Mike,
First off, welcome to the forum!
This issue sounds a lot like what happens to Jeep Wranglers and what they call the Death Wobble where the front end shakes violently after hitting a hard bump or pot hole. For the Jeep (which has a solid front axle assembly) the track-bar is usually the culprit though any loose connections in the front end can contribute.
Normally I would recommend replacing most of the components you already have so, no need to go there except to say that I hope you went with urethane bushings as they allow less movement.
That said, the death wobble is a result of loose front end components or components disconnected (as in the case of the Jeeps where we disconnect the front links that tie the sway bar to the frame to allow more wheel travel). Next up was the addition of the steering stabilizer which almost always does the trick even though you can feel the truck want to shake.
I would still take a few minutes with the truck up on a lift or jack stands and look for any play in any of the front end components to include the rack and pinion, sway bars and connecting rods/links. Again, if you went with rubber versus urethane bushings you can still change those out and that will help.
