On a resent tour in my 15 roadster the play in the steering was about 4 inches which makes it hard work
Do i need a new gear case and gears as the rest of the steering gear looks ok
I have had the car for over 50 years
as suggested a front end checkout is in order. king pins, tie rod ends, pitman arm, wheel bearings, ect. That's the "easy" stuff. then move on to the steering wheel gears & case.
