True that: "Death wobble from coil sprung front suspension"
My van is fitted with a 2007 F350/F250 coil Dana 60 front axle/suspension. After spending $3000 with the 4x4 converter to cure my DW. I finally researched it myself and cured it with dual opposing gas pressurized shocks as a steering stabilizer. The solid axle/ coil front suspension is prone to DW. Not all of them have it. But when you have one that DW's you know it. I read somewhere that the 7.3L sold more units that the Duramax and Cummins combined. So, there will likely be a supporting aftermarket for some years to come.
