the first stabilizer bolt is supported by the first stabilizer plate such that axial rotation of the first stabilizer bolt displaces the first stabilizer head relative to the first stabilizer plate; and

the second stabilizer bolt is supported by the second stabilizer plate such that axial rotation of the second stabilizer bolt displaces the second stabilizer head relative to the second stabilizer plate.

12. A king pin removal tool as recited in claim 1 , in which the first and second stabilizing bolts engage opposing sides of the axle member to prevent rotation of the drive plate relative to the axle member when the first drive member is rotated relative to the drive plate.

13. A king pin removal tool as recited in claim 1 , further comprising:

a second drive member; and

an adapter plate; whereby

the drive plate is adapted to support the adapter plate and the second drive member engages the adapter plate such that rotation of the second drive member relative to the drive plate displaces the second drive member through the drive opening and along the king pin axis.

14. A king pin removal tool as recited in claim 1 , in which the anchor plate defines an exit opening, where the first drive member displaces the king pin member through the exit opening.

15. A king pin removal tool for displacing a king pin along a king pin axis relative to an axle member and a knuckle assembly, the king pin removal tool comprising:

a drive plate defining a drive opening;

an anchor plate defining an exit opening;

a first drive member;

first, second, third, and fourth spacing rods extending between the drive plate and the anchor plate;

first and second stabilizer plates; and

first and second stabilizer bolts; whereby

the first, second, third, and fourth spacing rods support the drive plate and the anchor plate relative to the king pin such that the first drive member is aligned with the king pin axis;

the first drive member engages the drive plate such that rotation of the first drive member relative to the drive plate displaces the first drive member through the drive opening and along the king pin axis to displace the king pin along the king pin axis relative to the axle member and the knuckle assembly and through the exit opening;

the first spacing rod extends through the first stabilizer plate such that the first stabilizer plate rotates relative to the first spacing rod;
