thoughts. I’ve read through forum posts and see an issue with vibration at 75mph resolved by new tires. The current tires (Dynapro ATM 265/60R18/110T) still have reasonable tread, and have been rotated with each oil change at 5k….
Braking issue- could it be as simple as rear rotors needing replaced? But what would cause/lead to a warping in rotors?
Especially at only 34k miles?
Thanks in advance for all the help.
