Iv got that bad vibration

[JWillms]

Well its been 1 week after I installed my coil spacers and its been riding just like before, then last night I was driving threw a section of highway that was under construction so they wernt the best roads out there, when the truck started bouncing up and down kind of like driving over those big round bumps in the road it was horable. I just shook it off as being part of the road then it happened again still just shook it off as part of the road. Then it did it again after the construction site. I pulled over to give it a look over and everything was fine from what I could see then it didnt do it the rest of the trip or the way back home down the same road. I have heared that there is a vibration problem on some of these trucks but this isnt a small vibration like eveyone else has seen this shook the hole truck (made the trailer tire and box of fruit slide my bed mat forward). Im going to go back and look at it again this afternoon see if I cant find anything else.

JWilms, you experienced the "Death Wobble" and there are a couple threads lately talking about this. It's a 4x4 phenomenon.

Thanks Vaughn I knew I have heard of this happening but I could seem to remeber where I heard it. Thanks

Sorry to hear you've got it too! I've been in the middle of an extreme case of "Death Wobble". STILL waiting parts that dealer says is causing it. They replaced the front left hub and bearing assembly and are now going to replace the arm that runs from the pitman arm to the tierods. Mine occurred just like yours and has progressed to the point that I can't drive over 40 mph without the wobble starting and it gets so bad that if you don't slow down rapidly it will throw a cup from the cup holder. Ironically there is a stretch of highway under construction that I first noticed mine on. I put the 2" spacers on, 315's and drove for 15000 miles before having any hint at it. I'm not sure if that's the cause, but I wouldn't think so. Check out my thread "Scared to Death" and Good Luck..... all I have had is bad... ... bad enough I MAY trade! I've got 22500 miles on my truck and it's just over a year old... ... ... the wife will freak and I will be sick, but I use my truck daily as a work truck and CAN'T be dealing with down time... . that's why I bought another Cummins!!!

For what it is worth, I had a 2 inch Rancho lift on a ford 350 and if either front tire was out of balance just a little, I would get the "Death Wobble". I mean I thought the front end was going come apart. I would have the tires balanced real good and the wobble would go away. My 2 cents (truck was a 2X4).

They have balanced, re-balanced, moved the best 2 tires (least amount of weight) to the front, and NO improvement, but thanks for the suggestion. I hope that solves the problem for others though.
