Interesting enough my 07 F250 4wd had the same issue when I bought it used 4 years ago. Drove me nuts. Only happened after hitting a rough section on the interstate a speed.. Slowing down to 40/50 mph brought it back under control. Steering stabilizer helped but did not cure it. At a friends shop we went under the truck and inspected every darn nut, bolt, suspension part, etc. We noticed that the tires were underinflated by 15lbs. Don't know how that happened BUT, inflated to the specs that Michelin recommended for their tire. Amazingly enough the death wobble has not come back over the past 18 months. Don't know if we cured the problem or just masked it. Now to the weird, a few months afterwards there was a bulletin put out by Ford addressing this issue. One issue pointed out in the bulletin was proper tire inflation. Food for thought.

I got a dual shock steering stabilizer i’m going to install tomorrow night. I’ve had a few fb messages suggesting tires as well. These are factory tires still so maybe something has worn enough on them even though they look fine. I’ll double check the pressures with a real gauge but the on board tpms shows them to be close to the 60 front and 65 rear as recommend on the door jamb sticker. I need the truck daily for work but i’m paranoid every time i’m up to hwy speeds now. Too much traffic in this town to have to be slowing down to 30 with no warning on the freeway.

Is this primarily a diesel issue because of the weight on the front? I have a 2011 gas 4wd and it does have a single stabilizer on it. It was worn out when I bought the truck so I replaced it. Steering feels much more secure when hitting bumps going around corners. Just curious if it is more about diesel than gas trucks?

My neighbors truck with the problem is gas not diesel.
Proper tire inflation is what is on the door sticker for the vehicle.
I have another friend with an F250 diesel and his problem is body mounts disintegrated and the cab is down on the frame.

Just to let you guys know there is a new steering shock with a engineering change coming hopefully we will start getting them next month and fix your guys trucks.

In may case I have an F-250 Super Duty 4wd 6.0 diesel.

Check the track bar joint at the axle I bet its loose.

I had this a couple of times with a 2000 F350 but it normally occurred when hitting a dip in the road or pot hole with the right front. I just recently rebuilt the entire front end and the most damaged part was the upper right front ball joint. At 150k, it was totally shot. The OEM stuff is sealed which I personally dislike - heavier trucks should be equipped with grease points for maintenance reasons but I guess you add up the cost of 4 zerk fittings on 100,000 trucks and it's money saved.

My old 81' Chevy never did this....not once, even without stabilizers...both at stock height and after adding a 4" lift and 36" tires....

If they are wobbling, it's a steering linkage design and alignment angle issue that needs to be addressed. Stabilizers are a bandaid for a bigger problem....One of the reasons I'll NEVER own a ford......I used to make plenty of money working on them though......

While it's money saved, it's customers screwed! One doesn't have to wonder why aftermarket, or at least quality items, have zerk fittings. Of course the lack of zerks is directly attributable to the "green" movement. My motorcycle is supposed the have the rear suspension and head tube serviced @ 20k mile intervals. That means removing the rear tire and swing arm to lube the pivot points. I did it ONCE and drilled and tapped as many points as was possible. So now I can avoid a $300/$500 dollar service bill with about 10 pumps of the ole grease gun. While it's likely a government mandate it could just be the manufactures bowing to green. Either way it gets the mfg. out of warranty period and the enduring customer gets bent over big time.

Yep - I agree completely. All the stuff I put back in the truck was the best I could find and every joint has a fitting now...course I'll probably be under there for an hour now....LOL
