Severe front end shaking

I just bought a 2016 Ford F250 Super Duty gas earlier this week. Yesterday early in the day and today late in the day I'm driving on the highway and it seems when I go over a rough patch in the road that the entire front end shakes so bad that it's like a tire is fixing to fly off of my truck and I'm just wondering has anybody else dealt with this what the problem may be anything will help thank you

Okay newest update after doing some research today I have found that they say according to a master technician for Ford that adding a dual steering stabilizer dampener shock kit completely removes the death wobble from the Ford F250s and F350s.

Everyone saying it’s worn steering components and ball joints but my truck was a couple months old and less than 5000 miles when it started. Nothing worn on a truck that new. There are videos on YT of guys pulling out of dealerships in brand new trucks, hitting a pothole, and the death wobble ensues.

I honestly believe it has more to do with Ford not matching the coil spring rate with shock compression and rebound rate along with next to no caster. I say that because all I did was a leveling kit and BOOM! All fixed. 185,000 miles later and it never has happened again. I’ve since replaced many steering components that was most certainly worn but never got death wobble while those worn parts were along for the ride.

Start here.

Ok so installing these Carley Ford Super Duty Caster correction Sims do I need one set or two sets or how many do I need that says a $75 for a set

Alright, there's a lot of varying answers, but I'm not seeing a few big and important questions being asked. Is your truck 2wd, or 4x4? how many miles on it? Your first thing to do, is get the front end off the ground, and see if anything feels loose when you try rocking the wheel up and down, as well as side to side. Then, if you feel movement, it'll be a little tricky, but you'll need to determine what is causing said movement. Another item not mentioned is improperly balanced tires. This can also compound your issues. As can very badly worn and cupped tires that can create and amplify a lot of vibrations.

The caster shims are great, but that's something that REQUIRES an alignment immediately, as every change to camber/caster (and they do change both) also changes the toe angle of the tire.

I want you to understand, this isn't rocket science, but it CAN get complicated and stabilizers aren't a fix at all. I owned a Jeep on 36's and deleted my stabilizer entirely. I didn't feel even a HINT of difference. Not one. They're honestly not useful at all. That's money better spent on diagnosing the issue, and fixing it. Not putting a bandaid on it.
Thanks. Its a 2016 f250 lariat 4x4 with 121k miles

Knowing this, I would say have the balance checked on all 4 tires, as that can definitely cause issues. Then while you're at it, a good thorough inspection of the entire front end. Tie rod ends, ball joints, track bar (this is a big one, my boss's 2018 had this, and it was a mystery until we found it) and equally important, the U joints in the front knuckles. If those aren't good, it can cause some strange and funky stuff too. So can just general bad U joints on drive shafts.

Ase certified input, from a guy whose forte is suspension and anomalous vibrations in vehicles. I'm quite good at it too, except on Jeeps, where the only fix is to live with it, or throw the whole GD thing away.
Ok thanks
Sounds like its gonna cost out the wazoo but im stuck with it now. So do you think after an alignment i should install a dual sterring suspension dampener and or shims

I absolutely agree that these are basically Ford's bread and butter, especially to fleets. So premium quality isn't the thing, although it should be for what we are forced to pay. That's another whole separate discussion though.

Now professionally, I disagree on caster being the "magic item" however it will help substantially. BUT, and this is the big thing. It will not help no matter what if you've got bad parts that need to be replaced. Therefore, diagnosing, and addressing worn out components is the ultimate magic item here in my experience. Really let's just say a GOOD mechanic, and the right settings really is the magic item here. I mean good, as in a mechanic who knows how to find the issue, and what he or she needs to adjust to what setting to achieve the result.
Wow guys i rwally appreciate all the info. I dont suppose you are close to dallas by any chance?

Ok. First of all I want to thank you all for the feedback. So i got my tires balanced and rotated, and an alignment. So far the wobble has not returned. Even though im still leary about when it could or will do so again. I am appreciative of your insights and knowledge as you all have saved me a chunk of money.
