    Death Wobbles

    Has anyone had the death wobble problem. I have a 2006 F350 Superduty, Crew Cab, Short Bed with a Pro Comp dual Coilover 6.5 lift. Above 55 mph or so when I het a bump it goes into a crazy death wobble. I have to immediately hit the brakes and hold it straight until it subsides. I've taken it back each time I start having the problem to the guy who installed it. He tightens up the big nut on the driver side up by the frame. It causes the problem to go away for a short period of time. Does anyone have a solution for this problem???????

    Need to get rid of the stock steering stabilizer and go with a Pro Comp dual kit. This will help, but Castor adjustment is prabably the problem. Go to a good alignment shop that does big lifted 4x4s and have them check castor. Make them put it on the rack with the computer, you can't do this on the floor. Castor angle correction is the biggest thing for good and safe control when you go up on a late Superduty. Are you 4linked in the front? and is it adjustable? or you may need cams put in your front rad. arms to correct.

    I have the Pro Comp Dual Stabilizer on there. I will try the alignment. The kit came with their pitman arms. Not sure about 4 linked?? Any recommendation on a good alignment shop?

    I'm down in San Diego. 4 wheel Parts?, watch them real close and make them back it up. Where ever you take it get a printout of the alignment as set, for future referance.

    Hit up ORW in Clairmont. They do all of my work, and they got rid of my death wobble. I'm running 40's. I believe it was the cam bolt.

    If your tires are cupped or worn funny then rotate them. Ive had the problem on other trucks if they were worn funny or almost bald then thats part of it. Stabilizers arent always a fix they are a bandaid. because i put duals on my 97 and it helped but did not cure, moved the two tires on the front that were cupped and it was gone.

    My truck is doing the same. All stock suspension. It doesn't do it all the time. I'm usually going 80 hit a bump usually while going up the entrance ramp and boom the truck feels like its coming apart. Slow down to 60 and all gone and get back up to 80 no problem. Does this sound like the same thing. I heard there was TSB on the steering stabilizer is this true.

    Chances are it's related to the trac bar system. If you have BFG tires that could be the cause as well.
