Ok on my '66. I still think a new steering box will fix it. I've adjusted it and it still has a pretty good amount of play. If you shake and fiddle w/ my suspension its all solid tight and new. Going down the road it tracks a little off. Sometimes if I go over a hill at a higher speed when I drop off and the load moves off the car as its pushed over the hill sometimes it will cause the wheels to jerk and when the load comes back to the front suspension the car wants to jerk to the side bad sometimes. It does it sometimes on potholes and things but especially coming out from under load on a hill. Going straight and downhill it does alright buuuut. Any ideas here? Think getting it aligned again could cure that? Maybe they just didn't do a good job the last time and it's got the wheels tryin to go different ways? It's got new shocks, control arms, pitman/idler arm, bushings, etc. Tight as can be but my steering scares me sometimes....its just sloppy and jerky.
