Hey everyone. So I've got about 1800 miles on the chevelle since its been on the road. The one issue I have is that driving on the california highways the car is hunting pretty bad when it finds the grooves in the concrete. I understand that the tires come into play with this, but I'm wondering if I can change anything else to help with the problem. The car has a full airride suspension, Strongarms up front, and BMR adjustables in the rear. I also installed Howe Low friction ball-joints, AGR variable ratio box with stock steering linkages. When I had the alignment done I asked them to add in some caster and a little toe in but I don't have anyspecs as to how much they added. Sometimes its down right scary, driving in LA traffic at 75mph and the car finds a groove it likes. What can I do to help this? Do new corvettes have this problem, I know they run wide staggered tires. Also will lowering the pressure in the steering box help. It seems that when the car is off, the steering box has a little play in it( Like you move the wheel and it doesn't moves the tires).
As always, any help is appreciated.

of your ball joints, tie rods, etc are new. First thing I would do is have the alignment checked again after you call ART and get the alignment specs they reccommend for their system. Also have a 4 wheel done to make sure the rear is square in the car and with your front wheels.
What you describe is a bad bump steer problem, worn parts or bad alignment. I am assuming it is the alignment.
In my younger days, I rebuilt the front end of my 72 C10. I put the drag link on backwards (it fits both ways) It stumped me and the alignment guy for a week until I figured it out. It would behave just like you stated in your above post.
