Buildanother and Lefty are right:

- You will get all kinds of diagnosis' and some of them might even get the problem to go away....for awhile. You have Death Wobble (or DW for short) it isn't limited to 3rd gens as lots of 2nd gen trucks do it as well as Fords and Jeeps. Things like lift kits, large load range D tires, front end leveling kits, worn steering stabilizers, track bars and other front end components can set it off, BUT the underlying cause is the design of the suspension itself coupled with improper caster settings. You'll get many people telling you that shocks or tires or trackbars "cured" the problem for them, but I would contend that they've put the problem in "remission" and the underlying condition will manifest itself again once there is some more play in the system. All you do by changing shocks (for example) is close the "path of least resistance".

My advice: replace any or all worn components and have a competant alignment shop dial in the appropriate positive caster: NOT "within tolerances" according to DC, the proper amount (sorry don't remember the exact figure).
