THE SPRING CENTER BOLT IS NOT THE PROPER SIZE OR LENGTH. AS A RESULT, LOCATION AND ALIGNMENT OF THE SPRING TO THE FRONT AXLE MAY NOT BE CORRECT. IF THE FRONT SPRING CLIPS LOOSEN, THE INADEQUATE CENTER BOLT MAY RESULT IN SPRING TO AXLE MISALIGNMENT, SHIFTING OF THE AXLE, AND LOSS OF STEERING CONTROL.
THE DEFECT WILL BE CORRECTED BY THE ADDITION OF A SPACER BETWEEN THE SPRING AND THE CENTER BOLT HEAD TO INCREASE THE EFFECTIVE HEAD LENGTH. A LONGER CENTER BOLT WILL ALSO BE INSTALLED FOR POSITIVE RETENTION.
