Death Wobble?

[dragan54]

Not sure if what has happened on a few occasions the Death Wobble. Happens always at highway speeds. It to be caused by washboard concrete or a bump off a bridge. it feels more like the wheels are jumping up and down instead of a wobble. The truck has 150,000 and ball joints tie rods are replaced for the third time. Tires have maybe 20,000 on them. Just replaced shocks a couple months ago and added steering stabilizer.



So do I have it? If so what is the first fix and so on



Thanks

If the tires are BFG A\T's they normally start to show there soft sidewalls around 20-30k causing DW. I'd check the track bar bushings and bolts too

The fix for my 03 was the upgraded steering linkage.

Check castor angle. Needs to be 3. 5 degrees or more.

What shocks and what ball joints did you use? What tires and size? Not all created equal.

Need more info.

 

[dragan54]

Tires are Goodyear Wrangler 245 70R17 and the shocks are Rough Country

Thanks

Ball joints and tie rods are from NAPA

Do you have a lift or leveling kit? Replaced the track bar bushings lately? How is the general driving characteristics? What are the alignmnet specs it is set at? What load rating are the tires?

 

[dragan54]

No leveling or lift. Track bar bushing not replaced unless it was done when the ball joints were done will ask Monday and getting alignment Monday. I will pass on what I find out

Thanks

One more thing to check for with the Death Wobble... . Tire pressure. Added 15 pounds to right front and it stopped!!!!

With stock size tires all the 3rd gen front specs have been raised to 60psi on 4x4s

The door sticker on my 09 says 65#. It's been weighed. 65# doesn't leave a lot of leeway.
