1967 gtx steering issues

[Brian B body]

Hey guys I am having trouble with my 67 gtx steering I had a front end alignment done but when I am going down the road with the wheel straight every now and then the car pulls suddenly to the left without the steering wheel moving and I have to correct it the shop told me all my bushings and stuff were good could this be a steering gearbox issue

many help is appreciate thank you

I doubt it is a gear box issue. Power or manual steering. Are you hitting a bump when this happens? Do you have a copy of what the car was set at when aligned?

Yes let see the alignment specs.

Tires grabbing grooves in the road
bad idler arm
Toe out
bias ply tires
What size tires front & rear
Has the suspension height been altered from stock?Is the back end jacked up
Is the car lowered?

there are so many questions.
