A king pin is mounted in a hollow axle. An insert is force fit into each end of the hollow axle. The insert includes an aperture that aligns with an aperture in a wall of the hollow axle to provide a mount structure for the king pin. This mount structure thus provides a solid and reliable mount in a very simplified manner. The hollow axle and insert are also provided with draw key holes such that bolts may lock the king pin within the insert and the hollow axle.

What is claimed is: 1. A steer axle comprising: an axle body having a pair of spaced ends, said axle body being generally hollow at each of said pair of spaced ends; an insert inserted into at least one of said pair of spaced ends such that said insert is non-rotatable relative to said at least one of said pair of spaced ends; an aperture formed within at least one wall of said at least one of said pair of spaced ends, and through at least a portion of said insert; at least one draw key hole formed through said axle body and said insert; and a king pin mounted within said aperture. 2. The steer axle as set forth in claim 1, wherein said aperture is formed through both of a top and bottom wall of said axle body, and entirely through said insert. 3. The steer axle as set forth in claim 1, wherein said at least one draw key hole intersects said aperture within said insert, and including a lock member inserted through said at least one draw key hole to lock said king pin within said aperture. 4. The steer axle as set forth in claim 3, wherein said at least one draw key hole comprises a pair of draw key holes each including one lock member. 5. The steer axle as set forth in claim 1, wherein each end of said pair of spaced ends includes said insert and king pin. 6. The steer axle as set forth in claim 1, wherein each spaced end includes a hollow section bounded by said at least one wall, and including a force fit interface between said insert and said at least one wall of said spaced end to attach said insert to said axle body such that said insert substantially fills said hollow section. 7. A method of forming a steer axle including the steps of: (1) providing a hollow axle body having a pair of spaced ends, said hollow axle body being generally hollow at each of said pair of spaced ends; (2) inserting an insert into each end of said pair of spaced ends such that said inserts are non-rotatable relative to said pair of spaced ends; (3) providing an aperture within at least one wall at each end of said pair of spaced ends, and through at least a portion of each of said inserts; and (4) forming at least one draw key hole through said hollow axle body and said insert at each end of said pair of spaced ends. 8. The method as set forth in claim 7, including forming said apertures through both of a top and bottom wall of the hollow axle body, and entirely through each of said inserts. 9. The method as set forth in claim 7, including inserting a king pin into each of said apertures. 10. The method as set forth in claim 9, wherein each draw key hole intersects said aperture within said insert, and including inserting a lock member through each of said draw key holes to lock said king pins within said apertures. 11. The method as set forth in claim 10, wherein said at least one draw key hole comprises a pair of draw key holes at each end, and including inserting a lock member through each draw key hole. 12. The method as set forth in claim 7, including force fitting said inserts into said pair of spaced ends such that each insert is fixed to said hollow axle body. 13. The method as set forth in claim 7, including substantially filling said hollow axle body at each of said pair of spaced ends with said inserts. 14. A steer axle comprising: an axle body having a pair of spaced ends, said axle body being generally hollow at each of said pair of spaced ends; an insert inserted into at least one of said pair of spaced ends such that said insert is non-rotatable relative to said at least one of said pair of spaced ends; at least one draw key hole formed through said axle body and said insert; and a king pin aperture formed within at least one wall of said at least one of said pair of spaced ends, and through at least a portion of said insert, said aperture to receive a king pin therein. 15. The steer axle as set forth in claim 14, wherein a king pin is mounted within said king pin aperture. 16. The steer axle as set forth in claim 15, wherein said king pin aperture is formed through both of a top and bottom wall of said axle body, and entirely through said insert. 17. The steer axle as set forth in claim 15, wherein said at least one draw key hole intersects said king pin aperture within said insert, and including a lock member inserted through said at least one draw key hole to lock said king pin within said king pin aperture. 18. The steer axle as set forth in claim 17, wherein said at least one draw key hole comprises a pair of draw key holes each including one lock member. 19. The steer axle as set forth in claim 14, wherein each end of said pair of spaced ends includes said insert and king pin. 20. The steer axle as set forth in claim 14, wherein each spaced end includes a hollow section bounded by said at least one wall and wherein said insert substantially fills said hollow section. 21. The steer axle as set forth in claim 14, including a force fit interface between said insert and said at least one wall of said spaced end such that said insert is attached to said axle body. 22. The steer axle as set forth in claim 14, wherein said axle body includes a large dimension section that transitions into a pair of spaced angled sections which then transition into said pair of spaced ends, and wherein said insert comprises a polygonal block that extends to an inner extent adjacent a transition between one spaced end and an associated angled section.
