Death Wobble between 40-50 mph sometimes

I got a 06 with a 6" lift and 37" BFG All terrains that i purchased as is and sometimes between 40 and 50 it will get this really bad shake, the steering wheel is out of control and you have to slow back down to like 20 to get it to stop. Someone told me I need to relocate the track bar. I had the tires balanced to day and it still does it... Another person said hubs??? any insite into this??

How are your steering stabilizers? Make sure your trac bar is tight!

type in superduty death wobble fix in google, theres a company in Massachussets that makes the trac bars that correct the problem. There about $850. It uses a solid mounting point not a ball joint like the stock one has. Guaranteed to fix the Super Duty Death Wobble!

heres the company:

does it do it all of the time or is it hit or miss? i have an 05 with a 6 inch lift and 37s and it does it once in a while when i start braking and didnt know if this could be the same thing or not.

Trevor at Precision Metal Fab makes one for alot cheaper. His also replaces the "ball joint" with a solid type joint. The bar is also adjustable.

Give him a call, he will be glad to help you out.

+1 on Trevor's track bar. Nice solid piece at about half the price of the WCM bar.

Check castor..lifted trucks should have more than stock specs..5*+- good start. Also check your unit bearings and ball joints. Check your track bar bushings and also tightness.

Thanks guys, I will check things, I have checked the pitman arm and the steering stabilizer and they checked out fine, I had the tires balanced to see if they were messed up and surely they would have said if the hub bearings were shot... The truck only has 106K miles, and its running 37" BFG all terrains so I dont think they would do much damage as far as rough riding, My 2000 lasted 130K with 30K on 38" SSRs and 8K on 49" Iroks

It is hit and miss, mine does it accelerating up into 40 and does it sometimes when I hit soem bad bumps in the spees of 40-50.. It totally sucks... I made my own trac bar for my big orange truck pictures so I damn sure going to do it myself before i spend 550 bucks.. someone told me they had a fix for around $180 But I wanted to see what some of you other folks were experiencing
