I have a F250 power stroke 2 wheel drive and having or had a problem with the front end shaking when driving. Ive looked into a few things but really with out spending and tearing out every little thing, I have really no clue where too start. I did put a new steering shaft in it.

 

welcome to diesel bombers have you had it aligned in a while what kinda shape is your front tires in jack up the front end and do the shake test look and feel for anything loose

 

I had a 2000 F250 2wd company truck that had serious chopping action in the front end when hitting expansion joints or potholes. It wouldn't stop until you slowed wayed down. The dealer ended up replacing all the C-bushings, track bar, and I can't remember what before they got it to stop. Basically replaced the whole front end.

 

I have a 96 f-250 4x4 7.3 had same problem after much work and some $ I installed a $62.00 steering stabilizer problem solved.
