Brand new Lariat ER Truck-rough ride, shuddering under acceleration, thoughts?

[LakeWorthLuke]

It sounds like the imbalance may be caused by a bearing issue. It’s possible. Don’t stop complaining. The truck should be silent and smooth. The further you go down the road like that can make it worse.
Good luck.

Thanks! Yes, Im definitely concerned something is bent or defective.

I have the shuddering just after accelerating to 70-80kph. It shudders after the acceleration and goes away in about 15 seconds. It is usually after coming around a corner and accelerating moderately. This is the post for that.

So far I am not aware of a solution.

Right! I read that all, sad to hear it still doesn’t have a solution. I’m definitely going to push for new tires, it’s 8 months old, been sitting on Ford’s lot all that c time and the tires were underinflated which is crazy for a 8500 pound truck!

But that is only one problem, the suffering was terrible yesterday using 1 pedal and Sport Mode, so at least the dealer will be able to see it.

Let me know if they find anything. There were issues with some 1/2 shafts but it doesn't seem to be that for me. It seems more likely that it is an issue with the traction control pulsing in specific conditions. I notice it is worse when the roads are wet.

For reference, mine is an early 2023 model built 11/22. Yours was built 16 months later. Besides the shudder, mine is perfectly smooth, perhaps even too soft for my liking so your rough ride isn't normal.

OP, take the truck and turn your steering all the way left and drive slowly. Do the same thing as well with the steering turned all the way right. Do it multiple times on a road that isnt perfect, where you will drive over divots and the like. Are you able to hear any clicking or creaking?

Tried that, no it is quiet! But I did feel something going around a right bend in a road yesterday doing 40 mph, something definitely not right with the front drive

I know someone who accidentally switched on the locking differential... and...that.
