My 2001 Diesel has developed a death wobble...sometimes after turning, the steering wobbles as if on a cobblestone road. Sometimes it pulls to the left and then completely sets sail to the right. I have replaced the wheel bearings, the steering stabilizer shock, the gear in the steering column...nothing works. It can go for two hours and then it happens. Once is goes, you cannot go over 30 mph without losing control. And then I stop, and it's gone. So frustrating as I use this to haul horses and I cannot trust the vehicle, and no one has been able to diagnose it.

 

What's the tire pressure? IS it at the stated pressure? YOu MAY need to install an additional aftermarket stabilizer.
Have you let the Ford dealer look at it?

 

The dealer has replaced the items mentioned, and then sends me off, and it continues to happen. I've been there three times. I will go home and check the tire pressure--it would be nice if it where that simple!!!

I'm having a similar problem. Replaced a few components as advised by a ford mechanic. Finally, I jacked up the front end so the wheels were off the ground, I then turned the shaft going into front hub while checking the u-joint there. The tire wobbled as i turned the shaft. I'm in the process of repairing it now so I can't tell you what the problem is. I do know the hub that is suppose to turn from free to lock is not turning and is hard to remove from the steel hub. I'm searching for hints to remove it.

 

The death wobble problem is really only on the 2005 up trucks with coil front suspension.

That being said you definitely do have a problem, just no tdeath wobble.

Have they looked at the steering gearbox to make sure it isn't worn out? Have they checked the balljoints? Tie rod ends? These are all somewhat common problems with the Super Duty trucks that may be causing your issues. There are other guys here a lot smarter than me though, so we will see what they say.

 

+100 of what beerstalker said

i would say the ball joints and tie rods cause my old dodge i had this this exact same thing. it ended up being both upper and lower ball joints on each side was bad and i had bent tie rods on my pass. side of the truck.

 

The gear box has been replaced as well. Today the front end is getting aligned and the shocks replaced. Could it be that the replaced wheel bearings may be faulty?

Had the same problem with a 2000 F-250 after we lifted it a few inches. It turned out to be the track arm bracket where it bolted to the cross-member. The truck would be fine; then when you would hit a bump it would wobble your teeth out! The bolts seamed tight but once we torqued the heck out of them the problem went away. Not that your's is lifted but the bolts/track arm bushings may be the cause.

 

I had my front wheel bearing go out and it never shook, so I doubt it is that. I would go with what others have said: Ball Joints or Tie Rod Ends.

Do you have oversized tires?
May need a aftermarket Steering Stabalizer??? The stock ones are junk.

 

Have them check the balance on the tires also. I have had a problem with losing a wheel weight before doing this type of thing.

 

Could be a broken belt in one of the tires, but seems like it would do it all the time.

 

I'm a jeeper. Here are the primary causes of death wobble:

1. Caster (not in correct adjustment after a lift)
2. Loose track bar
3. Worn (soft rubber) bushings
4. Ball joints
5. TREs
6. Tire balance
A steering stabilizer has nothing to do with death wobble and will never correct it. Most folks in the know (of us jeepers) don't even run stabilizers.
