A king pin cap tool kit comprises a pair of cap removal tools for removing MACK(R) truck king pin caps of different diameters and a pair of thread chasers for repairing internal threads in steering knuckle housing bores of corresponding diameters. Each cap removal tool comprises a cylindrical body having a cruciform protrusion extending from one end face and a polygon-shaped recess through the opposite end face to adapt the cap removal tool for driving connection to a conventional pneumatic impact gun. The cruciform protrusion is uniform in its height and includes a pair of intersecting legs that extend fully across the end face in diametrical fashion. A cap removal tool having three intersecting legs is also disclosed. Each thread chaser comprises a cylindrical body having opposite end faces, a threaded peripheral surface, and polygon-shaped axial through hole for receiving a breaker bar or ratchet with extension. At least one groove, and preferably a plurality of grooves, are provided in the threaded peripheral surface from one end face to the other for channeling material removed by the thread chaser. The thread chaser has a leading thread near each end face to make it reversible in mounting on the breaker bar or ratchet.
