Ok , just to be different , here's a different approach . First , center the steering box by turning the wheel from lock to lock while counting turns , then set the wheel to the center point . So, if it turns 4 times , set it at 2 turns . Next , get under the front end and look at the pitman arm . If all is aligned in the World , that arm should be parallel with the frame . If it is not , fix it now by removing the nut and using a pitman arm puller . Do not ever hammer on a pitman shaft in a steering box , you will destroy it . Once the arm is parallel with the frame , make sure at that point the wheels are straight ahead as they should be . You can use a long straight peice of steel and hold it against both front and rear tires on either side to tell whether or not the front wheels are straight . If they are not , adjust the end of the drag link to center the wheels to the steering box . Once that is done , look at the steering wheel . If it is not aligned at center , remove the horn button cover and remove the wheel with a 2 bolt puller . Do not smack the end of the shaft with any object as you will destroy the steering column and it's collapsible bushings . For those who have smacked theirs , there is a section in the fsm that details how to tell if the wheel has been hit in an accident by checking the distance on the column shear points . I have seen two Zuks so far that have developed loose wheel problems due to this , so it's worth a look . Now that everything is properly aligned , make sure to road test and check all fasteners to make sure they are tight and the vehicle drives straight . You may find that with the wheels set straight against the rear tires , it may not steer properly or straight . If that is the case , set the wheels straight ahead again and take wheelbase measurements to see if the frame or spring perches are off causing it to "dog track" . Correct as needed
. Now, the reason for doing all of this . If the steering box is not centered first , it will never work correctly since the box has a "center point" in how they work . There are some excellent writeups on the net about this and how to properly adjust the box itself , worth a read sometime . Now , get to work and have fun.....
