shimmy between 45 & 50, fixed deth wobble

[chevyguygoneford]

shortly after buying my 2005 f350 6.0 4X4 super duty,among engine trouble i started having severe deth wobble when i would hit a bump, the first time it did it, it put me in the ditch with my wife, kids and a horse trailer hauling two draft horses. bad day but but everyone and all equpment was fine. anyways to help out a bit i replaced the two almost bald front baja atz tires and got nothing then i replaced the stearing stableizer and completly fixed the problem so im going to put a dual stabelizer on it this winter i belive that is going to be the proper fix. my new issue is the truck shimmys back and forth between 45 & 50 only dead on the money mostly under braking. i know 100 percent sure it is not the brakes all new everything and was fine after replaced. i am going to replace all 4 shocks with rough country nitro 9000's and then be on the hunt for a bad bushing somewere. also truck in no start condition the plugs going to the (ficm) were broke and came unpluged from last owner's handy work so i ziptied around the ficm and plugs replaced turbo and batterys and ran like new. hope that helps someone and imput appriciated.

I'd add more castor, check the track bar bushings and Tq. Get Bilsteins..will be happyer IMO. If I can help..pricing etc please PM.
