Help Death Wobble -- '94 F350

Sorry the long read.....

Two wheel drive, LWB, 7.3L diesel.

Headed up to Aggieland Sunday morning. Making the entrance from I45 onto 610W, in the middle of the curve I thought the front end was going to fall apart. About gave my wife a heart attack. Had to almost stop before it quit wobbling violently. Same thing happened twice more when taking the curves at each corner of 610. Everything is fine until I hit a significant curve in the road then all &$^^ breaks loose. No frontend vibration, etc. except going around curves.
Did some testing on the trip home (wife stayed overnight) and discovered that if I don't decelerate the wobble isn't 'too bad' and even improves somewhat if I accelerate.

After looking things over briefly Monday morning it appeared my front tires had some 'ridges' in a couple places and the tires have quite a few miles on them so had all new tires put on. Went for a test drive and same thing.

Jacked up the front end to check tie rods, tie rod ends, ball joints, etc. Everything in the front end is tight. Zero play anywhere. Had front end aligned about two years ago as I had some wear on outside of one front tire.

This has me stumped. Any suggestions/ideas/etc????

Common problem on the Fords. I dont know anything about it, but I know there's folks on here that had the same issue. They'll chime in

Mainly happens on curves to port too huh?

Replace the steering stabilizer (Steering shock absorber), they go out around every 200,000 miles or so.

Death wobble in the old Fords is a bushing issue. Replace them all.
Cant remember if the two wheel drives have a trac bar but the trac bar bushings are almost always the culprit. Otherwise just get after all those other bushings. Cheap to replace yourself just a lot of work.

Everything else is like steering stabilizers and trying to tighten steering gear box etc is just masking the bigger issue and will wear those parts faster. Start replacing those bushings.

No track bar, the 2WD front ends are independent suspension. Everything must be work out if you have death wobble with ind suspension, it usually happens with 4WD truck with a solid front axle.

yep i couldnt remember ......
...... start replacing front end parts. Ball joints and arms and bushings before it eats your steering gear box.

Rotate and balance tires too. See if the issue follows a tire.

Thanks for the feedback guys. My initial thought was to replace all/most of the front end parts due to it's age but was hoping there was something specific to address. Did ball joints a couple years ago so one of the toughest jobs is already out of the way. I need another project to keep me busy during this cold weather.........right.

Harbor --- I thought the port curve was the primary problem until I came to the starboard curve heading west on 610 south at Post Oak and found out differently. lol

Steven -- new set of tires Monday morning.

As in you just got new tires? (Maybe new tires created a new problem if not balanced correctly)

Or scheduled for new this coming Monday?

I feel your pain

I have an 2008 F250 4x4 LWB. I tried everything. Track bar, twice replaced, helped for a little while, tie rods - no help. Eventually replaced everything at once on the front end. Have not had the wobble since. At the time of replacement everything seemed as if it was "tight", but after replacing the upper & lower ball joints, tie rods and track bar the death wobble has been defeated.
