Hi Steve,
Is the gear box and steering assembly out of the Willys?� Are you trying to remove the long inner shaft from the gear box, and tube?� If so, you will need to remove the sector shaft first.
Remove the pitman arm.� Remove the gear box cover.� Pull the sector shaft out.� Loosen the tube clamp and remove the three bolts from the top of the gear box.� You can now pull the shaft.
Note:� There are ball bearings and races in there.� 11 bearings on top and 11 on the bottom of that worm gear portion of that shaft.
Are you rebuilding the steering?
