Suspension systems, wheel spindle assemblies, and methods of retrofitting wheel spindles

1. A method of mounting to an A-arm suspension system a wheel spindle configured for use with a multi-link suspension system, comprising:

removing at least one suspension link mount on the wheel spindle;

mounting a ball joint bracket to the wheel spindle, the ball joint bracket being configured to mount to the A-arm suspension system, said removing and said mounting steps producing a modified wheel spindle; and

mounting the modified wheel spindle to the A-arm suspension system.

2. The method of claim 1 , wherein removing the at least one suspension link mount on the wheel spindle comprises removing first and second lower bushing mounts on the wheel spindle.

3. The method of claim 2 , wherein said removing comprises removing the first and second lower bushing mounts by machining.

4. The method of claim 1 , wherein said mounting the ball joint bracket to the wheel spindle comprises mounting the ball joint bracket to hub assembly mounting holes provided on the wheel spindle.

5. The method of claim 1 , further comprising relocating a toe link mount on the wheel spindle, said removing, said mounting, and said relocating steps producing the modified wheel spindle.

6. The method of claim 5 , wherein said relocating comprises relocating the toe link mount to a position where the relocated toe link mount is substantially aligned with a centerline of a ball joint axis that is defined when the modified wheel spindle is mounted to the A-arm suspension system.

7. The method of claim 6 , wherein said relocating comprises:

removing a toe link mounting stud from the wheel spindle; and

drilling a relocated hole in the wheel spindle, the relocated hole being substantially aligned with the centerline of the ball joint axis.

8. The method of claim 7 , further comprising installing the mounting stud in the relocated hole.

9. The method of claim 7 , further comprising machining a new toe link bearing surface on the wheel spindle adjacent the relocated hole.

10. The method of claim 7 , further comprising mounting a toe link to the relocated hole.

11. The method of claim 6 , wherein the relocated toe link mount defines a mounting axis that is substantially parallel to an axis of rotation of at least one A-arm of the A-arm suspension system.

12. The method of claim 1 , wherein said mounting the modified wheel spindle to the A-arm suspension system comprises:

mounting the modified wheel spindle to an upper ball joint provided on an upper control arm of the A-arm suspension system; and

mounting said ball joint bracket to a lower ball joint provided on a lower A-arm of the A-arm suspension system.
