THE STEERTEK HAS A UNIQUE AXLE. THE KINGPIN IS CRYOGENICALLY INSTALLED IN THE AXLE.
THE KINGPIN IS A NON-REPLACEABLE COMPONENT OF THE AXLE ASSEMBLY. DO NOT TRY TO
REMOVE THE KINGPIN. DOING SO WILL DAMAGE THE AXLE AND MAY CAUSE LOSS OF VEHICLE
CONTROL, PERSONAL INJURY OR PROPERTY DAMAGE. IF THE KINGPIN SHOWS SIGNS OF
MOVEMENT, CONTACT HENDRICKSON PRODUCT ENGINEERING - TECH SERVICES.
1. Prepare and polish the kingpin by removing all grease and excess debris using a fine grit
(220 grit or higher) emery cloth and parts solvent, see Figures 9-50 through 9-53.

kingpin has less than 1.802" diameter, replacement of the axle is necessary, see
Figures 9-54 through 9-57.
