Just bought my first Super Duty its a 2018 F250 ccsb. I used a redilift leveling kit with track bar a dust and nitto 35 12.50 20 tires. Love the truck drove it 300 miles to Nashville. I have a vibration that is felt mostly in the gas pedal when giving the truck fuel from 60 to 80 mph. Almost feels like pinion angle vibration. Has anyone ever felt this.? Will be taking it to my dealer when I get back home just looking for anyone experienced in this issue. Thanks guys

 

Could it be the tires, or were you already running them before the leveling kit and had no vibrations?

 

I though so until I realized it is only when applying the throttle. As far as before tires and level I don't really know I had tires and leveled installed before I bought it with 5 miles on it.

 

Hey Wingmen did you ever figure out what the vibration was.

 

Off-road tires like r/t or m/t will not ride like factory. It may cause a rougher ride, ie some vibration.

 

sounds like wheels/tires out of balance.

 

 

 

I have the same problem. Slight vibration between 60-80mph primarily when accelerating. I can coast at those speeds and the vibration is pretty much gone. It's not tires and has nothing to do with leveling.... either by lowering the rear or raising the front. I thought I had mine fixed by installing the 1.5" PMF blocks with 2.5 degree taper, but it still vibrates some mainly between 60-80 mph. I did install airbags, but no matter how high or low I adjust the bags it still vibrates. It's somewhere in the drivetrain.
I can live with it, but I shouldn't have to on a $70k truck. My wife doesn't notice it. I'm taking mine in to the dealer this week to have Frontier bumpers installed front and rear. While my dealer is my brother, I still don't have much faith in them finding the fix.....I've read too much about it on the internet with no solutions.
Has anyone had their driveshaft balanced? Just wondering. Because it is more noticeable under acceleration than when coasting it's probably not a driveshaft out of balance problem.
I'm expecting it to be worse with a trailer. I'll find out this week.

 

 

Does anybody have any updates on what might be causing this vibration ?

 

Have you gents tried carrier bearing shims/spacers?

 

mine did the same thing, ended up my ready lift traction bracket was loose. might check yours and see.

 

You torqued everything as directed and it still came loose? Guess I will have to get back under there and check everything.

 

I had this. My caster was at +0.4 +0.9. Switched the bushings and got it to +3.2 +3.6. Now i have no vibration.
