"Death wobble is a result of worn out/broken parts." Not true! Everything in my front end is new and I just had it aligned and tires balanced. 200 miles later, I got my first DW Friday when I hit a pothole. Craig

Some points:

1) What is YOUR definition of death wobble, then?

2) You say, "Not true!"
Please back up that claim so we all can learn.
Your point tells us nothing that re-enforces your claim.
I smell a huge assumption on your part.

3) Is literally EVERYTHING that affects your front suspension and steering system new?
IS THE RIG NEW???


My 2012 Super Duty has 213,000 miles on it and it still has all original suspension parts except for shocks. My truck experienced the DW scenario twice in close proximity around the ~80k mile mark when I was running BF Goodrich AT tires when they were about at the end of life. Once I changed out those tires to a different brand it hasn't happened since.

First you say, "Everything in my front end is new" (at 213,000 miles???).

Now you say, "it still has all original suspension parts".

WHICH. IS. IT?????


213,000 miles:
1) Has the wheel bearing been checked AND repacked/replaced?
2) Has the steering box been checked; specifically at the steering arm/sector shaft?
3) Has ALL steering linkages been inspected at the zerk fittings?

If any mods to front end/suspension:
4) Has ALL mounting hardware been checked/retightened?

OP, what are these “increasing signs?”
In my experience and everyone else I’m aware of, it either happens or it doesn’t.
There’s never like an “almost” death wobble.
Yes heavy duty steering dampers can “help.” But as said, they are a band aid not a cure.
Since you don’t provide any other info, we cannot make any other educated suggestions.
As far as shocks go, ( and steering dampers), they don’t have a set lifespan. If you can’t tell whether your shocks are still good, then I suppose there’s a 50/50 chance they are good or not and you’re used to the way the suspension reacts.
Best bet is a mechanic although it is one of those issues that can have many different causes ending in the same result. From worn parts, (Track bar bushings are a big culprit), to lift kits with poor geometry, to alignment issues, to tires.

Interested to hear what you think the impending symptoms are...

New ball joints and tie rod ends and the slack was adjusted out of the box. I asked the aligner to double check everything. The steering felt great. I went to eastern Co for the week and coming back I was changing lanes and watching the mirrors and wham, a big pothole that set off the DW. I've had a high speed wobble on a motorcycle and it was exactly the same... Slapping lock,to lock and it didn't stop,til I was nearly stopped on the shoulder. I had it up on stands today and everything is tight but I ordered a new stabilizer. BTW, Dodges are noted for this. Rough bridges and bad roads were fine til I hit the hole on one side.

Thanks Walaby for pointing this out. I have to say I forgot about replacing the passenger side front wheel hub/bearing at around 150k miles, but that was way after I had a DW experience.

Since we lost ageslaius at steering dampers, never to return again, steering dampers and shocks are effectively band aids. Not the cure. Period, end of story.
But then again not sure what OPs issue with the truck is, as he was cryptic in his message and then never posted back. Not interested in opinions on the subject past the bandaids.

OK last March we had the right front hub replaced for the second time. The shadetree mechanic would did the first replacement bungled the job.
Anyway we started hearing a rattling from that side. But also the left front start a serious shaking whenever we hit even a small bump at over 35 mph. That has got progressively more violent. So bad that I have to slow way down when it starts now to stop it.
Trucks going into the shop Tuesday, the hub is under warranty and I asked them to carefully inspect the rest of the suspension. Truck has over 160K now. I put in Bilstein front shocks and a steering damper but that was quite awhile ago, maybe near the 100K mark.
I have a lot of faith in this mechanic shop which has been in business since the 1980's. They repaired a hose problem on the turbine and the front hub in a day last time I had the truck in.
