The hydroformed steering knuckle assembly also includes at least one component secured to the hydroformed main body. The hydroformed main body is a hydroformed monolithic structure being integral, unitary, and one-piece.

Claims (15)

1. An assembly adapted for use with a vehicle having at least one pivotal wheel and remainder non-pivotable vehicle structure, said assembly comprising:

a steering knuckle including a hydroformed main body pivotally connectable to the structure, and interconnecting the structure and wheel, and at least one component secured to said hydroformed main body,

wherein said body is a hydroformed monolithic structure being integral, unitary, and one-piece, and defines a hollow interior.

2. The assembly as set forth in claim 1 wherein said at least one component comprises at least one of a steering arm attachment, strut fastener attachment, caliper anchor plate attachment, bearing attachment, steering arm ball joint attachment, and lower control arm ball joint attachment.

3. The assembly as set forth in claim 1 wherein said hydroformed main body has at least one aperture extending therethrough to receive said at least one component.

4. The assembly as set forth in claim 1 wherein said hydroformed main body has a closed perimeter with a hollow interior.

5. The assembly as set forth in claim 1 wherein said hydroformed main body comprises a base wall, an annular side wall extending outwardly from said base wall, and a bracket wall extending longitudinally from said base wall.

6. The assembly as set forth in claim 5 including at least one weld to secure said at least one component to said hydroformed main body.

7. The assembly as set forth in claim 6 wherein said at least one weld joins said at least one component to a surface of said base wall of said hydroformed main body.

8. The assembly as set forth in claim 1 wherein said hydroformed main body is made of a metal material.

9. The assembly as set forth in claim 1 wherein said at least one component is made of a metal material.

10. An assembly adapted for use with a vehicle having at least one pivot wheel and remainder non-pivotable vehicle structure, said assembly comprising:

a steering knuckle including a hydroformed main body pivotally connectable to the remainder vehicle structure, interconnecting the remainder and wheel, and including a base wall, an annular side wall extending outwardly from said base wall, and a bracket wall extending longitudinally from said base wall to form a closed perimeter having a hollow interior; and

at least one component secured to said base wall of said hydroformed main body,

wherein said hydroformed main body is a hydroformed monolithic structure being integral, unitary, and one-piece.
