I do have over-sized tires. But I have had them on the truck since I first purchased it back in 2010 with no issues. There had been no new changes on the truck for at least a year before this problem started. There has to be something wrong in the suspension system. I was hoping someone else has had the issue and knew the fix. I see a lot of videos on the Dodge death wobble that I thought could be it. But after watching the death wobble in action thats not what my truck is doing. Unless mine is just in the early stages and most people don't notice it.

 

How are the tire pressures? (don't 'assume' they are ok, check 'em.)

 

Those tires from factory are junk. put some LT tires and you will see a big difference

 

The tire pressure is spot on. I have BFG KO2's in 35 inch on the truck.

 

What load range, what wheel size, and what pressure?

 

The tires are BFG K2O's 315 70R 17. I have the pressure set at 40 now but when the problem started they where at 36 and no change. I know this is set lower then what the door sticker says but I was told to do this from discount tire. I guess when I bought my BFG's they where changing the look of the tires and didn't have my speed rating in stock so they bumped me up to the next speed rating. I can't remember what this is off the top of my head.

 

If you have a bad shock absorber on one corner, or definitely opposite corners, you could get that effect.

[edit: Oops, I see you already stated those were replaced and I don't see a way to delete a post]

Check the side of the tires, should tell you what max inflation pressure is.

 

So now I have replaced the Front struts, Rear springs, Rear shocks, front sway bar links, front sway bar bushings, rear sway bar links, and the rear sway bar bushings. Still having the problem. Has anyone else out there experienced this or know some one that has or has a solution. Can't find anything on the net about this problem.

 

Is it actually the suspension that is doing the see-saw? Have you checked to make sure the bed is still attached to the frame properly?
