I've got a question here.  I have a 2004 Dodge Ram 2500.  I put a level kit on (2inch) and 315 70r 17 tires on.  I had the alignment done and put a steering stabilizer on hoping it would help but didn't.  The problem is when I go down the freeway 60 to 70mph,  I hit a bump just right and the truck starts to shake violently till I slow down to 25mph.  Has anyone heard anything similar to this.  I checked all the suspension components and the truck only has 26000 miles on it.  Any info would be great.

Classic "death wobble", many things can cause it, has to be something in your steering/ front end.  

Did it do it before you put the leveling kit on it? If not maybe something is misaligned or something with the leveling kit.  

It started after I put the leveling kit in.  I have someone else looking at it. Maybe they can find something I didn't.  Thanks for the input.

Have the alignment shop re-check the caster angle. Even a change of  1 deg caster can cause a "death wobble" at certain speeds.  

I had the  death wobble  on my tow truck once it was cause of loose front end parts  a little slop can make for a BIG wobble  so please  recheck  your  instalation  and steering  components bet you may find a  sloppy pitman arm  i did
