jerky steering

ok guys i need some help with this one. Its weird so Im gonna explain it the best I can. Best example I have is when exiting and off ramp on interstate the steering seems to catch and then let loose and then catch again. does it going straight too. its a 93 coupe. belt is good, rag joint seems to be good, tensioner is good, IDK whats going on? help

Is the steering shaft rubbing the headers?

Sounds to me like you have either a handful of bushings going out OR tie rod ends.

could possibly be just a simple rack and pinion going south... sounds like the rail gear is and just wore out.... im not ruling out a possibility of a bad steerying shaft either... if it was a bad a tie rod or rods, you have more obvious looseness 100% of the time, if not set the front end on the ground... you also could have excessive caster issue as well. do you have camber/caster plates?
