front end wobble

Can anyone help... 95 f-350 p.s. deisel front end wobbles bad if hit a bump in road. replaced tie rods ball joints . everything tight can not figure out..

I'm not a total gear head- but if you have a solid I-beam front end it very well could be a king pin. I know this problem well, a couple E350's and a Old P500 chassis StepVan.

Gets kind of hairy steering after the bumps!

As I recall most 350 and larger trucks use a steering dampner between the drag link and the axle. If it is weak, this sould happen.
